摘要
在红外制导系统中,大气衰减作用对红外探测有重要影响。为了深刻了解大气衰减影响,本文较为透彻地分析了大气各组分的衰减作用,并从理论上进行了探讨。造成大气衰减的主要因素是水蒸气(H_2O)、二氧化碳(CO_2)和气溶胶的吸收和散射作用,这也是大气中最为多变的部分。本文同时对其分布规律进行了分析。
In an infrared detection infrared guidance system, the atmosphere attenuation has an significant influence on To further understand this influence, the atmosphere attenuation function of each component in atmosphere is analyzed and discussed completely in theory. H2O, CO2 and aerosol are the main components which can result in attenuation. These components are also the changeful components in atmosphere. Meanwhile, their distribution rules are analyzed.
