摘要
对于某些装配有高灵敏度设备的卫星,其舱内设备的非期望辐射发射通过穿舱电缆、过孔等耦合到舱外,被高灵敏度设备在卫星舱外的天线接收,可能干扰高灵敏度设备对正常信号的接收。文章提出了抑制卫星穿舱电缆电磁泄漏的包覆及过孔封堵的方案,同时进行了包覆方法研究和效果分析,验证了该方案可以减小穿舱电缆和穿舱孔的电磁辐射泄漏对接收系统的影响,使卫星的电磁兼容性得到改善。
For a spacecraft installed with high sensitivity equipment,the accidental radiation of theequipment inside the cabin,coupled with that outside the spacecraft cabin through the cable and through the hole,can be received by the high sensitive equipment antenna outside the spacecraft cabin.The reception of thenormal signal by the high sensitive device is disturbed in this case.In view of this situation,a new method ofcable coating and hole plugging is presented to reduce the influence of electromagnetic radiation leakage on thereceiving system.It is shown that the method improves the EMC of the satellite.
