摘要：

The free-surface related multiples of submarine seismic data are very serious. At present, the method to deal with such multiples is to combine the pressure component and vertical velocity component first and then use the conventional multiple suppression technology applied to tow-streamer data. In this paper, a multiple separation method for submarine seismic data on both sides is developed, that is, multiples on detection side are separated by P Z summation and then multiples waves on source side are separated by deconvolution of up-going wave and down-going wave. This method is fully data-driven and has the advantages of fast operation and high computational efficiency. Theoretical models verify the method and satisfactory separation effect is obtained.
