基于按风速分段法反演风速的研究,提出了一种海洋环境噪声估计风速的修正方法。该方法考虑了不同海域不同水声传播条件对风关环境噪声的影响,兼有判别雨、船等噪声源的功能。利用所提出修正法对中国近海某海域实测数据的处理表明,它可适用于不同海域,具有较好的鲁棒性。在有应用意义的中风速段(15 m／s>v>6 m／s)和高风速段(v>15 m／s),该方法反演风速的误差不超过15％,小于WOTAN法反演风速的误差。修正法为海洋环境噪声实时反演风速系统应用于近海不同海域提供了良好的基础。
Based on the research on the wind speed inversion by the wind speed segmentation method, a method to correct the wind speed of the marine environment noise is proposed. The method takes into account the influence of different conditions of underwater acoustic transmission in different seas on the noise of the customs environment and the function of distinguishing noise sources such as rain and ship. Using the proposed correction method to deal with measured data in a certain sea area of China offshore shows that it can be applied to different sea areas and has good robustness. The wind speed error of this method is less than 15%, which is smaller than that of WOTAN method (15 m / s> v> 6 m / s) and high wind speed The wind speed error. The correction method provides a good foundation for the real-time inversion of wind speed of marine environment noise applied to different sea areas.
