Using an HF skywave radar to study the decametric sea waves, it appears that their amplitudes do not saturate as the wind speed increases. A measurement method, based on the Kahma sea wave spectrum, is proposed and radar estimations of the wind speed are compared with in situ measurements performed on board a ship. The rms difference between the two measurements is 2.5m/s and is probably mainly due to the spatial variability in the wind speed.
