针对物理光学（PO：PhysicOptics）方法对复杂目标进行仿真时回波数据生成阶段耗时过长的问题，利用图形处理单元（GPU：GraphicalProcessingUnit）的高度并行性来加速回波生成过程。仿真结果表明：其回波生成过程比在CPU上执行加速了近10倍，从而大大节约了时间。

It is time-consuming to use physical optics method to simulate complex target in the stage of echo data generation. This pa- per, aiming at solving the problem, uses the highly parallel graphics processing unit to speed up the echo generation process. The simu- lation results show that the echo generation process accelerates nearly 10 times compared with that on the CPU, thus saving time.
