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 air targets, the attenuation effect of the atmosphere on target radiation signals must be considered. Molecules and aerosol particles in the atmosphere scatter and absorb the radiation signal from the target, so that there is a large difference between the measured value of the radiation characteristic of the target and the radiation value of the target before passing through the atmosphere, and the difference varies with weather conditions and local atmospheric parameters ( Such as water vapor and other absorbing gas content, atmospheric aerosol,...
