Abstract: An empirical model of ocean surface wind speed and significant wave height relation is proposed by analyzing data obtained by buoy in-situ observations at the coverage of radar beam.The model′s parameters are estimated by minimum standard Euclidean norm method from six months′ buoy in-situ measuring data and the estimation results show the model′s stability.The wind and wave model is applied to HFSWR OSMAR071′s wind speed inversion.Compared with four months′ buoy in-situ observation wind speed,the correlation coefficient is 0.6 and the RMSE is 2.7 m·s-1 which confirmes the model′s availability,which verifies the validation of the empirical wind speed inversion.
