Radiometric calibration plan for the Hyperspectral Imager Suite (HISUI) instruments

摘要

The Hyperspectral Imager Suite (HISUI) is the Japanese next-generation Earth observation project, which will be onboard ALOS-3 platform. HISUI sensor will be composed of hyperspectral imager (185 spectral bands in VNIR-SWIR region with 30 m spatial resolution) and multispectral imager (4 spectral bands in VNIR region with 5 [m] spatial resolution), and is being developed by Japanese Ministry of Economy, Trade, and Industry (METI) as its third spaceborne optical imager mission after JERS OPS and Terra ASTER. HISUI will provide the earth observation data for global energy and resource issues as well as for other applications such as environmental monitoring and forestry. This paper shows the radiometric calibration plan for HISUI long-term observation.
