Hierarchical Cosine Similarity Entropy for Feature Extraction of Ship-Radiated Noise
The classification performance of passive sonar can be improved by extracting the features of ship-radiated noise. Traditional feature extraction methods neglect the nonlinear features in ship-radiated noise, such as entropy. The multiscale sample entropy (MSE) algorithm has been widely used for qua...
