Abstract:

The report comprises three sections. Section A, entitled Laser Detection of Submarine Signatures, discusses the fundamentals of mechanical wave propagation in the sea both for transverse-type waves and for longitudinal-type waves, and the corresponding surface-wave distributions these characterize respectively the optical signature and the acoustic signature of submarines and torpedoes. Two separate methods which utilize laser techniques for readout of such signatures are described experimental results of the investigation pertaining to readout of the acoustic signature are presented. Section B discusses a method of detection of the optical signature of submarines and torpedoes using a pulsed infrared laser beam for illumination of the sea surface, gating techniques for extended range operation, TV-type image display of the sea surface, automatic readout by spatial filtering techniques. Section C discusses a method of two-way communication between an airplane and a submerged submarine using laser and sonar collimated beams to write and to readout messages on the sea surface.
