Paper Abstract

In this paper we propose an approach to coherent high resolution image simulation of synthetic aperture radar (SAR) that observes natural terrain scenes. The present approach preserves the relative phase information of each individual scatter when it calculates the backscattering from terrain scene objects that composed of some elementary scatters whose scattering model are well investigated. We adopt the Bin Sort algorithm to simulate SAR imaging process; it combines the extinction, attenuation and shadowing effects of all scatters as well as multiple scattering effects of some strong scatters such as tree trunks and main branches. The fractal concept and Lindenmayor system are employed to model the realistic tree structure while other natural objects are constructed based on the ground truth data. As an example, a coherent SAR image for a computer-generated scene that includes trees, grassland, rough land and water area were simulated.
