We present an algorithm for direction of arrival tracking that allows operation below the ambiguity threshold of the direction finding system. Using multiple target tracking techniques, the algorithm turns the most likely directions of arrival of each measurement into multiple potential tracks and then selects the true track as that with the maximum cumulative likelihood. The improvement offered by the algorithm, namely the extension of the ambiguity-free domain, is demonstrated by simulated experiments
