Abstract

In this paper, a modified SAR simulation method based on three-dimensional electromagnetic model is presented. SAR´s squint working mode and three-dimensional electromagnetic model will cause facing slope reduction and backing slope increases phenomenon. The effect will lead to SAR image distortion and targets position migration. A non-equidistant interpolation algorithm is proposed in the SAR simulation processing, which is applicable to SAR simulation to eliminate the impact of facing slope reduction and backing slope increases. Simulation results have proved that SAR image processed with this SAR simulation method is more close to real scenes.
