Research on Parallel Computing Methods for Air Targets’ Electromagnetic Scattering Based on Missile-Target Encounter

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.
