DATA ACQUISITION METHOD AND SYSTEM

摘要

Disclosed is a system for acoustically exploring structure of a floor below a water body. The system can comprise a vessel, at least one streamer placed in the water and towed by the vessel. The system can also comprise a plurality of acoustic sensors positioned at regular intervals along the length of the streamer. The longitudinal direction of the streamer can make an angle with the horizontal. The system can also comprise a source for generating acoustic pulses placed in the water and towed by the vessel using a tow line. The tow line can have such length that the horizontal distance between the vessel and the source is larger than the horizontal distance between the vessel and the first sensor closest to the vessel and smaller than the horizontal distance between the vessel and the last sensor most remote from the vessel.

1. A system for acoustically exploring structure of a floor below a water body, the system comprising:
a vessel; at least one streamer placed in the water body and towed by the vessel and comprising a plurality of acoustic sensors positioned at regular intervals along a length of the streamer, wherein a longitudinal direction of the streamer forms an angle with a horizontal direction; a source for generating acoustic pulses and being placed in the water body and towed by the vessel; and a tow line connecting the source to the vessel; wherein the tow line has such length that a horizontal distance between the vessel and the source is larger than a horizontal distance between the vessel and a first sensor closest to the vessel and smaller than a horizontal distance between the vessel and a last sensor most remote from the vessel.
