Why is the definition of Radiometric resolution in Synthetic Aperture Radar (SAR) different from its simple definition in optical sensors (although both products are images in a numerical format or digitized):
<ul>In optical sensors: Radiometric resolution refers to the smallest change in intensity level that can be detected by the sensing system (8 bits, 16 bits...).
Whereas in SAR, it's the measurement uncertainty of the radar backscttering coefficient (
