Description

To change or not to change the SNR requirement (SNR > 20 dB on each pixel), that is the question. Basically, to make optics design easier by increasing focal length and hence increasing the f/# of the system, we can ensure better GSD and spatial resolution, at the cost of SNR. Both spatial resolution and SNR are metrics of image quality, and they need to be balanced with each other. By decreasing the SNR requirement, this is an attempt at achieving this balance.

Assigned to: @Nabiha Saghar
Deliverable: A short document with references that provides justification for lowering the SNR requirement.
