Chipless tags infrastructure based localization in indoor environments

Abstract

In this work, we study dielectric resonator (DR) tag based localization using time difference of arrival (TDOA) method in indoor environments. DRs, which act as chipless tags, are used as reference nodes in order to localize an object equipped with a reader. The ringing behavior of the DR tags is utilized as the fingerprint of the tags, which is used to estimate TDOA using the cross-correlation algorithm. Simulations and measurements are performed to examine the performance of the proposed DR tags and the localization algorithm.
