英文摘要	To invert precisely the CO2concentration in atmosphere by the green-house gas information obtained by satellite remote sensing, this paper researches the high spectral detection technology with high spectral resolution and high Signal-to-Noise Ratio (SNR). A method of fine spectrum splitting was demonstrated using a large area diffractive grating at three spectral bands of 0.76, 1.61, 2.06 m. According to the theory of remote sensing detection, the theoretical SNRs of the three bands were deduced to reveal the restrict relation between the spectral resolution and the SNR. The detectors with large pixel sizes and high quantum efficiency were selected to detect the weak signal with high SNR by using methods of pixel combination and blind pixel correction. A spectral calibration facility was established to measure the instrument line shapes (ILSs) of the three bands, and the center wavelength and the full-width at half maximum (FWHM) of each spectral channel were determined with a Gaussian fit to the core of each ILS. The results of the spectral calibration indicate that the spectral resolution is 0.04 nm. The above-mentioned study provides the basis for the realization of accurate detection of absorption spectra and 1-410-6reversion precision of CO2. 2015, Chinese Academy of Sciences.
