Abstract

A new sensor fusion is proposed for radio-interferometric tracking applications. The proposed solution utilizes fixed infrastructure nodes equipped with simple radio transceivers, generating interferometric signals, which allows the tracking of moving objects equipped with similar radios. The proposed solution utilizes redundant low-frequency phase measurements of the interferometric signals, which reduces positioning error. The efficiency of the proposed fusion is illustrated by simulations and real measurement results.
