摘要: 激光主动侦察的基本原理是基于光学系统存在的“猫眼”效应. 讨论了光学系统对入射激光的后向反射特性,推导了对于存在“猫眼”效应的镜头目标的激光测距方程,探讨了地面漫反射大目标和天空漫反射小目标背景下激光主动侦察作用距离的制约因素,并通过实验分析验证了这一结论的正确性.

Abstract: The principle of the active laser surveillance is based on the cat's eye effects of optical systems. The retrodirective reflection of the optical systems against the incident laser is introduced and the laser ranging equation of the targets which have such effects is derived in detail in this paper. The limis to the surveillance range are discussed in two types of backgrounds: the large size targets with diffuse reflection characteristics on the ground and the small size targets with diffuse reflection characteristics in the air. The conclusion is proved by the experimental analysis.

Key words: the active laser surveillance, laser, reflectivity, optoelectronic countermeasures
