卫星通信系统中同频干扰定位方法研究
|
摘要
当前卫星通信应用甚广,C/Ku频段地球静止轨道资源及卫星频段频率资源日益紧张,卫星信号干扰事件不断发生,对干扰信号进行定位并消除干扰则尤为重要。为快速排查干扰,维护用频秩序,合理利用紧缺资源,本文基于地球静止轨道卫星干扰信号的上行站的定位原理,结合实际情况,对同频干扰的上行站定位问题进行深入研究,提出了解决定位同频干扰上行站难点的两种方法并分析了这两种方法的特点和应用优势,结合实际应用案例分析,进一步验证了这两种方法的准确性和高效性,对今后开展卫星干扰定位工作具有很大的帮助。
At present,satellite communications are widely used. The C/Ku band geostationary orbit resources and satellite frequency resources are increasingly strained,and satellite signal interference events keep happening. It is particularly important to locate and eliminate interference signals. For rapid locate interference,maintaining the order of frequency and rational utilization of scarce resources,this article is based on geostationary satellite uplink station positioning principle of interference signal,combined with the actual,situation of uplink station location problem of same frequency interference in-depth study,put forward to solve positioning with frequency interference uplink station the difficulty of the two methods and analyzed the characteristics and application advantages of the two methods,combined with the practical application case,further verify the accuracy and efficiency of these two methods,satellite interference localization work for the future of great help.
