Measurements and Applications
Pushbroom-type dual-prism Imaging Spectrometer with high radiometric accuracy and medium Signal-to-noise Ratio, operating from UV (320 nm) to SWIR (2400 nm) , based on a single MCT Detector/focal plane. The HIS aims at accurate spectral imaging on land and ocean for climatological background radiometric data acquistion and supporting cross-calibration with other stellites/sensors and on PICS/instrumented sites with highest resolution (50 m)
