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. S_m = 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.
