SAR images simulation is very important for SAR image interpretation and target recognition, and the method of SAR
images simulation of ground vehicles is thoroughly studied in this paper. Firstly, the dominant scattering mechanisms of
ground vehicles are analyzed. Secondly the RCS and complex scattering field of targets is computed based on
high-frequency electromagnetic scattering prediction methods of PO and GO etc. And finally, through SAR imaging
processing of the complex scattering field datum, the simulated SAR images are obtained. The performance of the
simulation is evaluated qualitatively and quantitatively by comparing the simulated SAR images with MSTAR measured
ones. And they all show good agreement.
