US Patent:

48096385, Mar 7, 1989

Filed:

Nov 2, 1987

Appl. No.:

7/115299

Inventors:

Robert R. Kolesar - San Diego CA
J. Terry Richard - San Diego CA

Assignee:

The United States of America as represented by the Secretary of the Navy - Washington DC

International Classification:

G01D 2100

US Classification:

116 26

Abstract:

A method of and an apparatus for providing an all weather day and night ltion marker on the surface of a body of water enable optional visual, radar and IR detection to ensure the timely rescue of a disaster victim. A cohesive surfactant is mixed with an evaporation reducer and contained in a packet that allows the dispersing of a film made up of the two compounds after they are placed in the water. The film creates a surface that has a slick appearance with respect to the surrounding water, that has a reduced radar backscatter with respect to the surrounding water and which, as a result of reduced evaporative cooling, results in a local increase in the surface temperature with respect to the surrounding water to assure the visual, radar and IR detection.

Abstract:

An apparatus and technique reduces the data transmission rate required to ansmit acoustic signals from undersea sensors to remote monitoring locations without degrading the surveillance information content of the signals. The signals are digitized and fed to an adaptive line enhancer (Wiener filter) which processes them so that a fast Fourier transform (Karhunen-Loeve approximation) coefficient generator can feed representative signals to a programmable quantizer and a signal averager. When significant shifts are detected in the fast Fourier transform coefficient variances, responsive signals are generated by the programmable quantizer for adaptive bit allocation. An interconnected multiplexer transmits multiplexed signals to the remote monitoring station where the inverse of the foregoing allows an analysis of the acoustic signals being monitored.
