摘要
复杂电磁环境下,卫星侦察设备的工作方式都是依赖电磁波的传播,其感知的准确性不同程度地受到电磁干扰的影响.文章从复杂电磁环境的本质出发,重点分析了人为形成的几类电磁干扰,包括对卫星电子侦察、光学成像侦察、雷达成像侦察和卫星导航定位的干扰以及干扰应对措施,为最大限度减少复杂电磁环境对卫星感知的干扰提供了参考.
As the satellite reconnaissance equipment is relied on the electromagnetic wave transmission,its accuracy is affected by the impact of electromagnetic interference(EMI) in various degrees.This paper analyzes the complicated electromagnetic environment,focusing on the effects of several types of artificial electromagnetic interferences on satellite electrical reconnaissance,optical and SAR imaging,and satellite navigation.Some propositions for anti-jamming are given.
