Abstract: 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.
