摘要
讨论了大气消光作用对目标信号的衰减和大气后向散射对目标对比度的影响情况,从实用角度论述了大气消光的计算方法,得出常用几种波长激光的大气透过率情况,并分析了激光主动夜视系统中大气后向散射对图像对比度的影响。
The influence of atmospheric extinction on targets and atmospheric backscattering on the contrast are discussed. A pratical calculation of the attenuation coefficient is introduced also. And some atmospheric transmittances of different wavelength laser are drawing, the influence of the atmospheric backscattering on active night vision image quality is analyzed finally.
