Data for: Integrated Optimization of Underwater Acoustic Ship-Radiated Noise Recognition based on Two-dimensional Feature Fusion

Ship-radiated noise samples (”samples.zip”) should be firstly downloaded at: http://atlanttic.uvigo.es/underwaternoise/ (or http://atlanttic.uvigo.es/underwaternoise/samples.zip). And you need to unzip ”samples.zip” and copy all the *.wav files to your Matlab working directory. Code was tested on Matlab r2018b. At least 4 GB ROM should be available, and 8GB RAM or more is needed. This work may take a few days (about two days on i7 2.6 Ghz core), please be patient, it worth spending time on it, just leave it alone. Or you can directly see the results in *.emf files.
