However, the convergence rate of this gradient-descent based algorithm is governed by the eigenvalue spread of the autocorrelation matrix. The eigenvalue spread ratio (ESR) in a generalized sidelobe canceller (GSC) is derived. It can provide insight of how various parameters, related to an adaptive array system, affect the performance of the convergence rate. Finally, numerical and simulation results are used to verify that the derivation of ESR is correct.","PeriodicalId":366998,"journal":{"name":"2001 CIE International Conference on Radar Proceedings (Cat No.01TH8559)","volume":"39 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":"116925192","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 modification limits the resolution that one obtains of the observed objects and brings about the need to reverse the convolution and extract a better object description. We examine a deconvolution problem that is restricted in two ways: the first one assumes that two or more diverse sensor outputs for the same scene at the same viewing angle are available; and second one chooses to look for a deconvolution approach which utilizes the sum of linear convolution filters applied to each of these sensor outputs to produce the deconvolved output being sought. We develop a practical approach to finding optimal deconvolution operators via linear programming. The approach is illustrated by application to the problem of radar beam sharpening using a variety of sensor descriptions.","PeriodicalId":366998,"journal":{"name":"2001 CIE International Conference on Radar Proceedings (Cat No.01TH8559)","volume":"66 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":"114880415","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}

Among all the ATPA algorithms, the old-fashioned binary-processing (BP) algorithm is in an almost-obsolete state. Today the most widely used algorithm is the area-center (AC) algorithm. But the centroid algorithm has gained more and more attention because it has better precision and requires simpler data structures. However, all the above algorithms are unable to completely solve the problem of signal expansion in the range dimension, which is caused by pulse-compression techniques. For long-range surveillance radar systems, if this problem remains unresolved, it is impossible to achieve high resolution of azimuth and range. We propose a 2-dimensional centroid algorithm based on the: original centroid algorithm, which is only 1-dimensional. We have also designed a simplified peak-searching (PS) algorithm according to the characteristics of long-range surveillance radar. Analysis and simulation shows that this algorithm has relatively high estimation precision, and its implementation scheme is very easy. It has already been successfully used in a long-range surveillance radar system.","PeriodicalId":366998,"journal":{"name":"2001 CIE International Conference on Radar Proceedings (Cat No.01TH8559)","volume":"50 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":"126523223","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}

Stealth techniques and anti-radiation missiles (ARM) raise challenges to military radar. Many research results show that meter (or much longer) wavelength electromagnetic waves are the right way against the stealth technique and ARMs. However, traditional meter wave radar has many disadvantages, such as poor angle resolution, weakness against ECM, low measurement precision etc. The new concept of synthetic impulse and aperture radar was presented, by J. Dorey et al. (see Colloque International sur le Radar, p.556-62, 1989). SIAR has no scanning mechanism or phased devices. The beams or antenna patterns of both the transmitting array and the receiving array are formed by digital calculation. SIAR can keep the advantages of traditional meter wave radar and overcome most of its disadvantages. This new kind of radar has many other advantages, for example, low probabilities of interception (LPI), capacity of long coherent integration of targets and fine Doppler resolution, high feasibility of system processing, etc. The basic concepts of SIAR and some experimental results are introduced.","PeriodicalId":366998,"journal":{"name":"2001 CIE International Conference on Radar Proceedings (Cat No.01TH8559)","volume":"37 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":"123477669","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}
