| Abstract: | Infrared radiometric calibration is of critical importance for information quantification of satellite remote sensing of environment at infrared spectrum. In this paper we propose plans for laboratory calibration at middle infrared and far infrared spectrum for Chinese space sensors. We review and compare various advanced calibration techniques, and suggest calibration methods based on widely tuneable lasers, HgCdTe/sphere detectors, InSb/sphere detectors and thin -film thermopiles TS -76. Technical proposals are briefly discussed. |

| Keywords: | cryogenic absolute radiometer infrared radiometric calibration uncertainty |
