Abstract :
The SAR/ISAR imaging of multiple moving targets based on the combination of the Wigner-Ville distribution (WVD) and the Hough transform (HT) is studied. Firstly the WVD and the HT of a multicomponent signal are analyzed. Then an algorithm for detection, parameter estimation and motion compensation is presented. Finally the results of the simulated experiments with a computer and a microwave anechoic chamber are given. It shows that the new method can suppress cross-terms and white noise to improve the detectability and the estimation accuracy of multiple moving targets
