Inversion of Non-Equivalent Sound Velocity Profile Based on BP Neural Network
The inversion of sound velocity profiles based on historical data is a method in marine environmental acoustic tomography.Traditional sound velocity profile inversion methods are difficult to obtain non-equivalent sound velocity profiles in large areas of the sea,and the results obtained are generally equivalent sound velocity profiles.To address this issue,a non equivalent sound velocity profile inversion method based on Back Propagation(BP)neural network is proposed.The comparison results show that this method can effectively invert non equivalent sound velocity profiles and the inversion results have higher accuracy compared to traditional sound velocity profile inversion.
