Description

Technical field [0001] The invention relates to the field of atmospheric parameter measuring instruments and atmospheric radiation transmission calculation software, in particular to a set of atmospheric radiation transmission correction system and correction method integrated by hardware equipment and calculation software. Background technique [0002] When using ground-based photoelectric observation equipment to track and detect aerial targets, the attenuation of the target's radiation signal must be considered. The molecules and aerosol particles in the atmosphere scatter and absorb the radiation signal from the target, which makes the measured value of the target radiation characteristic and the radiation value of the target before passing through the atmosphere have a big difference, and the difference varies with weather conditions and local atmospheric parameters ( Such as water vapor and other absorption gas content, atmospheric aerosol, temperature, pressure, etc.) have...
