空气中被动声定位系统定位精度分析

Accuracy analysis of passive acoustic locating system in air

本文对影响被动声定位系统定位精度的几种因素进行了比较全面及深入的分析．推导出了测时差定位系统在均匀煤质和非均匀煤质中一些因素对定位精度影响的公式；给出了误差曲线；得出了一些有益的结论并提出了提高定位精度的几种方法．

In this paper, the error sources of a passive acoustic locating system are analyzed. Formulae for the location errors are deduced for the locating system which is based on the principle of measuring the time difference between homogeneous and non-homogeneous media. Some useful conclusions and ways of improving the accuracy are proposed.
