Abstract
Computing device, system and method for calculating a far-field signature of a vibratory seismic source. The method includes determining an absolute acceleration of a piston of the vibratory seismic source while the vibratory seismic source generates a seismic wave; calculating, based on the absolute acceleration of the piston, a far-field waveform of the vibratory seismic source at a given point (O) away from the vibratory seismic source; and cross-correlating the far-field waveform with a driving pilot signal of the vibratory seismic source to determine the far-field signature of the vibratory seismic source.
