研究了光电成像系统中广泛存在着的“猫眼”效应, 针对“猫眼”目标的回反射特性, 建立了不同情况下回波强度的数学模型, 并据此模型, 借助TracePro软件对典型目标在不同激光发射距离、不同镜头离焦量、不同入射角度下的“猫眼”效应进行仿真计算分析。结果表明, 理论计算和仿真结果一致, 因此可以用于指导未来激光主动探测系统设计。

Cat-eye effect widely existing in electro-optical imaging system is researched. According to the retro-reflection property of a cat-eye target, a mathematical model under different echo wave intensity is established. Based on the model and TracePro software, the cat-eye effect of a typical target with different laser emission distance, lens focal shift and incident angel is simulated and analyzed. Results show that theoretical calculation accord with the simulation results, so it can be used to guide laser active detection system design in the future.
