Passive source location attracts a growing interest due to its usefulness in various applications such as wireless communications, microphone arrays, sensor networks and so on. This paper combines the time differences of arrival (TDOA) and gain ratios of arrival (GROA) techniques to present a novel dual-station source location method of a known altitude(More)
