[en] On the basis of characteristics of imaging spectrum data, and adopting pre-processing technology of high precision spectral data and correlation coefficient spectral matching methods, the authors succeeded in analyzing spectral signature of rocks and minerals, and in extracting the diagnostic spectral information. Using the models and methods presented, the authors have carried out the experimental research in uranium ore-districts in Tengchong area, Yunnan province, and Hailar basin, Inner Mongolian Autonomous Region, and good processing results have been achieved
