Abstract
A control and processing system for use with an interrogator and an interrogation system employing the same. In one embodiment, the control and processing system includes a correlation subsystem having a correlator that correlates a reference code with a reply code from a radio frequency identification (RFID) tag and provides a correlation signal therefrom. The control and processing system also includes a decision subsystem that verifies a presence of the RFID tag as a function of the correlation signal.
Claims1
An interrogator comprising a control and processing system operable on a processor configured to:
- load a reference code including at least a plurality of bits of a reply code from a radio frequency identification (RFID) tag associated with an RFID object;
- produce an excitation signal for said RFID tag;
- receive at least a portion of said reply code from said RFID tag in response to said excitation signal;
- and compare said reference code to said at least said portion of said reply code from said RFID tag to verify a presence of said RFID tag.
