Abstract

The IR seeker is a device that detects heats radiated from a target and provides the target position with servo system of the missile. Among various kinds of seekers, the rosette- scanning seeker ins a tracker in which a single IR detector scans the total field of view (TFOV) in a rosette pattern, and then produces 2D image about a target. Since the detected image has various shapes according to the target position in the TFOV, it is necessary that we investigate the tracking algorithm applicable to the different shapes. In this paper, we present a comparative study of the projective and the moment technique among the various target tracking techniques. Using the 3 degree-of-freedom simulator, we evaluate two algorithms and confirm the better performance of the moment technique as a tracking one.
