Abstract： In this paper, the fast location problem of intermediate frequency forwarding interference in satellite communication system is studied. Firstly, the causes of intermediate frequency forwarding interference are analyzed, and the steps and methods of locating intermediate frequency forwarding interference are given. The intermediate frequency forwarding interference model is established through quantitative analysis, and the frequency deviation database is established based on the operation of satellite ground station in the network. An intermediate frequency forwarding interference location algorithm based on frequency deviation is designed to accurately locate the earth station with forwarding interference. The simulation results verify the feasibility of the algorithm in the process of intermediate frequency forwarding jamming location, it effectively reduce the jamming location time and improve the probability of accurate positioning of jamming station, and provide a solution for the rapid jamming location when the satellite communication system is faced with such interference, which has great practical significance for the stable operation of satellite communication network.
Key words : satellite communication；intermediate frequency forwarding interference；frequency deviation；interference location
