Paper Abstract

PRISM (processes research by an imaging space mission) is a spaceborne hyperspectral imager studied by ESA for a future satellite devoted to land surface research. The prime objective of the mission would be the observation of biophysical processes from space at the local to regional scale. PRISM is designed to be flown on a medium-size satellite in a polar sun-synchronous orbit, providing coregistered spectral images in two spectral regions: the visible and short-wave infrared range (450 - 2350 nm), where it works as an imaging spectrometer with a spectral resolution of about 10 nm, and the thermal infrared range from 3.5 micrometer to 12.3 micrometer, divided in 4 spectral bands with a typical width of about 1 micrometer. The spatial resolution on ground is about 50 m and the swath about 50 km. Across-track pointing capability is available for convenient accessibility of the whole Earth. The objectives and requirements are described in this paper with a particular emphasis on the derivation of the radiometric requirements. The status of the instrument studies and of the related technology developments are also summarized.
