Location and tracking of items moving on a conveyor belt and equipped with UHF-RFID tags

In this paper, the numerical investigations of the performance of a new synthetic array phase-based technique for localization and tracking of items equipped with UHF-RFID tags are presented. The technique takes advantage of the fact that the tagged items move along a conveyor belt, whose instantaneous speed and path are known a priori. Effects on the location accuracy of thermal noise, environment clutter and multipath, have been considered by numerical simulations in a realistic scenario.
