At first near field and through the wall propagation effects on electromagnetic waves are adressed then a MIMO frequency signal model is given and the advantages of a MIMO scheme for the complex task of TTW detection is discussed. Then image formation with beamforming processing is derived. Finally, the proposed imaging method is implemented on numerical signals obtained by FDTD computations considering through cinder blocks walls propagation. The obtained images for scenarii with one or two targets are presented.","PeriodicalId":424165,"journal":{"name":"2011 MICROWAVES, RADAR AND REMOTE SENSING SYMPOSIUM","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121746583","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 aim is to reduce size and weight of satellite telecommunication systems without compromising the high unloaded Q required in such applications. A first class of new miniaturized filters is based on ridges arbitrarily located and oriented within a waveguide. The ridges behave as quasi-TEM resonators and allow for pseudo-elliptic filter responses. A second class of very compact waveguide filters employs TM dual-mode cavities as building blocks to generate Nth order filters with N transmission zeros. Two new concepts have then been developed for high-Q bandpass filters with tunable central frequency or bandwidth using RF MEMS. Cantilever MEMS switches are suitably arranged in a rectangular waveguide so as to change either the TE101 mode resonant frequency or the coupling between E-plane filter resonators. Both approaches are shown to yield higher unloaded Q (∼1000) than previous approaches involving RF MEMS along with ridged or conductor-loaded cavities.","PeriodicalId":424165,"journal":{"name":"2011 MICROWAVES, RADAR AND REMOTE SENSING SYMPOSIUM","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122364996","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 track classifier is a decision system, which allows determining whether the sequence of radar detections forming a track comes from the real target, or from other objects generating clutter. Human operator easily distinguishes the real tracks from the false ones; however the automaton of this process is not trivial. There are no unique criteria for distinguishing the real and false tracks. In general, the sequence of detections coming from the real track is more regular, that means there are not rapid changes of parameters of motion. The term \"rapid change\" is not obvious. To determine whether the parameters of motion change rapidly, the fuzzy logic is applied. From this comes the term \"fuzzy logic track classifier\". The results of the investigation are very encouraging. Applying this method, the number of the false tracks has been reduced more than tree times.","PeriodicalId":424165,"journal":{"name":"2011 MICROWAVES, RADAR AND REMOTE SENSING SYMPOSIUM","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123089406","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 problem is split to independent azimuthal orders and reduced to sets of hypersingular and singular integral equations. These equations are solved numerically by the method of discrete singularities (Nystrom method), using interpolation type quadrature formulas. From the solutions of these sets the surface-current components, near field and the far — zone scattering patterns are obtained. The presented method has a guaranteed convergence for an arbitrary non-axially symmetric primary field. This method is applied to the analysis of a paraboloidal reflector antenna with a conical shield designed to reduce the side radiation.","PeriodicalId":424165,"journal":{"name":"2011 MICROWAVES, RADAR AND REMOTE SENSING SYMPOSIUM","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124690272","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}
