测时差定位系统定位精度分析与最优布站

Location Accuracy Analysis and Optimal Distribution of TOA Difference Location System

给出了测时差定位系统具体的定位公式 ,并对二维目标定位问题进行精度分析、推导 ,并提出最优布站原则。对三维定位问题提出了最优布站的倒“T”形布站 ,并与倒“Y”形布站进行精度比较 。

This paper gives some formulas for TOA difference location system, analyzes the accuracy of 2D target location and provides the optimal distribution principle by derivation. It continues to provide an optimal distribution, the inverted T distribution, for 3D target location, then compares the accuracy of this distribution with that of inverted Y distribution. Finally an optimal distribution principle for 3D target location is given.
