Abstract
A method for determining water bottom reflectivity in dual sensor seismic surveys is disclosed. The method eliminates the need for a separate survey to collect calibration data. The method involves summing the pressure and velocity signals, and multiplying the result by the inverse Backus operator, and then solving for the ocean bottom reflectivity R utilizing an optimization algorithm. Also disclosed is a method for combining the dual sensor data which results in the complete elimination of the first order peg-leg multiples and the modulation of the sub-surface reflector strength with the ocean bottom reflectivity. The method involves summing the pressure and velocity signals, and multiplying the result by the inverse Backus operator containing the correct value for the ocean bottom reflectivity R found with the method described above.
