Algebraic distributed source localisation algorithm using TDOA and AOA measurements

The Journal of Engineering, 2019
This study proposes an algebraic distributed source localisation algorithm that combines time difference of arrival (TDOA) and angle of arrival (AOA) measurements. The proposed algorithm uses AOAs to remove the unknown parameters in TDOA equations caused

Time-Difference-of-Arrival (TDOA)-Based Distributed Target Localization by A Robotic Network

IEEE Transactions on Control of Network Systems, 2020
Localization and tracking of a moving target arises in many different contexts and is of particular interest in the field of robotic networks. One important class of localization schemes exploits the time-difference-of-arrival (TDOA) of a signal emitted by the target and detected by multiple sensors.
