摘　　要：为改善弹目动态交会场景下空中目标电磁散射特性仿真时间长、效率低的现象,本文采用基于统一计算设备架构(Compute Unified Device Architecture,CUDA)编程,基于物理光学法和物理绕射理论的并行计算方法对空中目标电磁散射特性进行计算,通过与标准体、某复杂目标的电磁散射结果作对比,验证了算法的准确性,通过对比串行和并行用时,给出本文方法的并行加速比,结果表明并行计算方法可以有效改善仿真效率,获得了较好的加速效果。In order to improve the phenomenon that the simulation of electromagnetic scattering characteristics of air targets in dynamic rendezvous scenarios requires a large amount of calculation and takes a long time,this paper used Compute Unified Device Architecture to construct a parallel calculation method based on physical optics and physical theory of diffraction to calculate the scattering characteristics of targets.The accuracy of the algorithm is verified by comparing with the electromagnetic scattering results of standard bodies and a complex target.The parallel acceleration ration of the simulation is given,and the results show that the parallel calculation method can effectively improve the simulation efficiency and obtain a good acceleration effect.
