| 摘 要： | 介绍一种方法在低或零中频（IF）的半双工通信环路的距离测量。测距系统测量本地振荡器不同步的两个收发器的之间的距离。通信环路通过解调,重新调节和重新传输已接收的信号提供一个具有相同的载波和调制频率的重传信号作为接收信号。

| Abstract: | A method and system for distance measurement in a low or zero intermediate frequency（IF）half-duplex communications loop measures the distance between two transceivers without synchronizing the local oscillators of the two transceivers.The communications loop demodulates,re-modulates and retransmits a received signal to provide a re-transmitted signal that has the same carrier and modulation frequency as the received signal. |

| Keywords: | distance measurement phase-hold carrier frequency |
