Abstract:

Due to the need of post-launch calibration of hyperspectral imagers, three cross-calibration technical solutions are proposed. Matching technologies including field, time, geometry and spectrum in the process of cross-calibration are analysed. Algorithms and models in matching technologies are validated by the use of the data of HJ-1A/HSI, EO-1/Hyperion. By the application of three technical solutions with site-calibration method, the frequency of post-launch calibration can be improved and site-calibration coefficients will be validated quickly. The level of quantitative application of hyperspectral data can be promoted effectively.

Key words: hyperspectral, cross-calibration, matching, quantification
