| Abstract: | This paper mainly deals with the optimal inteferometric coherence of the residual images in frequency domain in detection and location of moving target with polarimetric SAR. The essential procedure of clutter cancellation in doppler frequency is presented. A novel method for improving the estimated accuracy of the motion parameters is proposed by taking the optimal polarimetric interferometry processing with residual images in frequency domain. Referring to the theory of optimal polarimetric interferometry, the interferometric coherences of the residual images with different polarization are analyzed. Simulation results show the effectiveness of proposed method. |
