Ship Radiated Noise Modulation Feature Extraction Based on CEEMD and Wavelet Threshold Noise Reduction
Ship propeller beats have obvious amplitude modulation to the cavitation noise of its radiation. The DEMON (Detection of Envelope Modulation on Noise) spectrum analysis technology is to demodulate the high frequency components to get the low frequency modulation components. This paper studied the new method to combine the complementary ensemble empirical mode decomposition (CEEMD) with wavelet ...
متن کاملFeature Extraction of Ship-Radiated Noise Based on Permutation Entropy of the Intrinsic Mode Function with the Highest Energy
Abstract: In order to solve the problem of feature extraction of underwater acoustic signals in complex ocean environment, a new method for feature extraction from ship-radiated noise is presented based on empirical mode decomposition theory and permutation entropy. It analyzes the separability for permutation entropies of the intrinsic mode functions of three types of ship-radiated noise signa...
متن کاملA Novel Feature Extraction Method for Ship-Radiated Noise Based on Variational Mode Decomposition and Multi-Scale Permutation Entropy
Abstract: In view of the problem that the features of ship-radiated noise are difficult to extract and inaccurate, a novel method based on variational mode decomposition (VMD), multi-scale permutation entropy (MPE) and a support vector machine (SVM) is proposed to extract the features of ship-radiated noise. In order to eliminate mode mixing and extract the complexity of the intrinsic mode func...
متن کاملShip-radiated noise feature extraction using multiple kernel graph embedding and auditory model
The analysis of underwater acoustic signals, especially ship-radiated noise received by passive sonar, is of great importance in the fields of defense, military, and scientific research. In this paper, we investigate multiple kernel learning graph embedding using auditory model features in the application of ship-radiated noise feature extraction. We use an auditory model to get auditory model ...
متن کاملNoise reduction of ship-radiated noise based on noise-assisted bivariate empirical mode decomposition
Underwater acoustic signal has the non-linear and non-stationary characteristics. Aiming at the issue on noise reduction of underwater acoustic signal, an adaptive noise reduction method of ship-radiated noise based on noiseassisted bivariate empirical mode decomposition is proposed. Firstly, a two-dimensional complex data is built by using one-dimensional real signal and adding Gaussian white ...
