| 摘 要： | 对月球探测器的测控通信,通信距离遥远,信号空间损耗大,地面站接收机灵敏度高,因此更易受到外来信号干扰的影响。本文根据卫星网络间同频干扰计算方法,分析月球探测器测控通信下行链路受地球轨道卫星发射信号的干扰问题,主要包括月球探测器受地球静止轨道卫星（GEO）和地球非静止轨道卫星（NGSO）的干扰分析。在此基础上实现了仿真,计算其受干扰的可能性。

| Abstract: | Long communication distance,high propagating attenuation and low permissible interference levels often result in extreme sensitivity of TT&C earth stations for a lunar explorer.With a method for analysis of existing co-frequency interference between satellite networks,this paper studies co-frequency interference on the downlink of a lunar explorer from geostationary satellite and non-geostationary satellite networks.Then,co-frequency interference is simulated and the possibility of interference is computed. |
