Computation of Signal Strength at Low Frequencies and S/N Ratio Estimates for Broadband Marine Acquired Streamer Data

Various marine acquisition geometries designed for de-ghosting are evaluated with regard to recording signal strength and S/N ratios. The different de-ghosting methods used currently in exploration are not discussed. However, by examining the ghost operators with different acquisition geometries , we can estimate the recorded signal strength before de-ghosting and we can estimate changes in S/N ratios resulting from a de-ghosting method.
