Abstract:

A method and apparatus to clear mines uses tag particles dropped into ambient water across a wide area by an aircraft to sink and stick to submerged mines. The tag particles each contain a gas volume dimensioned to resonate with impinging acoustic energy and reflect portions of the impinging acoustic energy from a targeted mine. An unmanned underwater vehicle platform having a sonar system provided with at least one transducer projects the acoustic energy through the ambient water. At least one hydrophone transducer in the sonar system receives the reflected portions of the projected acoustic energy to locate a targeted mine t enable its destruction by high-energy supercavitating projectiles fired from the platform. Tag particles dissolve after a period of time to provide virtually no discernable traces of a mine hunting operation.
