Diffraction model of multiple-ray propagation above a rough surface at low grazing angles

On the basis of diffraction by wedge-like crests we present a theoretical interpretation of the peculiarities of millimeter and centimeter radiowave fields above a rough surface, in particular, a sea surface, that are experimentally observed when the elevation of one of the corresponding points is comparable with surface roughness heights.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Radiofizika, Vol. 39, No. 5, pp. 547–558, May, 1996.
