Coherent noise on seismic records is suppressed reformatting the common shot gathers (11, 13, 19) to common receiver gathers (31, 33, 35). Pair of seismic traces from a common receiver gather are corrected for differential normal moveout, weighted in inverse relation to the RMS signal power, and combined to generate compressed common receiver gathers. The compressed common receiver gathers may be reformatted as common midpoint gathers for further processing. |
