Abstract

The earth background radiation is an important factor in the detection of space to earth, since it is necessary to study the influence of different surface on infrared detection. In this research, the daytime atmospheric meteorological data of 2021 summer solstice in typical areas of China are measured by multichannel infrared radiometer SABER(Sounding of the Atmosphere using Broadband Emission Radiometry). Calculated the infrared background radiation with a wavelength of 1-6 μm, at a same time, compared the results of the measured data in the South China Sea with the results of the Standard data. The calculation results show that the difference in the earth background radiation calculated by the standard in different regions is not obvious. The atmospheric data can more accurately reflect the earth background radiation of different surface types. At the time, in different regions the earth background radiation is mainly concentrated in the 1-2.5 μm band, the infrared background radiation in desert and forest region is stronger than that in snow mountain region, and the radiation intensity in ocean region is weakest.
