METHOD AND DEVICE FOR MEASURING SOURCE SIGNATURE

摘要

Source signature of a source array is measured using an autonomous underwater vehicle which is not physically connected to surface equipment and uses acoustic signals for communication and/or location. Such measurements may be performed while the source array is towed, the AUV then moving in tandem with the source array.

1. A method for acquiring a source signature of a towed source array, the method comprising:
deploying an autonomous underwater vehicle (AUV); controlling the AUV to maintain a position under the towed source array; detecting seismic waves emitted by the towed source array using seismic receivers carried by the AUV; and extracting the source signature based on the detected seismic waves.
