SIMULATION OF CENTIMETER WAVE PROPAGATION IN EVAPORATION DUCT OVER THE ROUGH SEA SURFACE
RÉSUMÉ
In the previous investigations of centimeter wave propagation by the numerical stepwise partition method the scattering from the rough sea surface was taken into account in the tangent plane approximation. Such an approach prevents from taking into account the lighted surface shadowing and deviation of the sea surface height probability distribution from the normal law. The given work is concerned with the methods of registration of these effects and dependences of the attenuation factor on the height and distance in the presence of the evaporation duct. It is shown that shadowing exerts significantly greater impact on the centimeter radio waves propagation in the evaporation duct as compared to registration of the non-gaussianity. The obtained results make it possible to increase the precision prediction of the waves propagation in the lower troposphere.
