Abstract: A system and method for reconstructing an incomplete data subset in seismic exploration is disclosed. The method includes receiving data based on a first emitted signal as a complete dataset. The first emitted signal is a range of frequencies between a starting frequency and a stopping frequency. The method further includes receiving data based on a second emitted signal as an incomplete data subset. The second emitted signal is a subset of the frequencies used by the first emitted signal between the starting frequency and the stopping frequency. The method further includes creating a reconstructed dataset by supplementing the incomplete data subset with the complete dataset and generating a seismic image based on the reconstructed dataset.
