Parameter Estimations Based on DPCA-FrFT Algorithm for Three-channel SAR-GMTI System

摘要：

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 DPCAFrFT 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.
