Abstract

The localization and velocity estimation in both ground range direction and azimuth direction was realized by approach of combining DPCA technique with fractional Fourier transform (FrFT) in two aperture radar system. A moving point target echo model of two aperture SAR system was established and linear frequency modulated characteristics of the moving target DPCA signal was elaborated. On the basis of this property, FrFT was adopted to detect moving target and estimate parameters. Because of good capability of DPCA technique for clutter cancellation and nice effect of FrFT for chirp signal detection, simulation results show that the proposed DPCA-FrFT algorithm can suppress clutter and achieve localization and velocity estimation in different SNR conditions effectively.
