一种强杂波背景下 SA R目标超分辨成像方法
Super-resolution imaging method for the SAR target in a strong clutter scene
摘要
Abstract
This paper proposes a super‐resolution imaging method to solve the problem of extracting targets and enhancing resolution under a strong clutter in the SAR image . Based on singal correlation , an adaptive clutter threshold is proposed to extract strong scatterers of targets . Then weak scatterers of targets are extracted by the gradient descent method . Finally , target resolution is enhanced to realize super‐resolution imaging by the simplified regularization method . Real‐measured data of reflectors and the stationary vehicle validate the effectiveness of the proposed method .关键词
