The effect of varying grazing angle on the Doppler spectra of radar backscatter from wind waves has been investigated in a laboratory wave tank. Five different radar frequencies were used and six different wind conditions, for a range of grazing angles between 3° and 24°. The results show linear relationships between the velocity of the dominant scattering components and the grazing angle. This effect is hard to reconcile with a scattering mechanism based on Bragg resonance. Data from a cliff-top radar were also examined.
