摘　　要：为了研究大气气溶胶对激光斜程传输的散射特性,建立了基于米氏散射理论的1.064μm激光大气斜程散射模型。利用MATLAB软件对模型进行仿真计算,分析了斜程散射光辐射参量的分布特性。并结合地面探测分析了探测器的方位及探测方向对散射光辐射照度的影响。结果表明,该模型为机载激光指示器系统的战术训练、地面激光探测提供了可靠的理论依据。To study the slant path scattering characteristics of aerosols in atmosphere,the slant path scattering model of 1.064μm laser was built based on Mie scattering theory.The distribution characteristics of radiative parameters were analyzed with the help of MATLAB.Combined with ground surface detection,the effect of detection azimuth and angle of a detector on the scattering intensity was discussed.As a result,the model is a credible method for the tactical training of airborne designator system and ground laser detection.
