Abstract
In order to observe temporal distribution of sea clutter, radar echoes were taken from high sea state 7 at a fixed azimuth angle of 317 degrees. It is shown that the sea-clutter amplitudes obey the Weibull distribution at a g razing angle of 3.9 degrees, and obey both the Weibull distribution and K-d istribution at grazing angles of 7.5 degrees and 61.4 degrees. As the grazi ng angle increases, the shape parameters of Weibull distribution and K-dist ribution increase with both the distributions themselves tending to be clos er to the Rayleigh distribution.
