I am just curious about the resolution definition in satellite image.
what you said about the resolution in optics and image processing makes sense to me. Usually, diffraction determined the resolutin limit of a linear system. 土丘 could be understood as the Fourier transform of the aperture used in the imaging process.
The effect of both aberration and motion blur could be treated as a point spread function, and deconvolution could help to remove these kind of effects to certain extent. However, it couldn't improve the resolution limited by the aperture and wavelength.
