Abstract

Il est décrit un système de projecteur acoustique sous-marin comprenant un ensemble linéaire de projecteurs acoustiques situés à proximité les uns des autres, de telle sorte quils interagissent entre eux lorsquils produisent des pressions acoustiques. Chaque projecteur acoustique dans lensemble linéaire est à lécart dun projecteur acoustique adjacent. La distance entre deux projecteurs acoustiques à proximité du centre de lensemble linéaire est plus important que la distance entre deux projecteurs acoustiques à proximité de lextrémité de lensemble linéaire.
