Abstract:

Cryogenic radiometer has been used in remote sensor radiometric calibration fields as radiation primary standard with a uncertainty less than 10-4. The calibration process of cryogenic radiometer transfering to spaceborne remote sensors is summarized, and the uncertainty of all levels of the transfer standard is introduced in detail. Through actual calibration apply of VXR, TXR in NASA’s EOS plan and radiance detector in FY-2, broad application  prospect of this calibration technique  is shown.

Key words: cryogenic radiometer, radiometric calibration, remote sensor calibration, radiance detector, trap detector
