Superresolution in dewarped anisoplanatic images

摘要

I present a simple theoretical model for dewarped imaging through a turbulent medium and calculate the degree of superresolution that can be attained by dewarping the distorted instantaneous images registered through a turbulent atmosphere. The estimates show that on 1 km near the ground propagation path, spatial frequencies of the dewarped image can exceed the diffraction limit three times with a probability up to 10percent.
