A COMPARATIVE STUDY OF FOUR NONLINEAR DYNAMIC METHODS AND THEIR APPLICATIONS IN CLASSIFICATION OF SHIP-RADIATED NOISE

A comparative study of four nonlinear dynamic methods and their applications in classification of ship-radiated noise

Refined composite multi-scale dispersion entropy (RCMDE), as a new and effective nonlinear dynamic Fleeces method, has been applied in the field of medical diagnosis and fault diagnosis.In this paper, we first introduce RCMDE into the field of underwater acoustic signal processing for complexity feature extraction of ship radiated noise, and then p
