Abstract
Aspects of the present disclosure include methods, systems, and non-transitory computer readable media for transmitting at least one incident radar signal, receiving at least one reflected radar signal in response to the at least one incident radar signal reflected from a person associated with the RFID tag, determining a first movement vector of the person based on the reflected radar signal, transmitting at least one incident RFID signal, receiving at least one backscattered RFID signal from the RFID tag, determining a second movement vector of the RFID tag based on at least one phase measurement of the at least one backscattered RFID signal, and determining whether the RFID tag is associated with the person based on the first movement vector and the second movement vector.
