通过分析天通卫星终端产生的二次谐波杂散对C波段卫星固定业务系统下行造成的同频干扰,基于不同的杂散发射限值要求,考虑在不同信道环境中天通卫星终端分布的情况,采用蒙特卡洛仿真方法,比较了卫星地球站天线在不同仰角和不同水平距离条件下天通卫星终端对卫星地球站的干扰情况,并给出了天通卫星终端与C波段卫星地球站兼容共存的相关技术条件和建议。
The co-channel interference caused by the second harmonic spurious emissions from Tiantong satellite terminal to the downlink of C-band satellite fixed service system was analyzed. Based on different spurious emissions requirement limits
considering the distribution of Tiantong satellite terminals in different channel environments
the Monte Carlo simulation method was used to compare the interference condition of Tiantong satellite terminal to satellite earth stations at different elevation angles of satellite earth station antennas and the isolation distance between Tiantong satellite terminal and satellite earth stations. The relevant suggestions were given for the co-existence of Tiantong satellite terminal and C-band satellite earth stations.
