一种网格化的GNSS干扰源定位方法研究

摘要

介绍了网格化GNSS干扰源定位系统的组成、功能及定位方法；重点阐述了系统采用的TDOA定位方法中Chan定位算法的原理；结合实际应用对Chan算法进行了系统的仿真分析；给出了传感器数量、干扰源位置以及系统噪声对定位结果的影响。%This paper introduces the composition ,function and the TDOA positioning method of a grid GNSS interference source localization system This article focuses on the principle of the Chan algorithm ,which is used in the TDOA positioning method Combining with actual example of grid GNSS interference source localization system the algorithm is simulated and analyzed in this paper .Finally we give the results of simulation to show the effects of the number of sensors ,the position of the interference and systematic noise on lo‐calization result .
