US PATENT 7,206,257
Acoustic remote caviation as a destruction device
Abstract
A method is disclosed of generating a predetermined field of cavitation around a remote target in an underwater environment. The method includes the steps of identifying a remote target location, generating at least two acoustic beams, each at a high power output, from an underwater acoustic source, and controlling the generated acoustic beams to intersect with each other at the remote target location and thereby create a destructive cavitation field at the intersection of the beams. The acoustic source and target can be located in unconfined underwater space and at a distance of at least 100 m apart.
RANGE
The underwater object targeted for destruction ...........may include mines, incoming torpedoes, marine fouling barnacles, and emergency rescue operations. It will be understood that the position of the underwater object .... is not necessarily specifically identifiable, yet is within a range of about 100 meters to about 1 Km from a source vessel such as a submarine
