ABSTRACT: In this paper, a novel signal
processing technique hasbeen developed to refocus moving targets image from their smeared
responses in the Synthetic Aperture Radar (SAR) image according to the
characteristics of the received signals for moving targets. Quadratic Phase Function
is introduced to the parameters estimation for moving target echo and SAR
imaging. Our method is available even under a low SNR environment and acquiring
an exact SAR image of moving targets. The simulated results demonstrated the validity of the
algorithm proposed.
