Radio frequency ID Doppler motion detector |
摘要 |
A system and method for a radio frequency identification (RFID) reader for use in an RFID detection system. The reader has an RF source for generating RF signals. An antenna is coupled to the RF source. The antenna transmits interrogation RF signals to one or more RFID markers within an interrogation zone and receives communication signals from one or more items within the interrogation zone. The communication signals include Doppler signals indicating movement of an item within the interrogation zone. A receiver receives the communication signals and motion detection circuitry detects the Doppler signals.
