This method is an alternative to the correlation-spectral techniques used for ISAR signal processing. This computational technique is based on minimizing the mean square error in the approximation of the quadrate ISAR signal amplitude. An analytical expression of the quadrate amplitude of the ISAR signal, reflected by an object moving in a rectilinear trajectory in the ISAR pattern, is derived. The computational MMSE parameter extraction procedure is structured. The vector of the evaluated invariant parameters is defined. Analytical expressions for determining the elements of the matrixes from the calculating procedure are obtained. A simulation experiment proving the efficiency of the developed algorithm is performed. The MMSE method reveals the possibility for direct reconstruction of the object's geometry in the field of values of the invariant geometric parameters. The worked out approximation parameter extraction MMSE technique can be applied for image reconstruction in the theory and practice of inverse aperture synthesis.","PeriodicalId":366998,"journal":{"name":"2001 CIE International Conference on Radar Proceedings (Cat No.01TH8559)","volume":"23 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":"121964581","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 high-resolution polarization target detection scheme is presented based on intense scatterer integration. Because of the intrinsic high-resolution characteristic of the wideband waveform, a one dimensional range profile of a radar target can be obtained. In connection with the target's polarization characteristics, the number and distribution of intense scatterers in the target's echo can be estimated. SCR (signal-to-clutter ratio) can be improved efficiently by integration of these intense scatterers in corresponding resolution cells. Experimental results show that the radar's detection performance can be improved significantly by using the presented algorithm.","PeriodicalId":366998,"journal":{"name":"2001 CIE International Conference on Radar Proceedings (Cat No.01TH8559)","volume":"105 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":"116810287","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 shown that for large time-bandwidth and low range sidelobe (RSL) requirements, a PRN waveform can be selected that will not increase the radar duty, while LFM will always increase the radar duty. For low time-bandwidth product and moderate RSL requirements LFM will generally have less impact on radar duty than PRN. For moderate time-bandwidth product requirements the impact will be scenario dependent and the difference in radar duty may be outweighed by other considerations.","PeriodicalId":366998,"journal":{"name":"2001 CIE International Conference on Radar Proceedings (Cat No.01TH8559)","volume":"38 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":"128210483","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}

However, for a maneuvering target the assumption is not satisfied, as the Doppler frequency has a time variation property. Actually, to obtain the cross-range resolution of dozens of centimeters for the large-scale or medium targets especially for the S or L wave band, where the wavelength is not shorter, the migration through the resolution cell (MTRC) would occur on both fringes of the ISAR imaging. The reason for this migration through the resolution cell is discussed, and a compensating algorithm is proposed.

These sequences have specific aperiodic autocorrelation function that is very useful in the pulse compression radars. For the radar applications it is very important to find an efficient implementation of the corresponding matched filter. It was done by Popovic with relation to a matched filter for the GCL sequences in the general case as well as special cases for P4 and Frank (1963) codes. The essence of this filter implementation is using the fast Fourier transform (FFT). The synthesis of the filter for a more general GCL model signal and the special cases of P4 and Frank models have been performed. The improvement of the filter efficiency was achieved by implementation of the Fourier transform calculation in a moving window (MDFT).","PeriodicalId":366998,"journal":{"name":"2001 CIE International Conference on Radar Proceedings (Cat No.01TH8559)","volume":"9 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":"130631009","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}
