Very high resolution (VHR) SAR image simulation for buildings

doi:10.7523/j.issn.2095-6134.2018.06.010

Abstract

Abstract: In this study a very high resolution SAR (VHR SAR) simulation method is proposed based on the geometrical signatures of buildings. Firstly, the imaging scene model is constructed,and an improved Phong Shading model is used as approximate scattering model. Then, the scattering and coordinate information is obtained by tracing rays in the scene. To make the simulation images more realistic, a post process is completed. Finally, a real VHR SAR building image is obtained by two-dimensional imaging. Analysis and simulation results validate that the proposed method describes the geometrical and radiant signatures correctly and efficiently in SAR image. The simulated images provide effective database for understanding SAR images.

Key words: SAR images, image simulation, geometrical signature, ray tracing
