We propose a new processing approach not only to correct but to exploit the effects of the motion of marine vibratory source deployed an offshore seismic survey. We decompose the survey data into plural sections as a function of time, space and signal frequency. The instantaneous spatial locations of shot/receivers as a function of time and signal frequency are used in the data processing. Our processing method is applied to numerical simulation data for a moving source generating a waveform of a finite time duration encoded with a frequency sweep, and to a marine seismic reflection survey data acquired by a mechanical-driven marine seismic vibrator that was designed to verify its feasibility. We found it is possible to remove the source motion effect by applying our processing approach with the conventional migration processing. Furthermore, we perceived the enhancement of the lateral resolution after taking the motion of the source into account in marine vibrator survey. The utilization of marine vibratory sources has the potential to realize high accuracy survey when exploiting the continuity in time and space for seismic emission.
