Abstract
Embodiments described herein provide a method for acquiring de-ghosted data that can be utilized for calibration of a seismic source (air gun) model. Positions of a plurality of seismic receivers can be determined to enable efficient removal of an interference effect of ghost signals originating from mirrored versions of at least one seismic source that are received at the plurality of seismic receivers (hydrophones). Data (de-ghosted or near de-ghosted) can be acquired from the plurality of seismic receivers located at the determined positions by operating the at least one seismic source. A calibrated model of the at least one seismic source can be prepared based on the acquired (de-ghosted) data.
