摘要

The spinning reticle seeker is the significant part of the infrared (IR) detecting system. The track of the light spot is no longer a circle because its movement is disturbed by the spinning of the missile. In this paper, we analyze the effect of the missile's spinning on target position calculation, and obtain three important conclusions for the detecting system to improve its competence. Firstly, the calculated target position swings around the actual value. Secondly, the maximum error rate decreases along with the polar radius of the target position. Thirdly, the period of the swinging value is the lowest common multiple of the scanning and the spinning frequencies. These conclusions are well proved by the simulation results.
