Using Chirp Signal for Accurate RFID Positioning

摘要：

This paper presents performance evaluation of a positioning system using pulsed chirp signal as the cooperative signal over a relatively small area. The aim is to investigate potential advantages of chirp pulse in localizing active RFID with high positioning accuracy in an approximate indoor environment. Positioning performance of chirp signal is compared with that of normal pulsed sine wave signal using Time of Arrival (TOA) location method. The numerical results show that chirp pulse outperforms sine wave signal in terms of much higher positioning accuracy in small coverage area.
