<p>Computing device, computer instructions and method for deghosting seismic data related to a subsurface of a body of water. The method includes receiving seismic data recorded by seismic receivers that are towed by a vessel, wherein the seismic data is recorded in a time-space domain and the seismic receivers are located at different depths (z) in the body of water; modeling the seismic data in a shot or common midpoint domain as a function of linear operators that re-ghost the receiver to derive a model; using the derived model to remove the receiver ghost from the seismic data to obtain deghosted seismic data; and generating a final image of the subsurface based on the deghosted seismic data. Figure 9 Receiving seismic data recorded by seismic receivers that are towed by a vessel Applying a Fourier transformation to the seismic data to transform it in seismic data d in a frequency-space domain Using a modified Radon transformation L to determine a tau-p transform p based on the seismic data d in the frequency-space domain Reverse-transforming the tau-p transform p to obtain deghosted data with a given datum Generating a final image of the subsurface based on the deghosted data with the given datum</p> |
