Motion compensation is approached in two steps: the range alignment and initial phase compensation. The method of cross-correlation alignment combined with peak value alignment is proposed in range alignment and proved to be effective. A dominant scatterer algorithm is used in phase compensation. A PGA autofocus algorithm is tested in ISAR imaging. Finally, an improved CLEAN algorithm is used in ISAR imaging and post-image processing.","PeriodicalId":144063,"journal":{"name":"Proceedings of International Radar Conference","volume":"12 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":"114882813","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}

It is very difficult for the classical analog quadrature detector to satisfy the requirement of a high performance signal processing technique. The solution of this problem is to use the direct sampling of a low IF signal and generate quadrature samples by a digital filter. The performance of a quadrature IF sampling system based on a digital product detector is analyzed. The scheme is designed and the circuit is implemented by using the INMOS A100. The experimental results are tested. Several important problems about the realization are discussed and analyzed. It is shown by the experimental results that the requirement of a high performance signal processing technique can be fully satisfied by the digital quadrature coherent detector.","PeriodicalId":144063,"journal":{"name":"Proceedings of International Radar Conference","volume":"12 2 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":"123683338","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}

We also determine the conditions under which the effects of pitch, roll and yaw motions are negligible and finally we validate the theoretical analysis by presenting and discussing some simulation results.","PeriodicalId":144063,"journal":{"name":"Proceedings of International Radar Conference","volume":"71 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":"127405423","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}

It takes the greatest value of OS and TM local estimations as a global noise power estimation, and it also uses the automatic censoring technique proposed by He You (1994). Under the Swerling II assumption, the analytic expressions of P/sub fa/, P/sub d/ and ADT of OSTMGO are derived. By comparison with other schemes, the results show that the detection performance of OSTMGO is good both in homogeneous background and in nonhomogeneous environments caused by strong interfering targets and clutter edges; particularly in the clutter edges situation, the peak of false alarm rate of OSTMGO decreases an order of magnitude more than that of GOSGO, while the sample sorting time of OSTMGO is less than half of that of OS.","PeriodicalId":144063,"journal":{"name":"Proceedings of International Radar Conference","volume":"1 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":"129997000","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}
