Abstract: A method is presented to reduce the quantity of microbubbles having diameters of approximately 1000 microns or less in seawater as a means of ship wake signature suppression. Ultrasonic acoustic energy is projected into a volume of seawater in which the microbubbles reside. e.g.. a ship's wake. The ultrasonic acoustic energy has a constant frequency selected from the range of approximately 0.5-2.5 MHz.
