摘　　要：总结了微波接力通信站对卫星通信地球站的同频干扰的计算步骤和方法。首先计算地球站的工作方位和仰角,分析地球站和微波站的相对位置关系;然后,在得到卫星站和微波站相互间的干扰鉴别角的基础上,分别计算两站在干扰方向的天线增益;最后,计算卫星站接收机输入端的干扰信号允许电平和实际的干扰信号电平,通过对比两者的关系,可以判断预选站址是否符合卫星站电磁环境要求。This paper summarizes the calculation process and method of interference that microwave station to SATCOM earth station.Firstly the azimuth and elevation of earth station is worked out,and,the ubiety between earth station and microwave station is analyzed.Then calculation is done for the gain of antenna of two station in interfering direction.Finally allowable interfering signal and actual interfering signal on input port of the receiver of earth station are computed.The results of comparing the value of two signal can estimate whether the preelection point of station is satisfied.
