摘要 实现了从目标建模、散射计算到雷达图像仿真的全过程。首先使用Auto-CAD软件对目标建模并进行三角面元离散,采用反方向光学射线追踪技术进行消隐,以物理光学近似理论计算目标的后向散射,最后利用逆合成孔径雷达成像方法得到了目标的雷达仿真图像。球体的计算结果验证了物理光学的正确性,坦克和飞机模型的仿真成像结果与实验结果和CAD模型的对比进一步证实了目标仿真成像系统的有效性。 The methods of radar target modeling, electromagnetic scatter calculation and radar imaging simulation are presented in the paper. Firstly, the object was modeled with triangular element using AutoCAD; secondly, reverse ray tracing technique was used to find object shadow; thirdly, radar scattering character was calculated based on the Physics Optics (PO) theory, and finally a high-resolution ISAR image of the target could be obtained. The PO model is proved to be correct through the example of sphere. The comparison of the simulated and experimental results between the tank and aeroplane model and CAD model indicates that the ISAR imaging simulation system is effective.
