Abstract
An RFID tag reading system and method estimate true bearings of RFID tags associated with items in a controlled area. A plurality of secondary receive beams are rotated in a cycle about a boresight axis of a primary receive beam to generate a plurality of secondary receive signals. A controller processes all the secondary receive signals received in the cycle to estimate a true bearing for each tag in the controlled area.
