FDA-SAR高分辨宽测绘带成像距离解模糊方法
Range Ambiguity Resolving Method for High-Resolution and Wide-Swath Imaging with FDA-SAR
摘要
Abstract
In space-borne synthetic aperture radar (SAR),severe conflicts exists between azimuth high resolution and wide swath due to Doppler and range ambiguity.To solve this problem,a range ambiguity resolving method for high-resolution and wide-swath (HRWS) imaging with frequency diversity array (FDA) SAR is proposed in this paper.Based on the extra degrees-of-freedom in range domain,FDA is capable of distinguishing the range ambiguous signal in spatial frequency domain.The proposed method first separates the range ambiguous signal in spatial frequency domain,and then performs imaging processing separately on different range ambiguous region to achieve HRWS imaging.Simulation results validate the effectiveness of the proposed method.关键词
