Abstract: We present a technique for multi-path electromagnetic（EM）scattering modeling between targets and background.Based on radar cross section（RCS）calculating methods of high-frequency,by combining a multipath model with the forward complex reflecting coefficient model of rough ground,the radar signature of complex targets on the ground（including 1-D range profiles and 2-D SAR images）are studied.By comparing the 1-D range profiles with 2-D SAR images simulated in direct-path and multi-path scattering,the influence of multipath to the scattering of targets are analyzed.The experiments based on simulation data validate the proposed method.
