TDOA定位系统的无线电监测网工程应用探讨

随着无线电监测事业的发展，在如何扩大无线电监测网的覆盖范围，提升监测能力等方面越来越得到无线电监测人员的重视，文中主要探讨了TDOA无源定位方法在无线电监测网中的应用问题。本文首先从TDOA定位原理入手，介绍了到达时间差估计的相关函数获取法，比较了双曲线方程组的两种求解算法，由此分析TDOA定位的关键技术与定位优点。文中还以云南省无线电监测网为例，从定位流程出发，进行系统设计，探讨TDOA定位系统的工程应用，进而提出能全面提升监测网监测能力的TDOA定位方案。

Discussion on the application of TDOA positioning system in radio monitoring network

With thedevelopment of the cause of radio monitoring,on how to expand the coverage of radio monitoring network,enhance the ability to monitor etc.more and more attention of the radio monitoring personnel,in this paper mainly discusses the TDOA passive location method in radio monitoring network application problem. Firstly from the principle of TDOA location of the time difference of arrival estimation of correlation function method to obtain, compared the two algorithms for hyperbolic equations.Thus the analysis of TDOA location key technology and location advantages. In this paper also in radio monitoring network of Yunnan Province as an example,from the positioning process of system design, engineering application research of TDOA location system,and then put forward to enhance the monitoring network capability of TDOA positioning scheme.
