Various methods have been proposed for passive localization by using a network of sensors measuring different parameters such as the angle of arrival (AOA), time difference of arrival (TDOA), Doppler frequency difference of arrival (FDOA), differential received signal strength (DRSS), the gain ratio of arrival (GROA), or a combination of these pieces of information. In this paper, a method for target localization based on power of received signal in multiple stations has been proposed for two scenarios. In one scenario, the receiving antennas are omnidirectional and in the other scenario they are directional. We have derived a closed-form solution for source localization in the first scenario and we have proposed two methods (i.e., random search and Taylor series) for estimating the target location in the second scenario. Using computer simulations, the performance of our methods was compared with the Cramer-Rao …
