In order to calibrate the infrared channel of space borne remote sensor and verify the authenticity of data products. In August 2018, we used the portable Fourier transform infrared spectrometer (D&P 102F) and an infrared standard plate to measure the surface emissivity spectra of the field at Dun Huang Radiometric Calibration Site for many times under different observation conditions. Based on the iteration spectrally smooth temperature and emissivity separation algorithm, the spectral emissivity and temperature of Dun Huang Radiometric Calibration Site were separated by setting the temperature difference interval with different precisions and performing multiple iteration smoothing analysis on the measured spectral data, and compared with the emissivity of CE312 channel obtained by multi-channel temperature and emissivity separation algorithm.
