Controller and method for determining a driving signal of a vibro-acoustic source element that is configured to generate acoustic waves in water. The method includes estimating at least one physical constraint of the vibro-acoustic source element; setting a target energy spectrum density to be emitted by the vibro-acoustic source element during the driving signal; and determining the driving signal in a controller based on a frequency-dependent far-field sound pressure (P), the at least one physical constraint, and the target energy spectrum density, wherein the frequency-dependent far-field sound pressure (P) is calculated based on a free-field condition that assumes that waves emitted by the vibro-acoustic source element are not reflected at the water-air interface. |
