摘　　要：利用光学窗口"猫眼效应"进行的激光主动侦察易受光学镜头的像差的影响。通过建立球差光学系统"猫眼效应"的理论模型,并运用数值仿真计算的方法,分析了目标光学系统的球差与侦察激光的回波发散角、接收功率以及最大侦察距离等参数的关系。结果表明目标光学系统的球差会明显增大回波发散角、降低回波接收功率和减小最大侦察距离,对激光主动侦察造成不良的影响。The active reconnaissance which is based on optical system＇s ＂cat-eye＂ effect is easy influenced by optical system＇s aberration. A model of spherical aberration optical system＇s ＂cat-eye＂ effect was established and the numerical simulation calculation method was used to analyse the relationships of target optical system＇s spherical aberration with the reconnaissance laser＇s echo divergence angle, the received echo power and the maximum reconnaissance distance. The results indicates that target optical system＇s spherical aberration could observably increase the echo divergence angle,decrease the received echo power and the maximum reconnaissance distance. It brings bad influence to the active laser reconnaissance.
