A New Ground Moving Targets Detector in Dual-Channel SAR Images

Concerning ground moving targets detection in dual-channel SAR images,a novel detector based on dual-channel sample covariance matrix is proposed.The method succeeds by checking magnitude and phase variation of off-diagonal elements in sample covariance matrix.Compared with traditional DPCA,it achieves better clutter rejection,eliminates influences from target sidelobes,sets threshold more easily and gets lower Pfa.Simulation results show the effectiveness of the method.
