Abstract

Abstract

A new method for the motion compensation of multiple moving targets imaging with SAR/ISAR based on Wigner-Ville and Hough transform is presented and studied. The main steps for motion detection, estimation and compensation are given. The simulated experimental results with computer and microwave anechoic chamber show that the new method is effective for suppressing the cross-terms and noise, so it is clear the new method is an improvement on a unitary WVD method, and the new method can be used to improve the detection and estimation capability of single or multiple moving targets in noisy enviroment.
