Passive Source Localization Using Joint TDOA, GROA, and AOA Measurments

Passive source localization is the aim of many applications in the commercial and military fields. In this paper, we propose a new localization approach that using joint time difference of arrival (TDOA), gain ratio of arrival (GROA), and angle of arrival (AOA) of the received signal in the number of the sensors. It will be shown that the performance of localization, using joint measurements is out-performed compared with each of them separately by presented Cramer Rao Lower Band (CRLB). It is shown that the estimator performance is equal to this presented CRLB.
