基于鉴相技术的高精度无线定位方法

介绍了利用鉴相器AD9901区分输入鉴相器的两列波的相位差，这种方法是在机车轨道两端各安装一个无线电发射机，当机车在轨道上行驶时，装在机车上的无线电接收机对接收到的两个无线电波进行相位比较，根据相位差来进行精确定位的一种新方法，理论上证实了利用鉴相器进行无线精确定位的可行性，在具体的实现方法上有一定的创新性。

High Accuracy Wirless Positioning Method based on Phase Demodulating Technology

This paper interoduces a new method to distinguish the phase difference between two waves inputted to the phase detector via AD9901 phase detector, The method is to install radio transmitters on the both ends of the locomotive track respectively, when the locomotive is running in the track, the wireless receiver installed on the locomotive will receive two radiowaves and make a comparison between them to get a phase difference. The new method is to position precisely through the phase difference. In theory, feasibility of wireless auurate positioning is validated through the phase detector. And it is innovative in the practice.
