摘　　要：从高频地波雷达回波谱中反演有效波高的Barrick模型是工程中实用性较强的模型,为了进一步提高有效波高的反演精度,提出了改进的三参数模型,在模型中增加了调节参数,以提高模型的拟合程度。将改进模型应用到了高频地波雷达有效波高的反演中,并与浮标数据进行了比对,二者的相关系数和均方根误差分别为0.81和0.42m。同时,将改进模型与已有的模型进行了比较分析,结果表明所提出的改进模型对有效波高的反演结果较之已有模型有所改善。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 de- gree 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.
