摘要
Abstract
The infrared guided weapon is mainly based on the characteristics of the radiation and contrast about target and background to detect, recognize and track the target. The aerosol and visibility have great influence on infrared radiation in the atmosphere. The article analyzed the effect of aerosol and visibility on the mid and far infrared light-wave transmission in the standard atmosphere and mainly focused on the effect of aerosols within the same visibility and the same aerosol about different kinds of visibility on the mid and far-infrared (3-5mm, 8-12mm) light-wave transmission. The results show that the target-background contrast is mainly influenced by atmosphere transmittance. The types of aerosol and visibility contribute a lot to transmittance and target-background contrast under the standard atmosphere. And both of transmittance and contrast in the band of 8-12mm are always better than those in the band of 3-5mm. Also, transmittance and contrast have great difference in different aerosols within the same visibility. In the both 4 typical aerosols within the same visibility and the aerosol of rural about 5 kinds of visibility, the 3.4-4.2mm and 9.5-12mm bands are highly recommended in the target detection for their higher average value of transmittance and contrast.关键词
