Abstract	To recognize the position of moving objects, facilities or important equipments has been regarded as a hot issue in the future environment which needs ubiquitous characteristics. Furthermore, it is indispensably needed to acquire location data in order to realize an infrastructure of sensor network system. Namely, to get distance data is the preliminary information to complete localization of a moving object in local area. Even though there have been several researches on it, there are however still much amount of problem to get precisely exact distance data. Out of them, the research on using TOF (Time-of-flight) is very few as well as could be thought of as a cutting-edge technique. Moreover, it is very difficult to get minutely RF signal's TOF for getting short distance data; that is, very complicated signal processing skills are requested for realizing it. In this paper, we present a new methodology of RF short ranging technique based on the vernier effect due to the use of heterogeneous operating clocks.
