Abstract :
This paper investigates the theoretical requirements for unique localization of multiple emitters using time delay of arrival (TDoA) subjected to the data-association problem. Specifically, an examination is carried out to find the necessary fundamental requirements to solve the so-called ghost node problem pertaining to sensor arrays.
