In order to eliminate the disadvantage, the time-domain backprojection method based on finite beamwidth processing is proposed in the paper. The processing method is designed to be more physically realistic by accounting for the actual antenna pattern. Simulation results show that depending on the width of the effective beam, the number of processing loops can be reduced by up to 50%, while still maintaining good image quality in terms of the reconstructed target response.","PeriodicalId":424165,"journal":{"name":"2011 MICROWAVES, RADAR AND REMOTE SENSING SYMPOSIUM","volume":"29 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":"122228296","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}

A reasonable cost of the basic building block of the MPAR, i.e. for the Transmit-receive module (TRM), can only be obtained by lowering the peak power to the order of one watt by pulse-compression. Therefore, MPAR systems call for \"long\" transmitted signals, i.e. with high duty cycle, and for low range sidelobes (low PSLR for point targets, low ISLR for distributed targets such as rain) after pulse compression even in the presence of a significant Doppler shift. Moreover, multi parameter radar measurements (such as the real-time estimation of the full scattering matrix) call for the simultaneous transmission of orthogonal signals. To solve these problems, a novel combination of complementary and orthogonal codes is proposed and the pertaining advantages and drawbacks are discussed, in order to select a class of signal to be tested in the desired frame of an European pre-competitive research with an experimental multichannel radar.","PeriodicalId":424165,"journal":{"name":"2011 MICROWAVES, RADAR AND REMOTE SENSING SYMPOSIUM","volume":"26 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":"122157909","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}

In such schemes, using multiple antennas at transmitter and receiver sides provides spatial diversity without need for identifiable transmitters. On the other hand, one of the problems facing such approach arises when transmitters of a single frequency network (SFN) are used as non-cooperative transmitters and resolving the signals of multiple transmitters reflected from multiple targets is not trivial at receiver side. Therefore, in order to obtain the diversity gain of MIMO localization schemes, it is necessary to develop a technique to assign each echo arriving at the receiver to a given transmitter. In this paper, we propose such technique, that addresses such association problem in an efficient manner.","PeriodicalId":424165,"journal":{"name":"2011 MICROWAVES, RADAR AND REMOTE SENSING SYMPOSIUM","volume":"65 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":"128879584","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}
