猫眼光学窗口反侦测能力影响因素分析

为了提高我军光电对抗能力,达到攻防兼备的目的,必须在开展猫眼主动侦测研究的同时,开展猫眼光学窗口的反侦测策略研究。以探测激光回波功率为主要判断依据,利用数值仿真的方法对反侦测能力影响因素进行了定性和定量分析。结果表明,猫眼回波功率会随着探测器入射光功率、接收光学系统光学窗口面积、发射光学系统透过率、发射激光束发散角、猫眼物镜口径、焦距及反射元件失调量的改变而变化,且受漫反射背景和系统工作波长的影响。对影响因素的分析为反侦测策略的研究提供了理论依据。

Analysis of influence factors for anti-detection ability of cat-eye optical windows

To improve the ability of optoelectronic countermeasure and defensive and offensive capabilities,the methods of anti-detection should be studied as well as the cat-eye active detecting technology.Influence factors of anti-detection ability were qualitatively and quantitively analyzed by numerical simulation based on the reflected wave power.The simulation results show that reflected wave power is changed with the changing of incident power of detector,optical window area of receiver system,transmittance of emission system,divergent angle of incident laser,diameter and focal length of objective lens and maladjustment of reflector,and it is influenced by diffuse background and system operating wavelength.The research of influence factors provides theoretical basis for anti-detection strategy.
