Abstract

In this paper, we propose a method and condition of locating the position of an object in one dimension by using the phase difference of arrival(PDOA), To get a phase difference, the comparator of a wayside radio station(WRS) compares the reference signal with the received signal, Therefore, we can locate the position of a moving object. Finally, by using the simulation of a computer we analyze their values.
