<p>Our data set contains five subsets, which are Seadata, RCSdata, RD_SeaImage, BP_SeaImage and SSHdata. Seadata is the data of simulated sea. RCSdata is the data of sea surface backward scattering coefficient. RD_SeaImage is the simulated images of sea surface. BP_SeaImage is the simulated images of sea surface. SSHdata is the sea surface height data.</p>
