中文说明：在无线定位系统中，采用基于测量时间信号的定位方法首先要求基站的接收机能从无线电磁波测量信号中精准的得到到达时间值。而TDOA参数测量值的获取主要有以下两种方法：
English Description：
In the wireless positioning system, the positioning method based on the measured time signal requires the receiver of the base station to get the time of arrival accurately from the measured signal of the wireless electromagnetic wave. There are two methods to obtain the measured values of TDOA parameters
