Abstract

In order to meet the needs of on-orbit radiometric calibration of remote sensors, an infrared channel field radiometer (ICFR) was developed for on-site measurement. The working principle, optical system design and mechanical structure design of ICFR were expounded, the ICFR laboratory radiometric calibration and calibration uncertainty analysis were carried out. The results show that the received radiance of each ICFR channel has a high linear relationship with the response DN value, and the radiometric calibration uncertainty is better than 0.18 K. The ICFR thermal shock resistance and working environment temperature adaptability tests were carried out. The results show that ICFR has strong thermal shock resistance and can be applied to the working environment of -20℃~50℃, It has an important application prospect in the field calibration of remote sensor thermal infrared band.
