A METHOD FOR DETERMINING THE LOCATION OF DEEP-OCEAN ACOUSTIC SOURCES,
Abstract
A concept and method were developed by which a vehicle can determine the location and acoustic source level of deeply submerged acoustic projectors. This concept was tested by using an acoustic source whose location and output level were known. A distribution of such known sources would provide a navigation system. The method for locating the position of an unknown source is essentially the solution of triangulation equations by use of the time difference in the arrivals of the direct and surface reflected acoustic pulses. Usually three measurement stations are to be chosen in a triangular pattern with distances between the stations of at least 5 miles. An application of this method is feasible in concept as a passive ranging system in certain types of ASW situations. (Author)
