摘要
介绍了到达时差无源定位的基本方法,以四站定位为例,具体分析了到达时差无源定位精度问题,并通过计算机仿真给出了几种典型布站情况下几何精度因子分布图。
This paper introduces the basic method of time difference of arrival（TDOA）passive location,taking the four-station location as a case,analyses the location accuracy of TDOA,and presents the geometric dimtion of precission（GDOP） in several special station layout through computer simulation.
