Moving targets imaging is a very difficult problem in synthetic aperture radar (SAR). In this paper, the authors use the Wigner-Ville distribution (WVD) to estimate the parameters of moving targets. But because of the bilinearity of the WVD, cross-terms occur if the WVD is used in multitarget processing. In order to decrease the influence of cross terms and not increase computation loads, we preprocess the information of moving targets before using the WVD. Simulation results show the availability of this method
