摘要
Systems and methods to determine a deghosted wavefield are described. In one aspect, the method computationally transforms recorded wavefield data from the space-time domain to a spectral domain and computationally deghosts the wavefield data in the wavenumber-frequency domain based on iterative minimization of a cost functional. The deghosted wavefield data may be transformed from the spectral domain back to the space-time domain and stored.
