Abstract

In this paper, a novel method is proposed for the imaging of ground moving target with motion error compensation. The Keystone and Hough transform are utilized to correct the Range Cell Migration first. Then the Fractional Fourier transform (FrFT) is adopted to estimate the Doppler parameters of ground moving targets. Finally, moving targets are imaged. The proposed algorithm can accurately estimate the motion parameters and image multiple ground moving targets, which is validated by the simulation results.
