摘要: 为了给在轨卫星红外地球敏感器性能评估提供更多参考依据,通过对某颗长期在轨正常运行卫星所配置的红外地球敏感器辐射强度数据进行统计分析,给出辐射强度短期、中期和长期的变化规律,并分析造成这种变化的内在机理.分析结果表明,辐射强度短期与星下点纬度相关且呈周期变化;中期与季节相关且呈周期变化;长期主要与红外地球敏感器自身特性相关呈逐渐衰减趋势.该结果可以作为在轨红外辐射强度判读的依据.

Abstract: By analyzing the orbit data of a long-term running satellite, the evolution laws of infrared earth sensor radiant intensity (IESRI) are concluded for evaluating the performance of infrared earth sensor. The short-term changing of the IESRI depends on the latitude of satellite orbit. The medium-term changing depends on the period of the season of earth. The long-term changing depends on the capability of infrared earth sensor which is attenuated with the running time. The results could be the rules for analyzing the orbit data of IESRI.

Key words: infrared earth sensor, radiant intensity, orbit data, evolution law
