Determining An Orientation Angle of A Survey Sensor |
| 摘要 |
Measurement data acquired by at least one sensor in a cable structure towed through a body of water is received. A torsional vibration noise component in the measurement data is estimated. The torsional vibration noise component is used to estimate a rotation angle of the at least one survey sensor with respect to a reference coordinate system of the cable structure. |

1. A system comprising:
a storage medium to store measurement data acquired by at least one survey sensor in a subterranean survey operation, wherein the at least one survey sensor is in a cable structure for towing through a body of water; and at least one processor to:
estimate a torsional vibration noise component in the measurement data; anduse the torsional vibration noise component to estimate a rotation angle of the at least one survey sensor with respect to a reference coordinate system of the cable structure. |
