| 摘 要： | 在无源多站时差定位系统中布站方式对目标的定位精度有直接影响。在实际战场环境中,布站受地形和战术应用的限制,布站方式会出现不规则的现象。本文给出了多站时差定位的精度分析,并以四站时差系统为例,仿真分析了不规则布站条件下定位精度分布的变化,为战场环境下多站系统的布站提供了理论依据。

| Abstract: | The distribution method of passive multi-stations TDOA Location system affects the location precision directly.In the actual battlefield conditions,because of the limit of terrain and the tactical,the distribution is irregular.In this paper,firstly it gives the theoretic precision analysis of the TDOA location system,and then the variety of location precision is analyzed for the irregular distribution 4 stations TDOA location system.The simulation result provides the theory basis. |
