Abstract:

The Barrick’s model of significant wave height inversion is a relatively practical model for the highfrequency surface wave radar (HFSWR) sea echoes. For improving the inversion accuracy of the significant wave height, a three-parameter model is proposed, in which a modulation parameter is added to improve the degree of fitting. The significant wave heights inversed by applying the model to data obtained from HFSWR are compared with the buoy values. The correlation coefficient between the radar inversed and those of the buoy is 0.81, and the mean square root error (RMSE) is 0.42 m. Meanwhile, the modified model and other models are compared and analyzed, and the results show that the significant wave heights obtained from the modified model are slightly better than other models.
