Abstract Only the angle information of the targets can be obtained by infrared single-station. It is hard to get the distance information, which makes it impossible to track 3D objects in rectangular coordinates. A new algorithm is proposed for estimating the tracking parameters of bearings-only measurements, which avoids the complexity of traditional multi-station cross-location algorithms. According to the characteristics of high measurement rate by infrared sensors, azimuth sequences, obtained by an infrared single-station sensor, are utilized to measure the track parameters. Target tracking problems for single station could be solved effectively in such bearing-only mode. Simulation results show that the proposed algorithm has good filtering performance in tracking maneuvering targets, as well as the targets with straight-line motion.
