Signal-to-clutter ratio is a determining factor for the detection problem. Raising SCR can bring about an improvement. Here, a cascaded detection scheme is presented. The enhancement of SCR at each stage result in the ultimate improvement of detection performance. At first, by exploiting polarization information, the fused and enhanced one-dimensional range profile is obtained. Then the target's detection is transformed to that of scattering points owing to the high resolving property. Finally, a simulation experiment verifies that the ultimate detection performance is improved.","PeriodicalId":366998,"journal":{"name":"2001 CIE International Conference on Radar Proceedings (Cat No.01TH8559)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131426041","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 paper is based on higher-order statistics (HOS). It only requires calculating the slice of higher-order statistics, and eliminates the calculation of multi-dimensional Fourier transforms. Therefore it requires less computational complexity. At the same time, because higher order statistics can greatly suppress the additive Gaussian noise, it possesses improved performance. For comparison purposes, some simulations, adopting the new method and the classical power spectrum estimation respectively, are introduced. The results show that the new method can effectively extract the range and velocity information of a moving object.","PeriodicalId":366998,"journal":{"name":"2001 CIE International Conference on Radar Proceedings (Cat No.01TH8559)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128334719","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}

This method is based on the discrete time domain model of the echo signal. In addition to the usual matched filter used by image reconstruction of SAR, other two filters are used to get responses which have the same shapes as the responses of the first ambiguities. After the outputs of the latter two filters are subtracted from that of the matched filter, we can get a response nearly free of the first ambiguities. Simulation shows that this method is effective. This method is helpful in improving SAR image quality and relaxing the constraints of the pulse repetition frequency (PRF) in SAR system design.","PeriodicalId":366998,"journal":{"name":"2001 CIE International Conference on Radar Proceedings (Cat No.01TH8559)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133141806","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 addition, it does not need to consider the match between eigenvalues and eigenvectors, or to orthogonalize the DFT Hermite eigenvectors.
