Paper Abstract

Calculation to the transmission of infrared radiation is a key step in the research of the ability of detecting targets for an infrared detector system. Water vapor and carbon dioxide is the main factor causing the infrared radiation attenuation in the atmosphere. According to the existing experimental data, the effect of H2O and CO2 to the transmission of infrared radiation on horizontal route in the standard meteorological conditions is analyzed, and the transmittance in the different bants is simulated by establishing a reasonable mathematical model and using the method of curve fitting. The high-accuracy algorithm and it’s accuracy is put forward, and is compared with the traditional formula of the infrared radiation transmission. Research results of calculation to the transmission of infrared radiation can obtain higher calculation accuracy, and it is of great significance in the research of the ability of detecting targets for an infrared detector system which needs high-accuracy.
