DOI: 10.1109/tnet.2022.3162930
Abstract: This paper studies the localization problem using noisy range-difference measurements, or equivalently time difference of arrival (TDOA) measurements. There is a reference sensor, and for each other sensor, the TDOA measurement is obtained with respect… read more here.
