MIMO technique is an already well studied method for communications applications thanks to the benefits that it offers in multipath fading environments. This paper is aimed to present the design of a new MIMO based, short range, surveillance radar for local area security purpose. One of the main addressed features to the system under consideration is the capability to provide full 360° azimuth coverage within its working area.

The tile is a modular building block for light weight, high performance phased arrays to be used in space based radar applications. Each tile contains 6 radiating elements with a maximum radiated power per element of ~ 2 W. Each tile includes two beamformers and two T/R modules per radiating element so that any transmit polarization may be formed and both V and H polarizations may be received. Each tile weighs 0.41 kg (3.9 kg/m²). In order to minimize production cost the tile is designed to be fabricated on an industry standard Printed Circuit Board assembly line and the T/R modules are packaged as Plastic Encapsulated Modules (PEMs).

However, some scenarios present great dynamical perturbations regarding positions and velocities, increasing the angular uncertainty window of the received signal's DoA (Direction of Arrival). Some of these scenarios include LEOP (Launch and Early Orbit Phase), orbital maneuvers, on board problems, etc., where TT&C (Telemetry, Tracking & Command) becomes critical. Thus, fast acquisition and appropriate tracking are important processes that must be carefully designed. In this paper it will be shown how a new concept of ground segment station based on distributed arrays of antennae and digital signal processing can improve signal acquisition's convergence speed at low cost, due to the super-resolution capabilities of adaptive DoA estimation algorithms such as MUSIC (MUltiple SIgnal Classification).","PeriodicalId":125604,"journal":{"name":"2010 IEEE International Symposium on Phased Array Systems and Technology","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125875034","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The TWA is fundamentally different from the other two 2-D broadband phased arrays: Current Sheet Antenna (CSA) and Fragmented Aperture (FA). TWA arose directly from antenna concept with an inherent ground plane, while CSA and FA evolved from scattering technology. TWA is much thinner and lighter than CSA and FA, roughly by a factor o 5 and 15, respectively. This study employs an empirical design approach based on the technique of Active Element Gain Pattern (AEGP). Measured data showed TWA's potential for broad bandwidth and wide-angle scan. Some controversies on AEGP in the literature are also clarified.","PeriodicalId":125604,"journal":{"name":"2010 IEEE International Symposium on Phased Array Systems and Technology","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132075318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The features of the UTD-based algorithm in this solver is gainfully utilized to calculate the embedded element pattern of a 5×5 cylindrical dipole element array located before a PEC circular cylinder of electrical radius ka = 96.5. The central element of the dipole array which is kept at 0.257λ off the curved surface of the cylinder, is excited with other dipoles terminated in a matched load of 50Ω. Since NECBSC formally does not calculate the array mutual coupling, this is included by calculating the induced currents on the elements derived from a full-wave integral equation based solver, FEKO. Comparison against the available experimental data shows remarkably good agreement between NECBSC, FEKO in the lit regions. The FEKO and NECBSC yield different results in the deep shadow regions dominated by creeping waves, indicating the necessity of further investigations.","PeriodicalId":125604,"journal":{"name":"2010 IEEE International Symposium on Phased Array Systems and Technology","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130807139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
