SPACEFLIGHT HYPERION DATA RADIATION CALIBRATION PRELIMINARY STUDY

Radiometric calibration is the basis of both hyperspectral data applications and quantitative remote sensing. While at present, there is no good and suitable method for radiometric calibration in the aerospace hyperspectral data. The paper uses the highest spectral resolution Hyperion EO-1 satellite data in current world Spaceflight sensor as information source, using a variety of calibration models, which including of the calibration model based on atmospheric radiation theory, conversion model based on the characteristics of the image itself(Flat Field Model, IAR Reflectance Model, Log Residuals Modified Model, e.g.), linear model based on the experience of the ground calibration and so on, implementation Spaceflight hyperspectral data calibration study. Through the above model calibration contrast, and combined analysis with the field measured spectral curve, then we draw the conclusion that the calibration model based on atmospheric radiation theory is the best radiation calibration method for Spaceflight Hyperion data, so we provide the quality assurance for the effective application of Spaceflight Hyperion data.
