Research on moving target detection of spaceborne SAR based on STAP and CS algorithm

In this paper, STAP algorithm is further studied based on the theory of CS-based moving target detection in spaceborne SAR, and a method of detecting STAP and CS combined moving target is proposed. This method restores STAR clutter again for target data reconstructed by CS reconstruction algorithm for each distributed satellite. The STAP clutter suppression can detect the moving target position more efficiently. The theoretical and simulation results show that the proposed method can detect the exact position of the moving target. Compared with the traditional CS algorithm, this method has obvious superiority.
