摘要

杂波抑制是实现地面慢速目标检测(GMTI

Ground Moving Target Indication)的前提条件.本文研究基于高分辨合成孔径雷达(SAR

Synthetic Aperture Radar)图像在杂波起伏时地面动目标检测问题.利用沿航迹(along-track)多幅SAR图像的相关性

提出一种基于广义特征分解的联合噪声子空间投影杂波相消算法.理论分析和仿真结果表明该算法在一定程度上能够有效抑制杂波内部起伏

并且对SAR图像配准误差具有稳健性.

Abstract

Clutter suppressing is the prime problem for ground moving target indication(GMTI).We focus on clutter inner undulating which influences the performance of moving target detection.Exploring correlation between along-track synthetic aperture radar (SAR) images

a clutter suppressing algorithm based on joint noise eigen-subspace projection is presented.The robustness for clutter inner undulating and images registration error is proved by subspace analysis and extensive simulation.
