Abstract:
Antenna array pattern synthesis technology plays a vital role in the field of smart antennas. It is well known that the pattern synthesis of homogeneous array is the key topic of pattern synthesis technology. But this technology needs plenty of homogeneous array elements to meet the antenna requirements. So, a novel pattern synthesis technology for sparse array based on the compressed sensing (CS) and low-rank matrix recovery (LRMR) methods is proposed. The proposed technology predominantly includes the design of sparse array, the recovery of homogeneous array, and the synthesis of antenna array pattern. The simulation result shows that an antenna array with low gain and strong directivity can be arbitrarily built by the use of a small amount of sparse array elements and it is useful for the miniaturization and economical efficiency of the antenna system.

Abstract:
Polarized smart antenna array has attracted considerable interest due to its capacity of matched reception or interference suppression for active sensing systems. Existing literature does not take full advantage of the combination of polarization isolation and smart antennas and only focuses on uniform linear array (ULA). In this paper, an innovative synthesis two-dimensional beampattern method with a null that has cross-polarization for polarized planar arrays is proposed in the first stage. This method aims to further enhance the capability of interference suppression whose optimization problem can be solved by second-order conic programming. In the second stage, a new sparse array-optimized method for the polarized antenna array is proposed to reduce the high cost caused by the planar array that is composed of polarized dipole antennas. Numerical examples are provided to demonstrate the advantages of the proposed approach over state-of-the-art methods.

Abstract:
A novel antenna array architecture for low-cost and compact SATCOM mobile terminal is presented. Based on equal-amplitude aperiodic phased array with fewer active chain numbers, it possesses advantages including lower weight, less cost, and higher power efficiency compared to conventional periodic phased arrays. It is implemented with printed patch antenna so that it guarantees compactness. The elements position and dimensions are jointly designed, with an effective sparse array synthesis strategy that takes actual patch antenna design constraint into consideration, to obtain a maximum array aperture efficiency. Executable and practical approach for variable dimension patch antenna designing, including defect substrate element and small scale array, is introduced and utilized to implement proposed sparse array. Full-wave simulation results demonstrate the advantages of proposed array antenna as well as the effectiveness of corresponding design approach.

Abstract:
A sparse substrate integrated waveguide (SIW) slot antenna array and its application on phase scanning are studied in this paper. The genetic algorithm is used to optimize the best arrangement for 8-element and 7-element sparse arrays over an aperture of 4.5λ0. Antenna arrays with feeding networks, for steering the main beam pointing to 0° and −15°, are demonstrated with the SIW technology. The comparison between the sparse array and the conventional uniformly spaced array with the same aperture are presented, which suggest that the same beam width can be obtained with the gain decreased by 0.5 or 1 dBi and the number of element reduced by 2 or 3, respectively. The sparse antenna array with beam scanning ability presented in this paper shows that, while the beam scanning in the range of ±15°, the gain fluctuation is less than 0.3 dBi and the side lobe level is lower than −10 dB.

Abstract:
Reducing system complexity and cost in synthesizing a sparse array antenna design is a challenging task for practical communication systems, such as radar systems and space communication. In this paper, a hybrid technique to synthesize a linear sparse array antenna design is described. This technique is developed using two methods. The first method is a combinatorial approach that applies cyclic difference sets (CDS) integers to significantly reduce the number of antenna elements. The approach and procedure used to apply the new CDS method to configure a linear sparse array, with significant reduction of the spatial antenna dimension, is described. The second method, applied to the array result of the first method, is amplitude tapering using a binomial array approach to reduce the sidelobes level (SLL). The simulation and measurement results of the sample sparse array design showed that the SLL was reduced in comparison to the sparse array design using only the combinatorial CDS method.

Abstract:
Multi-polarized antenna arrays have the ability to provide both the direction and polarization information of the incident signals, which is important in radar, sonar, wireless communication, remote sensing, and so on. In this paper, a diversely polarized linear array of sparsely located but identically oriented tri-polarized vector antennas (VAs) is designed for estimating the direction-of-arrival (DOA) and polarization parameters of the incident signals in the presence of antenna mutual coupling (MC). In order to reduce the inter-VA MC, a new type of sparse array geometry is proposed, wherein the minimum inter-VA spacing is constrained to be no less than one signal wavelength. Considering the intra-VA MC effect, a full-wave electromagnetic simulation is introduced to fit the manifold vector of an isolated VA. Based on the sparse VA array, a polarimetric subspace scheme is proposed for DOA and polarization estimation. When the knowledge about the intra-VA MC is a priori unavailable, an algebraic polarimetric blind scheme is also provided for DOA estimation. Computer simulations and real-world experiments (using an S-band 24-channel tri-polarized array system) validate the efficacy of the designed array geometry along with the parameter estimation methods.

Full text
Abstract:
An adaptive beamforming based on compressed sensing with smoothedl0norm for large-scale sparse receiving array is proposed in this paper. Because of the spatial sparsity of the arriving signal, compressed sensing is applied to sample received signals with a sparse array and reduced channels. The signal of full array is reconstructed by using a compressed sensing reconstruction method based on smoothedl0norm. Then an iterative linearly constrained minimum variance beamforming algorithm is adopted to form antenna beam, whose main lobe is steered to the desired direction and nulls to the directions of interferences. Simulation results and Monte Carlo analysis for linear and planar arrays show that the beam performances of our proposed adaptive beamforming are similar to those of full array antenna.

Abstract:
Broadband antenna arrays have become increasingly popular for various imaging applications, such as radio telescopes and radar, where high sensitivity and resolution are required. High sensitivity requires the development of large scale broadband arrays capable of imaging distant sources at many different wavelengths, in addition to overcoming noise and jamming signals. The design of large scale broadband antenna arrays requires large number antennas, increasing the cost and complexity of the overall system. Moreover, noise sources often vary, depending on their wavelengths and angular locations. This increases the overall design complexity particularly for broadband applications where the performance depends not only on the required bandwidth, but also on the frequency band.This thesis provides a study of broadband antenna array systems for large scale applications. The study investigates different tradeoffs associated with designing such systems and drives a novel design approach to optimize both their cost and performance for a wide range of applications. In addition, the thesis includes measurements of a suitable array to validate the computational predictions. Moreover, the thesis also demonstrates how this study can be utilized to optimize a broadband antenna array system suitable for a low frequency radio telescope.

Abstract:
The objective of this thesis is to investigate the performance of the EISCAT 3D Array antenna for dierent architectures and dierent types of elements. The thesis focuses on the type of element designed by Lulea Technical University and build by GELAB Company. Another objective is to nd the optimum architecture that will make the array meet the requirements of a 3D imaging radar and result in a minimum number of elements for achieving the performance goals set by the specications. The EISCAT 3D Array requires a high number of elements and this implies a high level of interaction between the elements, also known as mutual coupling. In order to simulate the performance of the array including the coupling, a program was written in MATLAB using an element radiation pattern simulated in NEC2. This pattern includes the mutual coupling eects of the single element designed by Lulea Technical University. A method called thinning is applied to reduce the number of elements and, consequently, the coupling. The results show that the thinning parameters change the performance of the array with a xed pattern. Increasing the number of elements, the key performance indicators (Directivity and Side lobe level) show an improvement. It was found that one of the thinning parameters, the design side lobe ratio, has more weight on the indicators. This parameter indicates the maximum level of the side lobe and for increasing values, the Directivity decreases but the Peak Side lobe improves to a higher level. The Average Side lobe level, however, decreases when the design side lobe ratio parameter increases. As a conclusion, it can be said that a thinned array with a circular aperture meets the requirements better than one with a square aperture. The circular aperture leads to improved results (higher Directivity) with less elements. Another important conclusion is that the directivity of the main beam and the side lobe level is strongly dependent on both the azimuthal and elevation angle. In order to fully understand the consequences of mutual coupling and thinning, a more in-depth investigation into all directions in the eld of view needs to be conducted before a nal decision on the element design can be made.

Abstract:
Cette thèse présente la conception, réalisation et mesure d’un réseau d’antennes reconfigurable dans la bande 3,4-3,8 GHz. Le réseau actif est composé de 16 dipôles à double polarisation qui peuvent rayonner un faisceau pouvant dépointer dans un plan sur un secteur angulaire de ±45°. Grâce à l’utilisation d’un générateur de signaux arbitraires, deux faisceaux pointant dans deux directions peuvent être rayonnés simultanément à deux fréquences différentes et reconfigurés à souhait. Ce réseau peut être vu comme un candidat pour de futurs systèmes de communication terrestre. Deux opérateurs mobiles pourraient alors partager le même réseau d’antennes. Les étapes de la conception du réseau sont détaillées progressivement, de l’élément unitaire, vers le réseau passif, puis reconfigurable par paquets, pour finir par le réseau complètement reconfigurable. La conception du réseau a eu pour ligne directrice la réduction de consommation d’énergie. Ainsi, des outils de synthèse ont été développés pour exploiter au mieux les caractéristiques de consommation des amplificateurs utilisés. De nombreux résultats de mesure valident les performances en rayonnement du réseau à chaque étape intermédiaire. De plus, ils montrent la réduction de consommation d’énergie réalisée et valident ainsi expérimentalement l’intérêt pratique des outils de synthèse développés
This thesis is dedicated to the design, manufacturing and characterization of a reconfigurable antenna array in the 3.4-3.8 GHz band. The active array is composed of 16 dual polarized dipoles that are able to radiate a beam steerable from ± 45° in a plane. Thanks to an arbitrary waveform generator, two beams can be radiated in two directions at two different frequencies simultaneously and can be reconfigured at will. This array can be seen as a candidate for future terrestrial communication systems. Two mobile network operators could then share the same antenna array. The steps of the array design are detailed showing the progression from the single antenna, to the passive array, the reconfigurable array by cluster to finish with the fully reconfigurable array. The array design has been driven by the reduction of the energy consumption. For that purpose, array synthesis tools have been developed to leverage at best the consumption characteristics of amplifiers. A number of measurement results validate experimentally the array radiation performances at each step of the design. Moreover, they demonstrate the achieved reduction of energy consumption and thus validate experimentally the practical interest of the developed synthesis tools

Abstract:
Les travaux de cette thèse s’intéressent à un nouveau concept d’antenne reconfigurable offrant un bon compromis entre performances, complexité et coût. Ce concept, qualifié d’hybride, vise à combiner les avantages des réseaux d’antennes lacunaires et des antennes à éléments parasites. Cette hybridation est une alternative à la complexité des réseaux d’antennes conventionnels pour répondre aux exigences d’une architecture modulaire, générique et reconfigurable. L’intérêt majeur de ce concept est de proposer une architecture d’antenne permettant de réduire la complexité du circuit de formation des faisceaux (par la réduction du nombre d’éléments rayonnants à alimenter) tout en adressant les problématiques d’adaptation (TOS actif) des éléments excités. Ceci est permis grâce à la présence d’éléments parasites qui permettent de gérer la diffusion des couplages sur l’antenne. Cette thèse décrit le principe du concept hybride et propose une évaluation de ses potentialités. Par la suite, une définition des éléments à mettre en œuvre pour réaliser une preuve de concept est effectuée, en mettant l’accent sur l’importance de la caractérisation expérimentale. Les performances d’un prototype d’antenne hybride reconfigurable sont ensuite présentées afin de valider les développements et conclure sur cette solution innovante
The work of this thesis aims to investigate a new concept of reconfigurable antenna allowing a good trade-off between performances, complexity and cost. This concept is called ‘hybrid’ because it is based on the capabilities of thinned arrays and parasitic element antennas. It is an alternative to classical antenna arrays and their complexity. The proposed concept has a modular architecture, and a good versatility for reconfigurable beams. The main advantage of this hybrid antenna is the simplicity of its beam formation network (BFN) which requires only a few number of excited elements. The antenna uses parasitic elements to manage the effects of couplings between the electromagnetic access. The problematic of active VSWR is also solved at the antenna level, avoiding the use of additional components in the BFN. This work details the principle of the reconfigurable hybrid antenna concept. The potentialities are evaluated. The elements required to realize a proof of concept are then defined, using a dedicated experimental setup. A prototype is manufactured and the performances have been checked to validate this innovative concept

Abstract:
Cette thèse a pour but d'estimer la position et la puissance de sources sonores ponctuelles à l'aide d'une antenne acoustique. Nous nous intéressons d'abord à la directivité des antennes acoustiques pondérées. On montre qu'une telle antenne, appelée antenne conventionnelle, même si elle est à directivité optimale, est inutilisable pour localiser plusieurs sources sonores. Des traitements adaptatifs d'antenne sont donc exigés et les méthodes dites à haute résolution sont introduites. Elles sont basées sur l'estimation de la matrice de covariance des signaux issus des capteurs et présentent l'avantage de s'affranchir des limitations naturelles du traitement d'antenne conventionnel. Cependant, ces méthodes nécessitent l'emploi d'un modèle de propagation et sont donc par nature peu robustes aux erreurs de modèle, ce qui peut être parfois un handicap et dégrader leurs performances. Par la suite, nous présentons une nouvelle méthode de séparation des sources utilisant une représentation parcimonieuse des signaux. Nous montrons que ses performances sont meilleures que celles obtenues par les méthodes à haute résolution et notre algorithme parvient à une bonne résolution spatiale, même sous des conditions défavorables. Cette méthode est appliquée aux sources corrélées et décorrélées, à bande étroite et à large bande, en champ proche et en champ lointain. Pour finir, nous présentons des méthodes pour estimer la puissance des sources sonores. Des simulations numériques et des expérimentations en chambre anéchoïque sont effectuées afin de vérifier et de valider les analyses et les résultats théoriques

Abstract:
En réponse au nombre toujours élevé de décès provoqués par les accidents routiers, l'industrie automobile a fait de la sécurité un sujet majeur de son activité global. Les radars automobiles qui étaient de simples capteurs pour véhicule de confort, sont devenus des éléments essentiels de la norme de sécurité routière. Le domaine de l’automobile est un domaine très exigent en terme de sécurité et les radars automobiles doivent avoir des performances de détection très élevées et doivent répondre à des nombreuses contraintes telles que la facilité de production et/ou le faible coût. Cette thèse concerne le développement d’algorithmes pour la détection et la localisation de piétons et de cyclistes pour des radars automobiles de nouvelle génération. Nous avons proposé une architecture de réseau d'antennes non uniforme optimale et des méthodes d'estimation spectrale à haute résolution permettant d’estimer avec précision la position angulaire des objets à partir de la direction d'arrivée (DoA) de leur réponse. Ces techniques sont adaptées à l'architecture du réseau d'antennes proposé et les performances sont évaluées à l'aide de données radar automobiles simulées et réelles acquises dans le cadre de scénarios spécifiques. Nous avons également proposé un détecteur de cible de collision, basé sur la décomposition en sous-espaces Doppler, dont l'objectif principal est d'identifier des cibles latérales dont les caractéristiques de trajectoire représentent potentiellement un danger de collision. Une méthode de calcul d'attribut de cible est également développée et un algorithme de classification est proposé pour discriminer les piétons, cyclistes et véhicules. Les différents algorithmes sont évalués et validés à l'aide de données radar automobiles réelles sur plusieurs scenarios
In response to the persistently high number of deaths provoked by road crashes, the automotive industry has promoted safety as a major topic in their global activity. Automotive radars have been transformed from being simple sensors for comfort vehicle, to becoming essential elements of safety standard. The design of new generations automotive radars has to face various constraints and generally proposes a compromise between reliability, robustness, manufacturability, high-performance and low cost. The main objective of this PhD thesis is to design algorithms for the detection and localization of pedestrians and cyclists using new generation automotive radars. We propose an optimal non-uniform antenna array architecture and some high resolution spectral estimation methods to accurately estimate the position of objects from the direction of arrival (DOA) of their responses to the radar. These techniques are adapted to the proposed antenna array architecture and the performance is evaluated using both simulated and real automotive radar data, acquired in the frame of specific scenarios. We propose a collision target detector, based on the orthogonality of angle-Doppler subspaces, whose main goal is to identify lateral targets, whose trajectory features represent potentially a danger of collision. A target attribute calculation method is also developed and classification algorithm is proposed to classify pedestrian, cyclists and vehicles. This classification algorithm is evaluated and validated using real automotive radar data with several scenarios

Abstract:
Les techniques d’identification acoustique visent à caractériser les différentes sources de bruit sur un avion à partir de données microphoniques. Ces techniques nécessitent la connaissance de la fonction de Green acoustique du milieu. Or celle-ci n’est connue analytiquement que pour des configurations simples et l’utilisation de fonctions de Green imparfaites conduit à une erreur sur l’identification des sources. L’objectif de cette thèse est de mettre au point une méthode numérique d’estimation des fonctions de Green pour l’imagerie aéroacoustique. La méthode doit avoir un coût de calcul minimal et fournir une estimation suffisamment précises pour être utilisée dans des configurations réalistes. Pour cela, la parcimonie de la fonction de Green dans le domaine temporel est prise en compte. Il en découle un problème d’identification de système nécessitant l’utilisation d’algorithmes de régression linéaire. La méthode est d’abord validée sur des cas numériques 3D représentatifs de ceux rencontrés dans l’industrie. Lorsque le nombre de points de focalisation est élevé, la réciprocité en écoulement retourné simplifie considérablement le problème. La méthode est ensuite appliquée sur des données d’essais réalisés sur une aile à haute portance passée en soufflerie anéchoïque à veine ouverte justifiant de l’applicabilité de la méthode sur des configurations industrielles réalistes
Acoustic imaging techniques aims at characterizing the different acoustic sources of noise on an aircraft using microphone array measurements. Those techniques require the knowledge of the acoustic Green’s function of the medium. Unfortunately, this function is known only for cases of relatively simple complexity and the use of approximate Green’s function can lead to errors in the identification of the sources. The main aim of this thesis is to set up a numerical method for the estimation of the Green’s function for aeroacoustic imaging applications. The method must have a minimal computational cost and provide a sufficiently accurate estimation to be used on realistic industrial configurations. The proposed methodology takes advantage of the sparsity of the Green’s functions in the time-domain. This results in a system identification problem and sparsity-based regression algorithms can be used to solve it. First, the method is validated on complex 3D numerical test cases typical of those encountered in the industry. For configurations involving a high number of focus points, the reverse-flow reciprocity simplifies significantly the Green’s function estimation problem. The methodology is finally applied on high lift 2D wing data placed in the ONERA CEPRA19 open section anechoic wind tunnel justifying the applicability of the method on realistic industrial configurations

Abstract:
Linear sparse antenna arrays have been widely studied in array processing literature. They belong to the general class of non-uniform linear arrays (NULAs). Sparse arrays need fewer sensor elements than uniform linear arrays (ULAs) to realize a given aperture. Alternately, for a given number of sensors, sparse arrays provide larger apertures and higher degrees of freedom than full arrays (ability to detect more source signals through direction-of-arrival (DOA) estimation). Another advantage of sparse arrays is that they are less affected by mutual coupling compared to ULAs. Different types of linear sparse arrays have been studied in the past. While minimum redundancy arrays (MRAs) and minimum hole arrays (MHAs) existed for more than five decades, other sparse arrays such as nested arrays, co-prime arrays and super-nested arrays have been introduced in the past decade. Subsequent to the introduction of co-prime and nested arrays in the past decade, many modifications, improvements and alternate sensor array configurations have been presented in the literature in the past five years (2015–2020). The use of sparse arrays in future communication systems is promising as they operate with little or no degradation in performance compared to ULAs. In this chapter, various linear sparse arrays have been compared with respect to parameters such as the aperture provided for a given number of sensors, ability to provide large hole-free co-arrays, higher degrees of freedom (DOFs), sharp angular resolutions and susceptibility to mutual coupling. The chapter concludes with a few recommendations and possible future research directions.

Abstract:
Three working modes, omni-, sector and adaptive modes, for a compact array antenna are introduced. The compact array antenna is an electronically steerable parasitic array radiator (Espar) antenna, which has only a single-port output, and carries out signal combination in space by electromagnetic mutual coupling among array elements. These features of the antenna significantly reduce its cost, size, complexity, and power consumption, and make it applicable to mobile user terminals. Signal processing algorithms are developed for the antenna. An omnipattern is given by an equal-voltage single-source power maximization algorithm. Six sector patterns are formed by a single-source power maximization algorithm. Adaptive patterns are obtained by a trained adaptive control algorithm and a blind adaptive control algorithm, respectively. The experiments verified the omnipattern, these six sector patterns and the adaptive patterns. It is hope that understanding of the antenna’s working modes will help researcher for a better design and control of array antennas for mobile user terminals.

Abstract:
Differential Evolution (DE) is a popular evolutionary algorithm that has been applied to several antenna design problems. However, DE is best suited for continuous search spaces. Therefore, in order to apply it to combinatorial optimization problems for antenna design a binary version of the DE algorithm has to be used. In this chapter, the author presents a design technique based on Novel Binary DE (NBDE). The main benefit of NBDE is reserving the DE updating strategy to binary space. This chapter presents results from design cases that include array thinning, phased array design with discrete phase shifters, and conformal array design with discrete excitations based on NBDE.
