英文摘要	With the advantage of acquiring spatial information and more spectral information, Hyperspectral imager is widely applied in the fields of earth-observation, precision agriculture, etc. In order to improve the quantitative ability of hyperspectral imagery, accurate radiometric and spectral calibrations are necessary. Shifts in channel center wavelengths and changes in spectral resolution may occur before and during flight. Base on calibration in laboratory, on-board calibration is necessary for acquiring the detector's actual center wavelengths and spectral resolution. In the paper, authors propose a new method for on-site spectral calibration of hyperspectral imager with man-made target. An experiment was carried out in Urad Front Banner, Inner Mongolia, China, on November 14th, 2010. The experiment result shows that this method can be applied in on-site spectral calibration to improve the quantitative studies on hyperspectral imagery.; Automation & Control Systems; Engineering, Electrical & Electronic; EI; CPCI-S(ISTP); 0
