SYSTEM AND TECHNIQUE TO SUPPRESS THE ACQUISITION OF TORQUE NOISE ON A MULTI-COMPONENT STREAMER |
摘要 |
<p>A technique includes receiving particle motion data acquired by particle motion sensors while in tow. The particle motion data are indicative of a seismic signal and a torque noise, and the particle motion sensors are oriented to modulate a wavenumber of a first component of the torque noise away from a signal cone that is associated with the seismic signal. The technique includes estimating the first component of the torque noise and based at least in part on the estimated first component, estimating a second component of the torque noise inside the signal cone. The technique includes suppressing the second component of the torque noise based at least in part on the estimated second component.</p> |
