中文摘要: |
利用舰船噪声进行地声参数反演是近年来的热门研究课题之一。目前大多数利用舰船噪声的反演方法依赖于多参数海底模型,而多维参数的求解加大了反演的复杂度,因此,基于海底单参数模型,提出一种使用舰船噪声作为声源的海底单参数反演方法。基于实验数据进行海底单参数反演,并用反演得到的结果,对实验海域的传播损失进行预报。最后,对海底单参数与频率的关系进行了拟合和研究,验证了反演方法的有效性。 |
英文摘要: |
In recent years, the ship noise based geo-acoustic inversion is one of the hot research topics. At present, most inversion methods using ship noise rely on multi-dimensional seabed models, which increase the complexity of inversion. Therefore, based on the single seabed parameter model, a single seabed parameter inversion method by using ship noise as sound source is proposed. Based on the experimental data, the single seabed parameter is inverted, and by which, the transmission loss in the experimental sea area is predicted. Finally the relationship between single seabed parameter and frequency is fitted and studied, and the effectiveness of the inversion methods is verified. |
