Abstract

Abstract

In order to improve detection ability of tracking system for the dim target, a set of automatic laser active illumination system is designed for actively illuminating the view field of tracking and measurement. The illumination diameter is always 10 meters at a distance of 0.2 km to 5 km away from the system. The amount of focusing group movement at -20℃ and 45℃ is given. The simulation results show that the illumination nonuniformity is less than 15%. By analyzing the optical aberration effects on the illumination uniformity and designed dimming group, the theoretical relationship between the dimming group movement and the illumination distance is gotten. The design result shows that the illumination in different distances will be uniform by adjusting the dimming group position automatically. The design and analysis results show that laser active illumination system can accomplish uniform illumination for the view field of tracking and measurement by moving the dimming group, which is beneficial for the dim target detection and measurement.
