摘要
GEO卫星在轨运行期间,面临着复杂的空间自然强电磁环境,环境中的强电磁脉冲将从"前门"和"后门"两种途径耦合进入星内,对卫星的在轨安全运行构成威胁。本文首先介绍了GEO卫星所面临的空间自然强电磁环境,然后分别就孔缝、光学窗口和穿舱管路、线缆这几种典型的后门耦合通道的特点和研究现状进行了介绍,最后对相应的防护措施进行了总结。
GEO satellite faces complex electromagnetic environment during the service,EMP could couple into the satellite by front-door coupling and back-door coupling and then threaten the safe operation of the satellite in orbit.This paper first introduces the electromagnetic environment faced by GEO satellite in the space,and then introduces the characteristics and current research of the typical back-door coupling path which includes the apertures,optical windows,cables and transmission lines crossing the cabin.The corresponding protection methods are summarized in the end.
