The approach of moving targets detection based on conventional dual-channel spaceborne Synthetic Aperture Radar with Displaced Phase Center Antenna(SAR-DPCA) is analyzed. The characteristic of Doppler frequency has been reanalyzed based on slant range coordinate, and the disadvantages of the former method have been presented. The technique based on the motion compensation of the platform is provided, which can eliminate the effect on clutter cancellation caused by the movement between the platform and the ground. This approach can improve the performance of moving targets detection based on dual-channel spaceborne SAR-DPCA system greatly.
