Evaluation of the relationship between parameters of the radar signal backscattered by the sea surface at grazing angles and the wind wave breaking characteristics
Authors:V V Malinovsky
Abstract:The results of investigations of the statistical characteristics of spikes of radar signals scattered by the sea surface at grazing angles and borizontally polarized radiation are reported. The measurements were conducted at wind speeds ranging from 2.8 to 9 m s–1 and at various azimuthal directions relative to the general sense of wind wave propagation. The relationship between the theoretically and experimentally derived distribution parameters allows a conclusion about the linear dependence of spike amplitudes on the extent of instable areas. The theoretical model provides a qualitatively authentic azimuthal nature of the variation of the mean radar signal.Translated by V. Puchkin.
