ABSTRACT:
A method for using signals measured by pressure responsive seismic sensors and motion responsive seismic sensors disposed in a seismic cable includes simulating a selected range frequency response of the motion responsive sensor signals for each of a plurality of selected depths in a body of water. For each sensor position along the streamer, the one of the simulated selected frequency range responses is selected for which the selected depth most closely matches an actual sensor depth. The selected simulated selected range frequency responses are combined with the measured motion responsive sensor signals to produce full bandwidth motion responsive signals. The full bandwidth signals are combined with the pressure responsive signals to determine at least one of an upgoing and downgoing pressure or motion wavefield.
