Study on A Robust Slowly Moving Target Detection and Location Algorithm Based on Three-port SAR
一种鲁棒的三通道SAR慢动目标检测、定位算法研究

In this paper, a robust slowly-moving target detection and location algorithm is investigated. In practice, due to channel imbalance such as gain and phase error, the clutter suppression performance of the interferometric SAR/ GMTI is significantly degraded, and makes it difficult to detect and locate the moving target. A channel error calibration algorithm based on sub-patch SAR image is proposed, and the spatial adaptive processing is used for the moving target detection and location.The simulation results are presented to demonstrate that, the proposed algorithm is robust to system errors, and is suitable for engineer implementation.
