摘要
红外长波波段海空背景大气透过率的仿真计算在原有理论计算的基础上，修正了海背景中大气饱和水汽压的计算，推出了沉积水量的表达式，考虑了不同高度分子吸收问题，分别拟合出了在海平面水平路程上由波长和沉积水层厚度决定的水汽光谱透过率函数以及由波长和路程长决定的二氧化碳光谱透过率函数，分析了臭氧的影响，给出了大气透过率的表达式。
Abstract
Based on original theoretical calculation, the expression of deposit vapor volume in atmosphere under sea background is deduced, and calculation of saturated water vapor pressure in atmosphere is modified. Atmospheric molecule absorption in different height is considered. Spectral transmittance functions of vapor and carbon dioxide are presented respectively. In addition, the influence of ozone is analyzed. Expression of atmospheric transmittance is shown.
