摘 要:针对卫星通信系统频带内互调干扰的定位问题进行研究,分析互调干扰产生机理,并给出系统内互调干扰定位方法。定量分析互调干扰频谱特性,并结合频谱管控站分配各站频率,建立系统内各站频率及频差动态数据库,设计基于频差的卫星通信互调干扰源定位方法,精确定位干扰站。仿真结果验证了该方案在互调干扰定位过程的可行性,有效降低了干扰定位时间并提升了准确定位干扰站的概率,为卫星通信系统面临此类干扰时的快速定位提供解决方法,对卫星通信网的稳定运行具有较大实际意义。In this paper,the location problem of intermodulation interference in satellite communication system is studied.The mechanism of intermodulation interference is analyzed,and the location method of intermodulation interference is given.Based on the quantitative analysis of intermodulation interference spectrum characteristics and the frequency allocation of each station by spectrum control station,a dynamic database of each station frequency and frequency difference in the system is established.An intermodulation interference source location method based on frequency difference is designed to accurately locate the inter‐ference stations.The simulation results verify the feasibility of the proposed scheme in the intermodulation interference position‐ing process,effectively reduce the time of disturbance positioning and improve the probability of accurate positioning of the dis‐turbance station,which provides a solution for the rapid positioning of the satellite communication system in the face of such in‐terference,and has great practical significance for the stable operation of the satellite communication network.
