Paper Abstract

Infrared radiomentric calibration is of critical importance for information quantification of remote sensing of environment at infrared spectrum. In the quantitative analysis, the calibration of the measured spectra is very important. LWIR Interferometric Hyperspectral Imager Spectrometer Prototype (CHIPED-1) is developed for studying Radiation Calibration. Two-point linear calibration method is carried out for the spectrometer by using blackbody respectively. Firstly, relative intensity is converted to the absolute radiation lightness of the object. Then, radiation intensity of the object is converted the brightness temperature spectrum by the method of brightness temperature. The result indicated that this method of Radiation Calibration calibration was very good. This calibration method is of significance to the further analysis of atmospheric transmission and the retrieval of the concentration of infrared chemical gas in atmosphere.
