This paper presents a prototype direction of arrival system designed to locate passive RFID (Radio Frequency Identification) tags in a commercial warehouse environment. The system design is discussed with focus on a MUSIC based algorithm designed to cater for multiple reflections. Special emphasis is placed on the results of a trial of the system in a warehouse.
