Paper Abstract

The problem that the infrared radiation transmits in the atmosphere is always paid attention by the designers who deal with the photoelectricity measurement system and the researchers who deal with the radiation transmission in the earth atmosphere. There is more and more attached importance to the research of the atmospheric transmission model. There are many studies relating to the atmospheric transmission characteristic of infrared radiation, such as the object infrared detection, the navigation, the communication, the earth resource remote survey, etc. The radiation transmittance will be weakened because of the absorption and the scattering. The atmospheric transmittance is an important parameter to measure the attenuation. This paper summarizes the infrared radiation's transmission process in atmosphere, introduces the keystone of atmospheric transmission computation, analyzes the absorption attenuation of the atmospheric gas such as steam and carbon dioxide, the scattering attenuation and the attenuation caused by meteorological condition, and gives the atmospheric transmittance simplified algorithm combining the fact of project. Finally this paper gives the atmospheric transmittance computation result under given meteorological condition, also gives the contrast with LOWTRAN7.0. The algorithm reduces the troublesome step brought by using atmospheric transmission software, it can basically satisfy the request from engineering calculation without high accuracy although the precision is relatively bad.
