【摘要】 海洋环境噪声与海面风速高度相关。本文在研究国内近年来测量数据的基础上，给出环境噪声级与风速的关系。提出按风速分段（三段）线性拟合环境噪声与对数风速关系曲线的方法，提出并确定最佳反演频段。在麦岛海域，由实测数据确定了分段拟合参数，获得在 ０．１～ ２２．６ ｍ／ｓ的风速范围内，由海洋环境噪声估计海面风速的误差在 １０％以下的优良结果。更多还原

【Abstract】 The ocean ambient noise is highly correlated with surface wind speed. The relation between the ambient noise and the wind speed has been derived based on the measurements made in recent years. We have proposed a new multi-section method to linearly fit the relation between ambient noise and the logarithm of wind speed respectively in different wind speed sections, and determined the best frequency band to perform the inversion operations. The multi- section fitting parameters are determined from the measured data at Maidao Sea, and satisfying results are obtained for estimating the the surface wind speed by ocean ambient noise, and all estimating errors are within 10% of the wind speed between 0.1 and 22.6 m/s.更多还原
