In ISLA the STAP is more complex than that in a sideways looking array (SLA), which is the particular case that these two axes are identical. After analyzing the characteristics of the clutter spectrum in ISLA, the principle of reduced rank STAP based on prefiltering is proposed and discussed.

Furthermore, multi-target situations with up to 10 targets inside a single CFAR window may occur when driving on routes and highways. In this paper the performance of an OS CFAR method is described, applied in an FMCW radar based automotive intelligent cruise control (AICC) system. It is shown that for the applied frequency coded type of waveform OS CFAR is a powerful technique to ensure both reliable detection and very low false alarm rate simultaneously. The applied CFAR procedure can be optimized regarding the required low computational complexity. Theoretical and practical results are presented.","PeriodicalId":144063,"journal":{"name":"Proceedings of International Radar Conference","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114781558","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 comparison of the amplitude histograms with the K and lognormal distribution shows that VV data exhibit a K behaviour, while HH data are better fitted by a lognormal model and cross-polarised data by a K plus thermal noise model. The results have been confirmed by comparing the first four moments and through a modified version of the Kolmogoroff-Smirnoff test. The validity of the compound model, that identifies two components of clutter fluctuations, has been proved for the VV polarisation. The texture component, deriving from the spatially varying mean level has been isolated, since the speckle component was decorrelated by the frequency agility. These results are of great importance for design of optimum target detection schemes.","PeriodicalId":144063,"journal":{"name":"Proceedings of International Radar Conference","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134429063","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}

One is from the projectional information introduced from computer-aided tomography (CAT) founded on the projection-slice theorem. By quoting the concept \"projection\" from CAT to microwave imaging, the spotlight mode SAR can be interpreted as a narrow band tomography reconstruction problem in the far field and small rotation angle situation. Another kind of modeling in the spotlight mode SAR comes from the conventional stripmap SAR directly, in which the processed echo returns are verified to have the same Fourier information as that in the first way. From these two points of view, the spotlight mode SAR can be unified to the problem of Fourier reconstruction (FR). A common problem motion through resolution cells (MTRC) caused by relative rotation in spotlight SAR is characterized as a main factor in imaging smearing or defocusing. Data polar formatting is adopted as an effective solution either of data reconstruction or phase focusing.","PeriodicalId":144063,"journal":{"name":"Proceedings of International Radar Conference","volume":"197 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126055924","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}
