Abstract:

This thesis describes research performed into the segmentation and classification of features on images of wound terrain generated from an airborne millimetre wave radar. The principles of operation of the radar are established and it is shown how an image is produced from this particular radar. The parameters such as wavelength, antenna size and pulse length are related to the images and a mathematical description of the radar data is given. The effectiveness of established image processing techniques is reviewed when applied to millimetre wave radar images and a statistical classification te

Abstract:

This thesis presents the development of various methods for measuring rainfall rates using horizontally-pointing millimetre-wave radars. This work builds from the combination of a T-matrix scattering model that allows the scattering from almost arbitrarily pro led rotationally symmetric particles to be calculated, and drop shape models that allow the effects of temperature and pressure on the shape to be taken into account. Many hours of rain data have been collected with 38 and 94 GHz FMCW radars, as well as with a disdrometer and weather station. These have been used to develop single- and d

Abstract:

The application of Quasi Optical techniques has been of great benefit to the field of instrumentation for frequencies between 750Hz and several hundred OHz. The application of Quasi Optical techniques to millimetre wave radar, described in this thesis, has produced an FMCW Doppler radar capable of operation at 940Hz and 1400Hz. Total polarization agility and a capability to operate over a very wide bandwidth is demonstrated. Quasi Optical circuits are proposed as solutions for many of the system requirements, and these are fully analyzed. Significant benefits of these techniques are demonstrat

This thesis presents a body of work on the theme of millimetre-wave FMCW radar, for the purposes of security screening and remote sensing. First, the development of an optimised software radar signal processor will be outlined. Through use of threading and GPU acceleration, high data processing rates were achieved using standard PC hardware. The flexibility of this approach, compared to specialised hardware (e.g. DSP, FPGA etc…), allowed the processor to be rapidly adapted and has produced a significant performance increase in a number of advanced real-time radar systems.

Millimetre wave radar promises to revolutionise the application of radar in the military setting which will lead to a corresponding change to how electronic warfare (EW) systems are applied.

Furthermore, the prevalence of unmanned and autonomous systems will see this type of sensor applied to dynamic and distributed scenarios.

Abstract:

This PhD thesis focuses on quantifying the impact of oscillator phase noise on the design of MMW CW radar systems with the goal of optimising the system to achieve better target detection and tracking. Phase noise in the transmitters of radar systems is known to distort the target response by broadening the linewidth and raising the noise floor of radar systems when a strong scatterer is present in the scene, hence degrading the detection and tracking performance. The situation is worse when multiple large scatterers are present, as the noise sidebands of all scatterers superimpose causing sma

Radar system development is generally costly, complicated and time consuming. This has kept its presence mostly inside industries and research centers with the necessary equipment to produce and operate such a system. Until recent years, realization of a fully integrated radar system on a chip was not feasible, however this is no longer the case and there are several types of sensors available from different manufacturers. Radar sensors offer some advantages that are unmatched by other sensing and imaging technologies such as operation in fog, dust and over long distances. This makes them suit

In this paper, a new millimeter wave 3D imaging radar is proposed. The user just needs to move the radar along a circular track, and high resolution 3D imaging can be generated. The proposed radar uses the movement of itself to synthesize a large aperture in both the azimuth and elevation directions. It can utilize inverse Radon transform to resolve 3D imaging. To improve the sensing result, the compressed sensing approach is further investigated. The simulation and experimental result further illustrated the design.

In the last decade, microwave and millimeter-wave systems have gained importance in civil and security applications. Due to an increasing maturity and availability of circuits and components, these systems are getting more compact while being less expensive.

Due to the ill-posed character of the inverse problem, these algorithms are, in general, very sensitive to noise: the key to their successful application to experimental data is the precision of the measuremen

Abstract:

Avec l’expansion des exploitations agricoles, le principe d’homogénéité du rendement (céréales, fruits…) devient de moins en moins pertinent. Ce phénomène de variabilité spatiale implique des conséquences économiques et environnementales avec le développement de nouveaux concepts agricoles comme les « site-specific management » (gestion spécifique des parcelles). Les traitements tels que les fertilisants, les intrants et autres pesticides doivent être utilisés de manière différente en les appliquant au bon endroit, à la bonne période et au bon taux. Cette nouvelle façon de penser l’agriculture

Abstract:

L’augmentation constante du nombre de capteurs dans les voitures modernes, assurant desfonctions d’assistance à la conduite, font du radar automobile un élément essentiel de la voitured’aujourd’hui et de demain. Cette tendance contribue à plus long terme au développement duvéhicule autonome. L’industrie automobile considère un changement du standard radar actuelà 80 GHz vers une nouvelle bande de fréquence autour de 140 GHz. Ce saut en fréquencepermettrait de réaliser des capteurs plus compact tout en maintenant voir en améliorant laprécision du capteur, grâce aux applications MIMO notamment.

Abstract:

Le développement des radars automobiles, à la bande de fréquences 76-77 GHz, a connu une croissance importante au cours de la dernière décennie. Les développements en cours doivent faire face à deux grands défis. Le premier défi est la réduction du coût pour équiper plus de catégories de voitures avec ces radars. Le deuxième défi est l'amélioration des performances du radar afin de satisfaire les demandes croissantes des autorités de sécurité routière et d'équiper la voiture autonome. L'émetteur-récepteur radar automobile constitue le cœur du système. Par conséquent, une pression importante es

Abstract:

This paper presents the design and characterization of a 28GHz integrated super-regenerative amplifier (SRA) in a 45 nm silicon on insulator (SOI) technology. The circuit is based on a complementary cross-coupled oscillator topology. The fabricated integrated circuit (IC) occupies an area of 0.67 mm 2 , and operates in a frequency range from 28.07GHz to 29.35 GHz. Characterization results show the minimum input sensitivity of the circuit, as -85 dBm and the input power level corresponding to the linear to logarithmic mode transition as -66.3 dBm. The measured output power delivered into a 100

Abstract:

Les radars millimétriques en bande W (75-110 GHz) sont en plein essor, grâce notamment aux progrès des circuits intégrés, permettant de réaliser des systèmes compacts à bas coût et haute résolution due à la courte longueur d’onde. Dans un premier temps, ces systèmes ont été utilisés à des fins de détection et de localisation, avec à terme, pour objectif l’identification. Ainsi, des systèmes d’imagerie radar ont été développés, notamment grâce à l’imagerie qualitative, basée par exemple sur l’imagerie radar par synthèse d’ouverture (SAR). Cependant, afin de reconstruire les propriétés électroma

Abstract:

L’amélioration de la sécurité routière ainsi que le développement des systèmes de transports intelligents sont des enjeux d’avenir dans le secteur automobile avec un essor considérable du véhicule semi autonome et autonome. Les systèmes de sécurité active qui équipent de plus en plus les véhicules commercialisés utilisent des capteurs radar (longue et courte portée) fonctionnant dans les bandes 24 GHz ou 77 GHz. L’étude et la mise au point de tels capteurs peuvent être facilitées via l’utilisation d’une plate-forme de simulation générique permettant de simuler un système radar couplé à son env
