SAR Imaging of Moving Target Based on Quadratic Phase Function

By Chao Wang and Shaobin Li

Abstract

In this paper, a novel signal processing technique has been 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 mov-ing targets. The simulated results demonstrated the validity of the algorithm proposed
