Considering the thermal infrared system and end users need, a statistical non-uniformity correction method is proposed to shorten the time to find suitable and broad ground calibration area. Its basic assumption accords to classically linear model, but it extends traditional operating manner. Specifically and first, for each circle the onboard non-uniform parameter is strictly calculated via sensing...
The relative radiometric calibration is essential to get high-quality remote sensing images. An efficient way to bypass the quest of uniformity is to use the satellite agility in order to align the ground projection of the scanline on the ground velocity. This weird viewing principle(side-slither) allows all the detectors to view the same landscape. A relative radiometric calibration model based on...
