摘要In order to realize spectral calibration for TanSat's hyperspectral Carbon Dioxide Spectrometer (CDS), a calibration system was established and relevant methodology such as design of the system, data acquisition and algorithms of data processing and etc was investigated. Based on the sounding principle, CDS's spectral requirements were presented. Design of calibration system and the adopted equipments was described. Then after the scheme of Orbiting Carbon Observatory's spectral calibration was compared, the modified methods such as automatic data acquisition, rotatable integrating sphere, power and dark calibration was analyzed. Finally, the methods of data processing were described as well. Experimental results indicate that the ILS concentration radios of CDS are more than 0.80, 0.81, 0.78 respectively and the intervals of FWHM are 0.0392-0.0424 nm, 0.123-0.128 nm, 0.157-0.168 nm respectively. The intervals of spectral sampling are 2.12-2.95, 1.97-2.27, 1.92-2.26 respectively. The comparison of on-orbit solar spectra indicate that the difference of central wavelength are less than 0.0013, 0.058, 0.065 nm respectively. It can satisfy the system requirements of CDS. 2017, Science Press. All right reserved.
