Multi-Stage Feature Extraction and Classification for Ship-Radiated Noise

Multi-Stage Feature Extraction and Classification for Ship-Radiated Noise

Due to the complexity and unique features of the hydroacoustic channel, ship-radiated noise (SRN) detected using a passive sonar tends mostly to distort. SRN feature extraction has been proposed to improve the detected passive sonar signal. Unfortunately, the current methods used in SRN feature extr...
