Abstract
A method for characterizing an atmospheric propagation channel comprising: generating a database of atmospheric modulation transfer functions (MTFs) over a range of known values for at least one image-quality-related parameter; capturing at least one image of an object with an image capture device, wherein the image capture device is separated from the object by the atmospheric channel; deconvolving the captured image with every atmospheric MTF in the database to create a plurality of deconvolved, captured images; scoring each deconvolved, captured image according to an image quality metric (IQM); using an optimization-decision algorithm to find the best IQM score; and characterizing the atmospheric propagation channel as possessing the type and value of the image-quality-related parameters that are associated with the corresponding MTFs used to deconvolve the image having the best IQM score.
