Abstract

Abstract

In order to improve the spectral calibration precision of a High Resolution Imaging Spectrometer(HRIS) and to reduce the influence of the spectral shift on the surface reflectance retrieving of the ground spectra, especially in those wavelengths mostly affected by gaseous absorptions, the common data processing algorithms used in the on-orbit spectral calibration are introduced. The feasibility of these different algorithms is verified and their advantages and disadvantages are emulated with two cases of the laboratory spectral calibration under a thermal vacuum environment. It is shown that the algorithm based on spectra-matching, such as standard deviation method, correlation coefficient method and the minimized difference method can offer an advantage in the processing precision, and the extreme value method based on polynomial-fitting works much better in the processing speed. If polynomial-fitting method confirms the spectral shift fleetly in the pretreatment phase firstly, the spectral bound for spectral matching processing will be narrowed. A new algorithm with high processing precision and fast processing speed which combines spectra-matching and polynomial-fitting ideas was presented, it can offer the band-center wavelength accuracy better than 1 nm and can meet the need of the on-orbit spectral calibration precision of the HRIS.
