Abstract:

The problem of transfer of radiation from an isotropic glowing element of a surface in a spherical atmosphere by the Monte-Carlo method in order to determine the scattering function of a point source which is equivalent to the optical transfer function (OFT) of the atmosphere. Winter and summer models of the atmosphere5 as well as the variant of the Elterman’s model with visibility range. Sm = 15 km were employed in the calculation.
It is shown based on the data obtained that when an object of the order of 600 m in size is observed at the nadir taking the optical transfer function into account can give corrections exceeding 25%. When small (20–100 m in size) objects are observed the atmosphere has the effect of changing the contrast of the object without destroying its spatial structure.
