二维匹配滤波实现多角度SAR成像
Multi-Aspect SAR Imaging Using 2-D Matched Filtering
摘要
Abstract
Multi-aspect SAR imaging provide persistent coverage and maximal diversity in the viewing angle about the target feature,it is valuable for SAR ATR.There are two troubles for multi-aspect SAR imaging. One is the imaging focusing;the other is the discontinuity of sampling.In this paper,a 2-D matched filtering method is proposed for multi-aspect SAR imaging.This method forms 2-D matched function by adjusting the reference point, it resolves the focusing and discontinuity sampling problem, it also is applicable for other non-uniformly sampling data.Numerical simulations verify that multi-aspect SAR imaging offers great potential for better resolution over classical radar,it can also representation target feature of different sensor-target orientation.关键词
