2、衛(wèi)星紅外探測通道外場輻射定標的場地.我國靜止氣象衛(wèi)星風云二號(FY-2)系列是自旋穩(wěn)定衛(wèi)星,其紅外通道無法進行在軌時的星上絕對定標,而青海湖對于位于東經(jīng)105。赤道上空的FY-2衛(wèi)星來說,衛(wèi)星天頂角有36。,超過了外場輻射校正測量規(guī)范要求.本文介紹了利用我國南海海面水體輻射,進行與靜止氣象衛(wèi)星的同步測量試驗,開展衛(wèi)星紅外通道在軌外場輻射定標處理的可行性研究.在分別對FY-2B與FY-2C的測量數(shù)據(jù)處理后,初步確定我國南海海面可以作為我國靜止氣象衛(wèi)星在軌輻射定標的場地.關(guān)鍵詞:自旋穩(wěn)定;靜止氣象衛(wèi)星;輻射定標;紅外通道;中國遙感衛(wèi)星輻射校正場中圖分類號:P414
