    摘要: A technique includes receiving data indicative of non-uniformly spaced samples of particle motion wavefield acquired by particle motion sensors while in tow. The samples are spaced apart by an average spacing interval, which is not small enough to prevent vibration noise from being aliased into a signal cone for a first signal formed from samples of the particle motion wavefield having a uniform spacing at the average spacing interval. The technique includes processing the data to generate a second signal that is indicative of the particle motion wavefield and does not have aliased vibration noise in the signal cone.

    摘要: 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.

    摘要: A technique includes distributing particle motion sensors along the length of a seismic streamer. Each particle motion sensor is eccentrically disposed at an associated angle about an axis of the seismic streamer with respect to a reference line that is common to the associated angles. The sensors are mounted to suppress torque noise in measurements that are acquired by the particle motion sensors. This mounting includes substantially varying the associated angles.
