Abstract

In order to solve the problem of active sonar pulse interference existing in ship radiated noise signal, this paper uses Variational Mode Decomposition to decompose the ship radiated noise signal containing pulse interference into multiple Intrinsic Mode Functions. The interference modes are screened out by the relative maximum method, and the effect of the algorithm is evaluated by mean square error and correlation coefficient. The simulation results show that the proposed method can effectively suppress the active sonar pulse interference in ship radiated noise and has a certain robustness. The results of this paper can be used for data preprocessing before underwater acoustic target recognition, and have a certain role in improving the effectiveness of underwater acoustic target recognition.
