摘　　要：随着现代社会科学技术的飞速发展,电子通信系统和设备数量也逐渐增多,电磁环境也变得日益复杂,电磁干扰问题越来越严重,现已成为电子通信设备和系统正常工作中的突出障碍。本文针对电磁兼容预分析方法中存在的问题,采用"路"的角度对电子设备或系统抗电磁干扰效能进行分析、仿真,通过对电子设备或系统在不同电磁干扰情况下的各个组成部分仿真实验,从仿真结果可以看出,在卡塞格伦系统中,遮挡效应发生时,处于副反射面的中心位置场强幅度最小,为系统电磁加固和提高抗电磁干扰能力提供更充分的仿真依据。With the rapid development of science and technology in modem society, the number of electronic communication systems and equipment has gradually increased, and the performance will be increased, at the same time, the electromagnetic environment is becoming increasingly complex, the problem of electromagnetic interference is more and more serious, has become a prominent obstacle to electronic communication equipment and the normal work of the system in the. Aiming at the problems existing in the pre analysis method of electromagnetic compatibility, the ＂road＂ is analyzed and simulated the performance of anti electromagnetic interference of electronic＇, e- quipment or system, through simulation experiments on the part of the electronic equipment or system in various different electromagnetic interference, can be seen from the simulation results, in the Cassegrain system, shielding the effect occurs in sub reflector center field amplitude minimum, provide simulation basis more fully to reinforce and improve the ability of anti electromagnetic interference electromagnetic system.
