Abstract

This paper presents an approach to modeling effects of atmospheric turbulence in digital images, which allows variation in the atmospheric coherence diameter over the field-of-view. Characteristics of the imaging system are used in deriving a digital filter to represent turbulence, and in evaluating its accuracy. The form of the filter is appropriate for an image/array processor which performs direct convolutions rapidly.
