Abstract:
In Inverse Synthetic Aperture Radar (ISAR) systems the motion of the target can be classified in two main categories: Translational Motion and Rotational Motion. A small degree of rotational motion is required in order to generate the synthetic aperture of the ISAR systems. On the other hand, the remaining part of the target&rsquo
s motion, that is any degree of translational motion and the large degree of rotational motion, degrades ISAR image quality. Motion compensation techniques focus on eliminating the effect of the targets&rsquo
motion on the ISAR images. In this thesis, ISAR image generation is discussed using both Conventional Fourier Based and Time-Frequency Based techniques. Standard translational motion compensation steps, Range and Doppler Tracking, are examined. Cross-correlation method and Dominant Scatterer Algorithm are employed for Range and Doppler tracking purposes, respectively. Finally, Time-Frequency based motion compensation is studied and compared with the conventional techniques. All of the motion compensation steps are examined using the simulated data. Stepped frequency waveforms are used in order to generate the required data of the simulations. Not only successful results, but also worst case examinations and lack of algorithms are also discussed with the examples.

Abstract:
A proper time-frequency transform technique suppresses the blurring and smearing effect of the time-varying Doppler shift on the target image. The conventional target imaging method uses the Fourier transform for extracting the Doppler shift from the received radar pulse. Since the Doppler shift is timevarying for rotating targets, the constructed images will be degraded. In this thesis, the Doppler shift information required for the Range-Doppler image of the target is extracted by using high resolution time-frequency transform techniques. The Wigner-Ville Distribution and the Adaptive Gabor Representation with the Coarse-to-Fine and the Matching Pursuit Search Algorithms are examined techniques for the target imaging system. The modified Matching Pursuit Algorithm, the Matching Pursuit with Reduced Dictionary is proposed which decreases the signal processing time required by the Adaptive Gabor Representation. The Hybrid Matching Pursuit Search Algorithm is also introduced in this thesis work and the Coarse-to-Fine Algorithm and the Matching Pursuit Algorithm are combined for obtaining better representation quality of a signal in the time-frequency domain. The stated techniques are applied on to the sample signals and compared with each other. The application of these techniques in the target imaging system is also performed for the simulated aircrafts.

Abstract:
In this thesis, Inverse Synthtetic Aperture Radar image reconstruction techniques, named as Range Doppler, Back Projection, Polar Formatting, Multiple Signal Classification (MUSIC) and Time Frequency techniques are analysed and compared using simulations. Time Frequency techniques investigated in this thesis are Short Time Fourier Transform, Wigner-Ville Distribution, Smoothed Wigner-Ville Distribution and Choi-Williams Distribution. First, some fundamental concepts of ISAR, such as resolution, range profile, time dependent Doppler frequency are given. A data simulator is designed and implemented for the purpose of providing configurable input to ISAR signal processing algorithms for a given ISAR target geometry. Estimation of target rotational velocity is explained with the help of three methods, namely Grid Search, WVD Slope and Radon Wigner-Hough Transform. Then, theoretical background of image formation algorithms is discussed. MATLAB simulations for each algorithm are implemented with several configurations in order to visualize and analyse the results. Finally, processing algorithms are compared to discuss the advantages and disadvantages.

A frequently useful technique in the interpretation of Inverse Synthetic Aperture Radar (ISAR) images is to construct a three dimensional (3D) model of the object being imaged. Generally, such models are constructed manually by an analyst based on a series of radar images and whatever other information is available. However, using multistatic radar, it is possible to generate 3D Interferometric ISAR (IFSAR) point cloud images. In this thesis, two original techniques for automatically generating models of rigid bodies from IFSAR point clouds are explored. One technique extends the concept of the visual hull to a composite point cloud. The other uses a noise resistant estimator to determine the shape of the side of the object presented to the radar. Noise and radar artifacts show up strongly in the data, and both techniques must reject them to achieve good performance. Additionally, an optimization-based algorithm was devised to determine the angular velocity of a target using only one interferometric baseline. Knowing the angular velocity of the target is necessary to correctly scale the axes of ISAR images and IFSAR point clouds. Though techniques exist for angular velocity determination using multiple baselines, receiving antennas are expensive and are not always available. The techniques presented in this thesis were tested against simulated data and data collected in a compact range. The angular velocity determination technique was successfully demonstrated on simulated IFSAR data, using a particular heuristic enforcing the consistency of rotational motion. Investigation into a more robust heuristic is necessary to make the approach broadly effective. The surface reconstruction algorithm based on the noise resistant estimator performs very well, doing much better than a traditional algorithm selected for comparison (3D a-shapes) in high noise situations. The technique based on the visual hull, while producing faithful reconstructions in some cases, generally offers performance inferior to the noise resistant estimator. Quantitative measurements were used to evaluate the fidelity of the models generated by the various techniques.

Abstract:
In this thesis a stepped-frequency Inverse Synthetic Aperture Radar (ISAR) is employed to develop two-dimensional range-Doppler images of a small ghter aircraft which exhibits three dimensional rotational rotation. The simulation is designed such that the target can exhibit yaw, pitch and roll motions at the same time. First, radar returns from prominent scatterers of various parts of the target are processed and displayed using conventional Fourier transform. The eects of dierent complex motion types and scenarios are observed and discussed. Then, several linear and bi-linear time-frequency distributions including shorttime Fourier transform, Wigner-Ville, pseudo Wigner-Ville, smoothed pseudo Wigner-Ville, Choi-Williams, Born-Jordan and Zhao-Atlas-Marks distributions are applied to the same target and scenarios. The performance of the transforms is compared for each scenario. The reasons for success of the distributions are discussed thoroughly.

Abstract:
Approved for public release; distribution in unlimited.
An imaging radar, like ISAR, offers a combatant the capability to perform long range surveillance with high quality imagery for positive target identification. Extending this attractive feature to the battle damage assessment problem (BDA) gives the operator instant viewing of the target's behavior when it is hit. As a consequence, immediate and decisive action can be quickly taken (if required). However, the conventional Fourier processing adopted by most ISAR systems does not provide adequate time resolution to capture the target's dynamic responses during the hit. As a result, the radar image becomes distorted. To improve the time resolution, time-frequency transform (TFT) methods of ISAR imaging have been proposed. Unlike traditional Fourier-based processing, TFT's allows variable time resolution of the entire event that falls within the ISAR coherent integration period to be extracted as part of the imaging process. We have shown in this thesis that the use of linear Short Time-Frequency Transforms allows the translational response of the aircraft caused by a blast force to be clearly extracted. The TFT extracted images not only tell us how the aircraft responds to a blast effect but also provides additional information about the cause of image distortion in the traditional ISAR display.

Abstract:

By analyzing ISAR images, the characteristics of military platforms with respect to radar visibility can be evaluated. The method, which is based on the Discrete-Time Fourier Transform (DTFT), that is currently used to calculate the ISAR images requires large computations efforts. This thesis investigates the possibility to replace the DTFT with the Fast Fourier Transform (FFT). Such a replacement is not trivial since the DTFT is able to compute a contribution anywhere along the spatial axis while the FFT delivers output data at fixed sampling, which requires subsequent interpolation. The interpolation leads to a difference in the ISAR image compared to the ISAR image obtained by DTFT. On the other hand, the FFT is much faster. In this quality-and-time trade-off, the objective is to minimize the error while keeping high computational efficiency.

The FFT-approach is evaluated by studying execution time and image error when generating ISAR images for an aircraft model in a controlled environment. The FFT method shows good results. The execution speed is increased significantly without any visible differences in the ISAR images. The speed-up- factor depends on different parameters: image size, degree of zero-padding when calculating the FFT and the number of frequencies in the input data.

Abstract:
750 bis 1.000 türkische Sepharden lebten in den 1920er und 1930er Jahren in Deutschland und bildeten damals die Mehrheit der ersten Migrantengeneration aus der Türkei. In Berlin gründeten sie eine eigene Gemeinde, die bis zur Auslöschung durch die Shoah die größte sephardische Gemeinde in Deutschland war. Trotz ihrer überschaubaren Zahl bildeten diese türkischen Sepharden keineswegs eine homogene Gruppe. Sie unterschieden sich nach Migrationszeitpunkt, sozialem Status sowie nicht zuletzt im Verhältnis zu ihrem Herkunftsland. Der Artikel untersucht die Geschichte dieser Community vor allem als Migrationsgeschichte.
Between 750 and 1,000 Turkish Sephardim were living in Germany during the 1920s and 1930s; they thus constituted the majority of the first generation of Turkish migrants in Germany. In Berlin they built their own congregation, which became the biggest Sephardic community in Germany until its annihilation during the Shoah. Despite their limited numbers, these Turkish Sephardim did not constitute a homogeneous group. They differed with respect to their year of immigration, their social situation and their relation to their country of origin. The article narrates the history of the Sephardim in Germany as a history of migration.

Abstract:
Dans le cadre de la surveillance maritime, les opérationnels ont de plus en plus recours à l'imagerie radar pour classifier à grande distance un objet marin. Le traitement ISAR (Inverse Synthetic Aperture Radar) répond à ce besoin. Il repose en particulier sur l'analyse des mouvements propres de l'objet marin. Une fois l'objet détecté, il s'agit d'afficher sur la console tactique la représentation de la fréquence Doppler en fonction de la distance, aussi appelée image range-Doppler. Le travail présenté dans ce mémoire s'inscrit dans une perspective d'évolution opérationnelle de la chaîne de traitement existante. Il vise à produire de manière automatique la « meilleure » image range-Doppler. Dans cette thèse, nos contributions s'appuient sur l'idée de reconsidérer la chaîne de traitement en tenant compte de l'a priori que l'objet marin est un objet rigide dont la géométrie structure l'évolution du signal radar. Ainsi, dans une première contribution, nous proposons une nouvelle méthode d'analyse temps-fréquence du signal radar afin d'obtenir une image instantanée où l'opérationnel peut distinguer « au mieux » les superstructures de l'objet marin. Cette dernière est fondée sur la fusion de plusieurs représentations temps-fréquence issues de la classe de Cohen en faisant l'hypothèse que les composantes temps-fréquence sont des trajectoires structurées 2D dans le plan temps-fréquence, contrairement aux termes d'interférences induits par la propriété de bilinéarité des membres de cette classe. Une étude comparative sur données synthétiques et ISAR est menée pour confirmer la pertinence de notre approche, notamment du point de vue de la résolution temps-fréquence et de la suppression des termes d'interférences.Dans une seconde contribution, nous établissons une nouvelle procédure pour qualifier chaque image range-Doppler, obtenue à l'issue de l'analyse temps-fréquence, avec des mesures d'irrégularité de formes que nous fusionnons à l'aide d'un opérateur d'agrégation. Des simulations sur données réelles sont réalisées. Les résultats concordent avec une analyse subjective menée par des opérationnels, ce qui confirme l'efficacité de notre méthode
In maritime surveillance, radar imaging plays a key role to classify a maritime object. ISAR processing is one of the solutions, which takes advantage of the object rotational motion to provide a range-Doppler image.The work, presented in this report, is an evolution of the existing ISAR processing chain. Therefore, our contributions are based on the processing chain reconsideration by taking into account the fact that the maritime object is a rigid object, the geometry of which influences the radar signal evolution.In a first contribution, we propose a new time-frequency analysis method based on the aggregation of some time-frequency representations obtained with Cohen class members. It consists in differentiating the signal, assumed to be characterized by 2-D near-linear stable trajectories in the time-frequency plane, and the cross-terms, assumed to be geometrically unstructured. A comparative study is then carried out on ISAR synthetic data to confirm the efficiency of our approach.In a second contribution, we present a new procedure to characterize each range-Doppler image, obtained from a time-frequency analysis, by means of shape irregularity measures that are combined with a fuzzy logic operator. To validate our approach, simulations on real data are done. The results are compared to a subjective analysis carried out with practionners

Este projecto de investigação surgiu da consciencialização dos problemas ambientais que o mundo de hoje enfrenta. Perante este cenário, as empresas devem tomar decisões correctas quanto à relação existente entre meio ambiente e o meio empresarial. Elas necessitam de informações confiáveis e claras acerca das perdas que as suas actividades provocam no meio ambiente, identificando e descrevendo os custos e ganhos ambientais associados. Numa primeira instância, a presente investigação pretende verificar o nível de aplicação das directrizes recomendadas pelo Intergovernmental Working Group of Experts on International Standards of Accounting and Reporting (ISAR, 1998) e pelo Global Reporting Iniciative (GRI, 3° versão 2000-2007) através da evidenciação de informações sobre o meio ambiente nos relatórios anuais das dez maiores companhias brasileiras do sector de papel e celulose, no ano de 2009. O segundo objectivo é propor uma estrutura de evidenciação da informação ambiental, tendo como base as directrizes submencionadas. Tentando responder as exigências do mercado e das empresas. Conclui-se que o conjunto de directrizes com melhores práticas de divulgação de informação ambiental é o GRI, sendo que foi utilizado, parcialmente, por todas as empresas incluídas na amostra. Em concomitância, conclui-se que há um predomínio da divulgação de informações qualitativas.
This research project arose from the awareness of environmental problems the world faces today. Given this scenario, companies should make correct decisions regarding the relationship between environment and business environment. They need clear and reliable information about the losses that their actions cause to the environment, identifying and describing the costs and associated environmental gains. In the first instance, this research intends to investigate the level of implementation of the guidelines recommended by the Intergovernmental Working Group of Experts on International Standards of Accounting and Reporting (ISAR, 1998) and the Global Reporting Initiative (GRI, 3rd version from 2000 to 2007) by disclosure of information about the environment in the annual reports of the ten largest Brazilian companies in the pulp and paper sector in the year 2009. The second objective is to propose a framework of disclosure of environmental information, based on the undermentioned guidelines. Trying to meet market demands and business. It follows that the set of guidelines with best practices for dissemination of environmental information is the GRI, and it was used, in part, by all companies in the sample. Concurrently, we conclude that there is a predominance of the disclosure of qualitative information.

Inverse Synthetic Aperture Radar (ISAR) images of sea vessels are a rich source of information for radar cross section (RCS) measurement and ship classification. However, ISAR imaging of sea vessels is a challenging task because the 3-D rotational motion of such vessels often gives rise to blurring. Blurry ISAR images are not desirable because they lead to inaccurate parameter estimation, which reduces the probability of correct classification. The objective of this thesis is to explain how 3-D rotational motion causes blurring in ISAR imagery and to develop effective techniques for imaging cooperative and non-cooperative sea vessels for RCS measurement and ship-classification purposes respectively. Much research has been done to investigate the effect of 3-D rotational motion on an ISAR image under the assumption that an object's axis of rotation is constant over the coherent processing interval (CPI). In this thesis, a new quaternion-based system model is proposed to characterise the amount of blurring in an ISAR image when a sea vessel possesses 3-D rotational motion over a CPI. Simulations were done to characterise the migration of a scatterer through Doppler cells due to the time-varying nature of the Doppler generating axis of rotation. Simulation results with realistic 3-D rotational motion show substantial blurring in the cross-range dimension of the resulting ISAR image, and this blurring is attributed to the time-varying nature of the angle of the Doppler generating axis of rotation and the object's rotation rate over the CPI.

Le travail réalisé dans le cadre de cette thèse s'intègre dans le domaine de la télédétection de l'environnement maritime. Il porte, d'une part sur l'étude de l'interaction d'une onde électromagnétique avec une surface maritime en présence d'une cible complexe et observée en configuration bistatique. D'autre part, le travail est complété par l'étude et l'analyse de l'influence sur cette interaction des différents paramètres à la fois liés à la cible et à l'environnement. Dans ce contexte d'étude, le présent travail s'articule autour de deux volets importants. Le premier vise l'étude et la simulation de la Surface Equivalente Radar (SER) d'une cible complexe placée dans un environnement marin. Et un deuxième volet applicatif qui traite l'imagerie radar ISAR d'une cible complexe. Afin de traiter le premier point, le modèle électromagnétique retenu est basé sur une combinaison de méthodes asymptotiques (Optique Physique (OP), Optique Géométrique (OG), Méthode des courants équivalents (MCE)) intégrant les phénomènes d'ombrage et les multitrajets. Afin d'introduire l'influence de la surface de mer sur la réponse électromagnétique de la cible dans son environnement, nous avons opté pour une représentation de la scène (cible+surface de mer) par un ensemble de facettes triangulaires. Dans ce cadre, la cible discrétisée par un maillage triangulaire est générée à l'aide d'un outil de CAO (CATIA V5), quant à la surface de la mer, elle est générée en utilisant le spectre de mer d'Elfouhaily (et le modèle de Debye pour la prise en compte des paramètres diélectriques de l'eau de mer). Enfin, afin d'appliquer la méthode développée dans le cadre de l'imagerie radar ISAR, le calcul de la SER de la cible navale a été effectué en considérant une nouvelle représentation de la cible en parallélépipèdes. La méthodologie proposée a été évaluée via des simulations ainsi que des expérimentations (dans la chambre anéchoïque de l'ENSTA Bretagne) sur un modèle générique d'un navire.

Abstract:
Le travail réalisé dans le cadre de cette thèse s’intègre bien dans le domaine de la télédétection de l’environnement maritime. Il porte notamment, d’une part sur l’étude de l’interaction d’une onde électromagnétique avec une surface maritime en présence d’une cible complexe et observée en configuration bi-statique. D’autre part l’étude est complétée par l’étude et l’analyse de l’influence des différents paramètres à la fois liés à la cible et aussi à l’environnement. Dans ce contexte d’étude, le présent travail s’articule autour de deux volets importants. Le premier vise l’étude et la simulation de la Surface Equivalente Radar(SER) d’une cible complexe placée dans son environnement maritime. Et un deuxième volet applicatif traite l’imagerie radar ISAR d’une scène observée, avec prise en compte des cibles présentes sur la surface. Afin de traiter le premier point, le modèle électromagnétique retenu est basé sur une combinaison de méthodes asymptotiques (Optique Physique (OP), Optique Géométrique (OG), Méthode des courants équivalents (MCE)). Pour l’étude de l’influence de la surface de mer sur la réponse électromagnétique de la cible, nous avons opté pour une représentation de la scène (cible+surface de mer) par un ensemble de facettes triangulaires. Dans ce cadre, la cible discrétisée par un maillage triangulaire est générée à l’aide d’un outil de CAO (CATIA V5), quant à la surface de la mer, elle est générée en utilisant le spectre de mer d’Elfouhaily (et le modèle de Debye pour la prise en compte des paramètres diélectriques de l’eau de mer). Enfin, pour l’application de l’imagerie radar ISAR, le calcul de la SER de la cible navale a été effectué en considérant une nouvelle représentation de la cible en parallélépipèdes. La méthodologie proposée a été évalué via des simulations ainsi que des expérimentations sur un modèle générique d’un navire
The work presented here interset with remote sensing of the maritime environment.It espacially carried with the study of electromagnetic scattering by sea surface with the presence of the target. This study is done in bistatic configuration. So, it is completed by the analysis of the influence of various parameters related to the target and also to the environment. In this context, this work focuses on two important parts. The first is the study and simulation of Radar Cross Section (RCS) of a complex target placed in the maritime environment.And the second part deals with the application of ISAR radar imagery of an observed scene, with consideration of target on the sea surface. We have opted for a combination between Physical Optics (PO), Geometrical Optics (GO) and Equivalent Edge Currents (ECM) (POGO/ EMC) to estimate the RCS. In order to take into account the infuence of sea surface, we have genereted a 2D sea surface from the Elfouhaily spectrum. In order to integrate the target into the scenario (the target in its environment, radar imagery), we propose a parallelepiped representation of the naval taget and RCS calculation. The proposed methodology was evaluated through simulations and measurements on a generic model of a ship

Abstract:
This paper presents the structure and basic elements of the Autosar software architecture. In addition, the configuration code generation options are presented for both MC-ISAR drivers and AURIX TriCore TC277 hardware modules using EB tresos Studio. For the purpose of possible integration of the electric motor control algorithms, configurations of the GTM and VADC hardware modules have been created and described to enable the generation of PWM signals along with synchronously triggered parallel analogue-to-digital conversions. For this purpose, an application interface including the PWM driver was also developed and described.

Abstract:
In order to prepare for the next in situ missions to Mars (MSL-2011 and ExoMars-2018), the objective of mythesis is to create a collection of relevant analogue rocks and minerals for calibrating and testing future (and existing) space flight instruments, in accordance with the geology of Mars. They were characterized using standard laboratory instrumentation (optical microscopy, Raman, IR, XRD, SEM, electron microprobe and ICP-MS), as well as by flight instrumentation in development (Mössbauer MIMOSII, ExoMars Raman and IR (MicrOmega) spectrometers). All the samples are described in an online database in the following web site: www.isar.cnrs-orleans.fr. A part of this thesis is dedicated to the development of a cathodoluminescence (CL) instrument that could potentially be adapted for space flight. Study of alteration processes of basalts on Earth that show some similarities to surface and subsurface processes occurring on Mars may help understand and interpret martian features. Therefore, to complete the collection, samples of hydrothermal and acidic weathered basalts were collected from the Skouriotissa mine in Cyprus. The mineralogical evolution of the basalt through different alteration facies was studied. Because terrestrial basalts are poorer in Fe and Mg than martian basalts, I synthesized two artificial martian basalts. The two artificial basalts are different in terms of cooling rate (~110°C/h and drop-quenched, >1200°C/h). Interestingly, the more slowly-cooled sample exhibits a spinifex texture, similar to that of komatiites. If similar basalts occur on Mars, such rocks when altered by aqueous processes may have astrobiological implications.

Abstract:
Sammanfattning Syfte och frågeställningar Syftet med studien är att undersöka hur friluftsliv tolkas och bedrivs inom svenska skolor utomlands, detta med hänsyn till länders olika klimatförhållanden och avsaknad av svensk allemansrätt. Frågeställningar - Överensstämmer friluftslivsundervisningen som bedrivs i de utomlandssvenska skolorna med läroplanens riktlinjer kring friluftsliv och hur kan detta gestaltas? - Hur kan friluftslivsundervisningen skilja sig mellan skolor i Sverige och svenska skolor utomlands? Metod En kvantitativ metod användes för att besvara studiens syfte; en enkät med både fasta- och öppna frågor. Enkäten riktades till lärare i idrott och hälsa verksamma på svenska skolor utomlands. Totalt av 19 existerande svenska skolor utomlands, valde 15 av dessa skolor att delta i studien och därmed besvara enkäten, varav fem manliga lärare och 10 kvinnliga lärare. Resultat Resultatet visade på att undervisningen skiljer sig mellan svenska skolor utomlands och skolor i Sverige. Framförallt skiljer sig innehållet för lektionerna men även upplägget av friluftsundervisningen. Friluftslivsundervisningen i de svenska skolorna utomlands stämmer för det mesta överens med läroplanens riktlinjer. Var femte lärare (20%) angav att de bortsåg från moment ifrån kursplanen med argument för svårigheter i genomförandet p.g.a. materialbrist eller tillgång till ett visst klimat. Slutsats Lärare i idrott och hälsa, verksamma i svenska skolor utomlands tolkar läroplanen och tillhörande kursplan i idrott och hälsa (Lgr11) generellt på ett sådant sätt att det hade passat för undervisning i Sverige med tillgång till svenska skogar snö och isar. Samt tillgängligheten av skalenliga kartor för orientering och rättigheter för specifika aktiviteter i naturen i och med allemansrätten. Dock anpassas undervisningen i de svenska skolorna utomlands med alternativa lösningar, en stor del (80%) av lärarna menar att kursplanen i idrott och hälsa kan följas fullt ut medans resterande andel av lärarna angav att vissa undantag till kursplanen måste tas i beaktande.

Abstract:
This study is called When the ice of the Arctic melts is the world defrosting? and written by Rebecca Fröling. The purpose of the study is to investigate how the concept ‘security’ is used in the Swedish arctic strategy and why the concept is described in that way. The debate of the concept ‘security’ has been going on for years, but the debate is still present today. What we put in to the concept is operative for how we regard and discuss security and security politics. To analyze the strategy I used two theories, one with a traditional approach and one with a critical approach to security: Realism and Copenhagen School. The method that has been applied to the study is qualitative content analysis, to be able to analyze the text on the depth. To complement the analysis I interviewed three scientists in the field of security and Arctic politics. The analysis pointed out that the strategy still has a traditional point of view in the way of observing the object of security. But the traditional idea is starting to disintegrate and the critical perspective has been taking its place. The scientists have a more critical perspective, even thou it does not show in the strategy.
