FIELD: physics.
SUBSTANCE: claimed system consists of the particle motion transducer, hydrophone, seismic event detector, means for adaptive processing of signals and means for signals subtraction. Claimed noise suppression process consists in measures that follow. Adaptive hydrodynamic model of hydrophone streamer is used to shape from the unprocessed signal from the particle motion transducer the transducer rated signal composed by the evaluation of underwater hydrophone streamer response to its displacement with no seismic events. To receive the hydrophone streamer noise-isolated response to seismic event, transducer rated signal is subtracted from unprocessed signal.
EFFECT: reduced influence of effects relates with hydrophone towing and underwater streams.
