Underwater Object Detection System.
Abstract
Propagation of modulated radiation from a platform is substantially limited to unidirectional transmission through a body of water. Acoustical energy is generated at the surface of a remote object submerged in the water in response to impingement and absorption of the modulated radiation from the platform. Radiation of the acoustical energy generated adjacent the object is detected at the platform to extract data therefrom from which the location of the object relative to the platform is indicated. Patent applications. (jhd)
