1. A method for receiver deghosting seismic data related to a subsurface of a body of water, the method comprising: 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 r ) in the body of water; deriving a model domain describing the seismic data, the model domain being determined based on a function of linear operators that include a first operator representative of receiver re-ghosting, wherein the receiver re-ghosting introduces sea-surface ghost energy by multiplying the first operator with a reflection coefficient at the sea-surface, the linear operators reverse transform the model domain to obtain the seismic data, and the model domain is in a domain other than the time-space domain; using the derived model domain to remove receiver ghost from the seismic data to obtain deghosted seismic data by applying a second operator to the derived model domain; and generating a final image of the subsurface based on the deghosted seismic data.
