METHOD FOR STEERING A TOWED ACOUSTIC LINEAR ANTENNA

摘要

A method and apparatus are provided for steering a first acoustic linear antenna belonging to a plurality of acoustic linear antennas towed by a vessel. A plurality of navigation control devices are arranged along the plurality of linear antennas in order to act at least laterally on the position of the linear antennas. At least one of the navigation control devices arranged along the first acoustic linear antenna performs steps of: obtaining a local measurement of a feather angle or of a parameter linked to the feather angle, the local measurement being associated with the at least one of the navigation control devices arranged along the first acoustic linear antenna; computing a lateral force, as a function of the obtained local measurement; and applying the computed lateral force.

1. A method for steering in water a master acoustic linear antenna, the method comprising:
calculating, in at least one navigation control device attached to the master acoustic linear antenna, a local measurement of (i) a feather angle or (ii) a parameter linked to the feather angle; obtaining a feather angle set point; and controlling, based on the local measurement and the feather angle set point, a lateral force applied by the least one navigation control device to the master acoustic linear antenna.
