Modeling on 3D Atmospheric Transmission of Infrared Radiation
On the basis of analysis atmosphere, a new method of calculating the atmosphere transmissibility is introduced. The 3D model of atmospheric transmission of infrared radiation is established for calculating atmospheric transmittance, thermal emission, and single scatter solar radiance along sensor-to-target lines-of-sight (LOS) within a three-dimensionally varying atmosphere. This model analysis the various factors which affect the infrared radiation of atmospheric transmission. The calculation results of atmosphere transmissibility not only consider the atmosphere layering situation along the vertical direction but also atmosphere molecules distribution variable along the horizontal direction. Finally, the simulation images show in this paper.
