| 摘 要： | 凝视型地球辐射探测仪是我国的新型空间应用遥感仪器,仪器具有全波探测通道和短波探测通道,采用腔体探测器,对地凝视观测,视场覆盖地表边缘,用于从空间的低轨道卫星平台测量地球辐射出射总量,提供地球辐射收支信息.作为定量化应用的遥感仪器,对仪器提出了高精度的定标需求,本文结合仪器的设计特点,提出了使用辐射标准传递方法,先用黑体标定凝视型地球辐射探测仪全波腔体探测通道,继而用全波通道标定积分球,再用标定好的积分球对凝视型地球辐射探测仪短波探测通道进行标定的办法,提高了短波探测通道的辐射标定精度.

| Abstract: | Earth radiation measurement(ERM) nonscanner,which includes a total-wave channel and a short-wave channel,is a new type of remote sensing instrument in our country.There is an activity cavity detector in each of these channels.ERM nonscanner is used to stare the earth and measures the earth radiation budget from the low orbit satellite and its field of view covers with the edge of the earth.Being a quantification remote sensor,ERM needs a high precision radiant calibration standard.The method of radiant cali... |
