The statistical characteristics of the field of centimeter and millimeter waves above the sea surface

Experimental results are presented on the statistical characteristics of the direct signal field at 3.2 cm, and 8, 4, and 2 mm in the case of propagation above the disturbed surface of the sea at small grazing angles. It is shown that the distribution laws of the signal amplitude fluctuations on a short route (0.75 km) differ from the Rice and Rayleigh laws, which are more characteristic for long routes (16 km). Experimental and calculated values of the diffuse scattering coefficient at several values of the Rayleigh parameters are compared. Data on the spatial cross correlations of the amplitude fluctuations are analyzed, indicating that there is a significant anisotropy in the horizontal and vertical planes.
