摘要/Abstract

摘要： 在无线电通信中,干扰信号已经变成当前一个巨大的隐忧。无线电监测部门准确地查找和排除干扰源以确保通信畅通显得尤为重要。对无线电监测中干扰源定位难题做了全面的研究。首先给出了两种已经存在的定位算法:布朗最小二乘三角定位和虚拟力迭代法,然后提出了一种新的方法:基于方位角和网络拓扑的定位算法。通过在实际运用中比较这3种干扰源定位方法的定位精度,发现基于方位角和网络拓扑的定位算法在实际应用中定位干扰源精确度更高。

Abstract: In wireless communication,interference sources have become a huge concern recently．How to search and eliminate precisely is very important so as to restore the network communication for radio monitoring department．In this paper,we took a rounded study on the interference source localization problem in radio monitoring．First introduced two existent localization algorithms,Brown Least-square Triangle Localization and Virtual Force Iterative Localization．Then presented an algorithm,the localization algorithm which is based on azimuth angle and network topology．We compared the localization accuracy with three interference source localization algorithms through simulation and experiments,and found that the localization algorithm which is based on azimuth angle and network topology has higher accuracy in the actual interference source localization.

Key words: Interference source,Localization,Radio monitoring,Azimuth angle,Network topology
