Imaging Spectrometer VIRS in Remote Sensing Experiments for the

摘要

SkyMed/Cosmo is a research project, supported by the Italian Space Agency, devoted to develop a satellite constellation for the monitoring of the Earth surface in the optical and microwave spectral ranges. The system is devised for such opera-tional purposes as disaster monitoring and observation of marine and terrestrial ecosystems over regional scale, and will be characterised by a very short re-visitation time. Nowadays the SkyMed/Cosmo project is expected to equip some satellites with different optical sensors comprising also a hyperspectral push-broom imager, having not less than roughly 40 spectral bands with a spectral resolution of 10 nm and radiometric resolution of 12 bit. This is a remarkable achievement that also requires a lot of theoretical and experimental work to be executed.
