Abstract
—A novel RFID synthetic aperture radar (SAR) based
localization method using an antenna trajectory estimated using
known reference tags of known location is proposed and
demonstrated to find the location of target tags who’s location is
not known. A robot with an integrated RFID reader and antenna
is used to obtain phase measurements of both the reference and
target tags in an indoor environment. The trajectory of the moving
RFID antenna is estimated using an Inverse SAR (ISAR) sensing
algorithm. The trajectory is then combined with the phase
measurements of the target tags to compute their location using a
conventional SAR algorithm. The performance is compared to
target tags located by SAR where the antenna trajectory is
measured by LiDAR. Experimental results show similar
performance (15cm mean absolute error) using both LiDAR-SAR
and ISAR-SAR algorithms. Compared to previous SAR based
systems, the ISAR-SAR based RFID system is a cost-effective
solution which is more commercially attractive for inventory
tracking applications.
