Moving Target Detection Based on Azimuth Multi-Channel SAR in Staggered Mode

Moving target detection in the multi-channel staggered SAR system has always been a problem in the field of high-resolution wide-swath imaging. This paper combines the azimuth multi-channel approach with the staggered SAR system, and utilizes DPCA processing to eliminate stationary targets and extract moving targets. The goal is to enhance image resolution further, combining the capability to detect moving targets with high-resolution wide-swath imaging while achieving gapless observation. Simulation results have demonstrated the effectiveness of the proposed algorithm for moving target detection in the high-resolution wide-swath system.
