Abstract (en)
[origin: WO2010091746A1] The invention relates to a method and a system for determining the distance, speed, and/or direction of movement of an RFID transponder. The transponder is interrogated by an RFID reading device as commonly known, so the reading device transmits a power supply carrier signal that is modulated during some phases. A radar module simultaneously transmits a radar signal which is received and reflected by the transponder. The reflected radar signal is finally received again by the radar module. The position of the RFID transponder can be determined from the reflected, received radar signal. The radar signal is transmitted especially when no interrogation data is modulated onto the power supply carrier signal. Furthermore, the power supply carrier signal and the radar signal have different frequencies.
