Abstract :
The different methods to process phase measurement data of a MFCW ranging system with their characteristics are well suited to be used for UHF RFID ranging. Our measurements show that ranging ISO 18000-6C UHF RFID tags under FCC regulations is possible in outdoor conditions despite the limited bandwidth. Our next steps will be to further compare the robustness of the algorithms and to conduct measurements in multipath environments. Additionally we will combine this approach with other localization techniques. Using multiple antennas or synthetic apertures, this approach can help to increase the radial resolution significantly.
