摘要
大气背景辐射对于空间预警系统的研究具有极其重要的作用,基于辐射传输的理论,建立吸收波段大气环境背景仿真系统,针对特定区域,对白天和晚上的情况作了仿真模拟,分析了云顶温度等大气参数对辐射背景的影响,并将4.3μm通道(白天)的仿真结果与AIRS的结果作了比较,两者的均值差异为13.2%。
Atmospheric background radiation is very important to the research of space early warning system.Based on the radiation theory,we established a system to simulate atmospheric background radiation.With the system we simulated the background radiation in specific area at different time(daytime and night),then the effects of atmospheric parameters including cloud-top-temperature was analyzed。We compared the result of 4.3 μm band with that of AIRS,and got the conclusion that the difference of mean values is about 13.2%.
