Paper Abstract

In the case of design of atmospheric optical remote sensing systems functioning with dense clouds it is necessary to take into account both multiple scattering and absorption of electromagnetic waves on water aerosol. These factors have an especially strong effect on the propagation of infra-red light beam on large distances. In the report a thick layer of chaotically distributed absorbing particles with narrow indicatrix of scattering is considered. A theory of radiation transfer is developed for the case of oblique lighting of the medium boundary. As a result it is managed to analyse some peculiarities of evolution of angular and spatial structures of the wave beam. The behaviour of the last one is anomalous in comparison with a case of normal illumination of the boundaries. Then occurred a very quick: increasing of widths of angular and spatial distributions of light intensity in some interval of distances. So they depend on the height nonmonotonicaly. Also maximums of the angular and spatial distributions anormalously quick shift themselves towards the boundaries normal direction. The investigations are made both analytically and numerically.
