title = "Parameter estimations of SAR moving target based on DPCA-FrFT algorithm",
abstract = "Thc DPCA-FrFT algorithm is used In this paper to realize the localization and velocity estimations in both ground range direction and azimuth direction when It comes to a two-apcrturc radar system. The moving point target's echo model of two-aperture SAR system is established. Then, the linear frequency-modulated characteristics of moving target's DPCA signal is elaborated. According to this characteristics, fractional Fourier transform is adopted to detect the moving target and estimate parameters. Because of the good capability of DPCA technique for clutter cancellation and the nice effect of FrFT for chirp signal detection, the DPCA-FrFT algorithm can suppress the clutter and realize the localization and velocity estimations well In different signal-to-noise ratio conditions. The simulation results validate the effectiveness of this algorithm.",
