摘　　要：基于风向多波束法的思想,该文提出了一种新的多波束法实现方式—最小二乘多波束法,解决了传统实现方式可能存在的波束没有交点的问题。将此方法应用到高频地波雷达OS081H的风向反演中,并与实测数据进行了对比,表明该方法可有效地消除风向模糊。同时,通过与最大似然法的结果进行比较分析,并考虑了风速对风向反演的影响,结果发现,风速越大风向反演结果的相关性和精度越好。Based on the idea of the multiple beam method, the least squares multi beam method is developed to resolve the problem that there is no intersections between beams by the traditional means of implementation . The method is used to process the data obtained from the OS081H high frequency surface radar system and the results are compared with the data obtained from automatic meteorological station. It is showing that this method can eliminate the wind direction ambiguity. In addition, the results are compared with the data obtained by the maximum likelihood method and the effect of wind speed on the accuracy of inversion is discussed. The results show that the correlation and accuracy improves as wind speed increases.
