Abstract :
Hyperspectral Imager Suite (HISUI) is a next-generation Japanese optical sensor that is composed of a hyperspectral imager and a multispectral imager. Combination of hyperspectral and multispectral imagers contributes land remote sensing with high spectral and spatial resolution. Validation of the HISUI evaluation model, including environmental test such as vibration test and thermal-vacuum test has been carried out to meet the science requirements on the sensor under the space-borne conditions. Major performances of the sensors are obtained. Spectral response of each band of the hyperspectral sensor, distortions in a spectrometer in terms of smile and keystone properties, are investigated. The test results of the evaluation model show appropriate performance of the sensors.
