| 摘 要： | 通过对现有的无线网络定位技术(包括网络定位、终端定位、有源定位、无源定位)和各种定位算法(包括具有解析表达式解的算法、递归算法)的深入研究和分析,提出一种高精度的无源定位技术方案。这种定位技术采用无源网络定位模式,同时计算多个TDOA值,由地面定位站根据多个TDOA值解算出位置,以提高定位精度。面对用户对定位精度要求的日益提高,高精度地面无源定位系统将会有广大的市场前景。

| Abstract: | The existing wireless network positioning technology（including network positioning,terminal positioning,active positioning and passive location）and various positioning algorithms（including algorithms with solutions of analytic expressions and recursive algorithm）are researched and analyzed deeply. A scheme of the high-accuracy passive location technology is pre-sented,in which the passive network position mode is adopted to calculate multiple values of TDOA at the same time,and then work out the position by the ground station according to multiple values of TDOA,so as to improve positioning accuracy. |
