Physical processes of microwave backscattering from wind wave surfaces are investigated in a wind wave tunnel by using a X-band (9.6 GHz) microwave scatterometer. Detailed analysis of time series of the backscattered intensity and Doppler spectrum shows that the physical processes of microwave backscattering are closely associated with the processes of the wind wave field. The fine structures of wind wave surfaces, which are trapped near the crests and propagating with the crests, are the main contributor to microwave backscattering. It is also pointed out that the effect of wave breaking with bubble entrainment on the microwave backscattering is not significant under the condition of the present experiment. -from Authors
