Image Radiation Processing of 5 m Optical 02 Satellite Infrared Camera Based on Orbital Alignment Technology

Aiming at the radiation processing problem caused by the fact that the black body calibration data cannot track the corresponding observation strip in time due to the transmission of the same observation circle in different orbits of the 5-meter optical 02 satellite infrared camera, an image radiation processing technology based on the orbital alignment technology is proposed. After the actual image processing verification, the radiation processing technology of the 5-meter optical 02 star infrared camera is proved. It can not only satisfy the absolute calibration accuracy of the black body of the observation band in different down-pass circles, but also solve the relative radiometric correction accuracy of the single track statistics, and achieve good results in the actual ground processing process.
