Interference analysis and research on Tiantong satellite terminal to C-band satellite earth station

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.
