摘要：Radio frequency identification (RFID) is poised for growth as businesses
and governments explore applications implementing RFID. The
RFID technology will continue to evolve to meet new demands for human
and target location and tracking. In particular, there are increasing needs
to locate and track multiple RFID-tagged items that are closely spaced.
As a result, localization and tracking techniques with higher accuracy
yet low implementation complexity are required. This paper examines
the applicability of direction-of-arrival (DOA) estimation methods to the
localization and tracking problems of passive RFID tags. Different scenarios
of stationary and moving targets are considered. It is shown through
performance analysis and simulation results that simple DOA estimation
methods can be used to provide satisfactory localization performance.
