摘要
针对四站时差定位系统求解非线性方程组出现的模糊问题,从定位效能、布站优化、先验信息提取方面进行综合考虑,分析了消除模糊值的3种方式,并通过工程项目的仿真分析,得到一种时差定位系统的最优配置方式。
Aiming at the problem that ambiguity may occur while using 4-station time difference of arrival(TDOA)positioning system to resolve non-linear equations,this paper synthetically considers the positioning efficiency,station distribution optimization,extraction of transcendental information,analyzes three ways to eliminate ambiguity,and fetches an optimal configuration mode of TDOA positioning system through simulating and analyzing the engineering project.
