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.

请首先从以下网址下载船体辐射噪声样本（"samples.zip"）：http://atlanttic.uvigo.es/underwaternoise/（或http://atlanttic.uvigo.es/underwaternoise/samples.zip）。之后，您需要解压"samples.zip"并将所有*.wav文件复制到您的Matlab工作目录中。代码已在Matlab r2018b版本上进行了测试。至少需要4GB的可用ROM，以及8GB或更多的RAM。该工作可能需要数日时间（大约两天在i7 2.6 GHz核心处理器上），请耐心等待，这是值得投入时间的，只需让它独立运行即可。或者，您可以直接查看*.emf文件中的结果。
