Spectral and correlation characteristics of fluctuations of a point radiation source bearing under strong effect of a sea surface in W-band range

Results of experimental investigation of amplitude interference-fading and angular fluctuation of a point source near a sea surface are discussed. The analysis enables one to come to the conclusion that on sliding propagation along the line-of-sight sea path, even in the case of a strongly rough surface, there is a rather high probability of existence of the limited number of quasi-mirror reflections. In this paper the main results of experimental investigation of statistical characteristics of amplitude and arrival angle fluctuation of detecting and direct 3 mm-band signals are reported, related to the case of over sea propagation with sliding angles from 1 to 10 mrad (distances from 300 m to 5000 m).
