Abstract

Statistical variations in the size, position, shape and orientation of hexagonal ice crystals in a 3D volume complicates the modeling of image transfer through cirrus clouds. These variations will give rise to fluctuations in image quality as measured by the MTF of a single realization of a cloud/receiver combination. Computing the average MTF from several realizations of the cloud/receiver combination, allowing for a different cloud composition on every realization can alleviate these fluctuations. In this paper, we present the result of the multiple MTF for clouds of different optical depths, distinguishing the separate contributions of scattered as well as unscattered light. Finally, we apply the MTF thus generated to create images of objects as seen through the cloud.
