<p>A marine seismic reflection prospecting method and system in which coherent noise is attenuated through reinforcement of primary reflection data by the addition of corrected ghost reflection data. The system includes a seismic energy source, a detector, a wavefield separator, a time-shift element, and an element for generating an output signal representative of an additive linear combination of time-aligned primary and ghost signal components. The system's output is suitable for further pre-stack processing, e.g. NMO correction.</p> |
