Dataset for Surface waves prediction based on acoustic backscattering

<p>Underwater acoustic measurements dataset is represented by three types of files &ldquo;.raw&quot;, &ldquo;.mat&quot;, &quot;.dat&quot; as follows:<br> * &ldquo;.raw&quot; format also represented by three types of data.<br> - &ldquo;...search.raw&quot; files contain complex envelop from all hydrophones calculated at four emitted frequencies<br> - &ldquo;...chan.raw&quot; files is a signal in a wide band from one of the hydrophones - for control and noise analysis.<br> -&nbsp;&nbsp;the largest files are the raw wideband signal from all hydrophones. One such file was saved per eight-hour sound emission cycle.<br> * Spectrogram files are saved in MATLAB format &ldquo;.mat&rdquo; v7 . Phasing of the antenna array (all-round view) and calculation of window spectra near each emitted pulse&nbsp;&nbsp;was carried out.<br> * &quot;.dat&quot; files contain features of the average spectrum of the backscattered signal.<br> * Direct measurements of surface wave characteristics, made by a Datawell DWR-G4 wave-rider buoy, accompanied the acoustic measurements. This data is included too.</p> <p>In this archive, we upload all available files of the &quot;dat&quot; and &quot;mat&quot; type and a limited number of &quot;raw&quot; files. You may unpack all &quot;.tar.gz&quot; files into one folder, preserving the directory tree, existing in the archives.</p> <p>Users should refer to the included &ldquo;.pdf&rdquo; file for the data format description and to a published preprint for a description of the experimental conditions and instrumentation characteristics.

Data acquisition would be impossible without their contribution.&nbsp;This research was supported by the Russian Science Foundation, grant number 20-77-10081 (the expedition and motivation for study) and the State Contract with the Ministry of Education and Science of the Russian Federation, grant number 0030-2021-0017 (the instruments for underwater acoustic measurements).</p>
