- W2381653177 abstract "A new method of line spectrum feature extraction in ship radiated noise power spectrum was proposed based on partial least-square curve fitting.A new coordinate transform and the least-square curve fitting were used to extract the continuous spectrum feature.The continuous spectrum feature and the line spectrum feature are combined as the power spectrum feature of ship radiated noise.The classification recognition experiment for two different classes of target noises in the sea was performed with BP neural network,and the results show that the method is effective with a recognition rate over 90%." @default.
