Summary:On the basis of deep analysis of DPCA technique and FrFT, the DPCA-FrFT algorithm which can realize detection and parameter estimations of moving target for three-channel SAR-GMTI system, is presented in this paper. Because of the good capability of DPCA technique for clutter cancellation and the nice attribute of FrFT for LFM signal detection, the DPCA-FrFT algorithm can suppress the clutter and realize the localization and velocity estimations well in different SCR conditions. The simulation results validate the effectiveness of this algorithm.
