Spaceborne Hyperspectral observation (i.e. hyperspectral remote sensing in uv-visible-infrared spectral range) of Earth and for Planetary science, plays a very important role in improving scientific understanding, environmental and resource monitoring.
Signal to Noise ratio (SNR) is a very important parameter (or quality metric) of any Hyperspectral instrument indicating its potential to meets its desired observational goals.
Due to demanding need on higher spectral and spatial resolutions, it become challenging to good / high SNR to meet the desired observational goals.
In view of this I wish to discuss or seek suggestions of various options or ideas by which SNR of Hyperspectral instrument can be improved. Ideas or options may be either for instrument design aspects or for image or data processing aspects.
