ABSTRACT:
A processing method for calibrating at least one pair of hydrophone-geophone sensors disposed on a water bottom and used in seismic prospecting processing in which a sound source emits a signal into the water and the sensors at the water bottom pick up hydrophone and geophone recordings H and G, wherein calibration is applied to the recordings to minimize, in a time window beyond a theoretical extinction time, the energy of a signal S which is determined as a function of the hydrophone and geophone recordings and which corresponds to the source signal propagated through the layer of water to the sensor.
