| Abstract: | HJ-1A satellite was launched successfully in September,2008.The hyperspectral imager(HSI) aboard HJ-1A is the first earth imaging interference spectrometer in China with multispectral bands and high spectral resolution advantages.According to the characteristics of spectral data,the preprocessing system composed of product production,quality testing and calibration processing units is designed.The system integrates the hyperspectral data processing method sets,effectively restrains the original data of noise,restores the spectral images,extracts multispectral information of 115 spectral bands,and provides the foundation for further processing and application of hyperspectral data. |
