摘要：

This paper uses ray tracing technique to simulate a complete imaging process of Synthetic Aperture Radar (SAR). The simulator can collect the raw data and generate accurate shadows of the object. The radiation pattern is defined by a spotlight to have more realistic imaging effect. Considering the high performance computing of modern graphics processing units (GPU), we transfer the ray tracing algorithm from CPU to GPU. Thus, the simulator can work on a large 3D scene with relatively high efficiency.
