大型深空站周边抗电磁干扰对策研究

深空测控活动具有信号空间衰减大、传输时延长、传播环境复杂等特点，电磁干扰对活动影响较大。对某型深空站电磁干扰现状开展分析，区分各类干扰源，对常用的抗电磁干扰对策方法进行研究。以电磁环境监测与管理信息系统为依据来研究电磁环境实时监测在深空站的实现，探索适宜深空站使用的电磁干扰监测方法和抗电磁干扰的对策，并从体制机制上对深空站实施有效保护。

Study on countermeasures against electromagnetic interference around large deep space station

Deep space TT&C(tracking,telemetry and command) activities are characterized by large signal space attenuation,prolonged transmission time and complex propagation environment,and electromagnetic interference has a great influence on the activities.This paper analyzes the electromagnetic interference status of a deep space station,distinguishes various interference sources,and studies the commonly used countermeasures against electromagnetic interference.Based on the electromagnetic environment monitoring and management information system,the realization of real-time electromagnetic environment monitoring in deep space station is studied,and the electromagnetic interference monitoring methods and countermeasures suitable for deep space station are explored,so as to effectively protect the deep space station from the physical mechanism.
