This paper presents the application of the SAR- based localization for UHF-RFID tags in smart warehouses, when readings are acquired along multiple apertures. The reader antenna motion is achieved through a robot typically employed for item inventory. Two different estimation methods are investigated. The first one foresees an average operation among consecutive estimated tag positions when the SAR-based method is applied to single trajectories. Indeed, the second one adopts the SAR-based method jointly to the phase data collected along multiple trajectories. The method applicability is discussed by considering different trajectory configurations and different sources of error through both numerical simulations and an experimental analysis.

Abstract

This paper presents the application of the SAR- based localization for UHF-RFID tags in smart warehouses, when readings are acquired along multiple apertures. The reader antenna motion is achieved through a robot typically employed for item inventory. Two different estimation methods are investigated. The first one foresees an average operation among consecutive estimated tag positions when the SAR-based method is applied to single trajectories. Indeed, the second one adopts the SAR-based method jointly to the phase data collected along multiple trajectories. The method applicability is discussed by considering different trajectory configurations and different sources of error through both numerical simulations and an experimental analysis.
