Abstract
A propagation model is offered for description of the microwave field over the rough sea surface at low grazing angles and in large shadowing on the area below the limit of application of the tangent plane approximation. Analysis is made on the distance dependence of the reradiated field intensity and characteristic coherent and random components for few variants of the sea state and the height of corresponding (transmitting and reception) points. It is shown that for wide grazing angles the results of calculation by the method offered and by the method of tangent plane approximation coincide.

KEY WORDS:microwave field, sea surface, low grazing angle, edge diffraction, reflection from cylinders
