An Algorithm of Airborne Dual-channel Curvilinear SAR Ground Moving Target Indication

摘要

Traditional dual-channel Synthetic Aperture Radar (SAR) system can detect moving targets, but it can not estimate the location and velocity of moving target. To solve this problem, a method of dualchannel Curvilinear SAR (CSAR) system is presented. From the spatial geometry model and echo signal of the system, the theory of clutter suppression, moving target detection and parameter estimation is derived in detail. Finally, computer simulation results validate its effectiveness.
