| Abstract: | This paper analyzes the image model of synthetic aperture radar(SAR)and Wigner-Villedistribution(WVD).And WVD is applied in getting the doppler parameters of moving targets in SAR.The properties of cross tems of WVD are discussed.In order to get the porameters effectively,the method of time averaging is used to suppress the cross terms in the condition of multimoving targets.The results ofsimulation validate the effectiveness of the method of time averaging and the possibility of using WVD inacquiring the parameters of moving targets in SAR. |
