摘　　要：白天恒星探测工作涉及到很多环境因素的影响,现有文章对理想环境及云层存在时,不同参数条件下的测星工作进行了分析,除去主要影响因素云层外,红外辐射在大气的传输过程中,还有不确定因素雨、雾的影响。主要针对这两种不确定因素展开研究,雨和雾的存在在时间、地域以及高度因素上都是不确定的,结合已有的经验公式,针对不同参数情况下的辐射衰减情况进行分析,定量明确雨和雾对辐射传输的影响。Star target detection is influenced by many environmental factors during daytime. Star target detec tion at the condition of different parameters is analyzed in an ideal environment and the presence of clouds. Infrared radiation is also influenced by uncertain factors such as rain and fog except the main influence factor such as clouds during the transmission in atmosphere. These two uncertain factors are researched. The presence time of rain and fog, place and height are all uncertain factors. Incorporating with the existing experience formulas, radiation attenua tion states at the condition of different parameters are analyzed. The influence from rain and fog on radiation trans mission is quantified.
