In order to provide calibration image selection strategy for non-synchronous alternative spectral calibration, the oxygen absorption band near 760 nm was studied, spectral data of five underlying surface types of vegetation, withered vegetation, manmade objects, sand and snow were chosen to analysize. Based on simulated data, the analysis of calibration results and the accuracy was carried out, and spectral calibration errors of different underlying surface types was compared. Results showed that calibration errors based on the spectral angle matching method and the euclidean distance method are almost the same. When standard deviations of surface reflectance are less than 0.05 nm in 730 nm-800 nm, the spectral calibration precision is within ±0.5 nm. The olive green gloss paint and lush vegetation are not suitable to non-synchronous alternative spectral calibration.
