Method and System for Detecting Objects at or Below the Water's Surface.

Abstract

A method and system are provided for detecting objects at or below a surface of a body of water. A focused beam of amplitude varying electromagnetic radiation, e.g., a pulsed laser beam, is directed through the air towards the water's surface. Acoustic energy under the water's surface is monitored for any acoustic return that may be generated in the water as a result of the beam being incident on either an object at the water's surface or the water's surface above an object.
