LOW FREQUENCY TRANSIENT LOCALIZATION BY SONOBUOY ARRAYS

IT IS PROPOSED THAT A COMPUTER CODE BE DEVELOPED WHICH WILL LOCATE AND DEDUCE THE SIGNATURE OF LOW FREQUENCY TRANSIENTS BY SPARCE SONOBUOY ARRAYS. IT WILL BE ASSUMED THAT WE KNOW THE PROPERTIES OF THE PROPAGATING MEDIUM AND THAT IT IS HORIZONTALLY STRATIFIED. THE ALGORITHM WILL HAVE FOUR PARTS: 1) A DETECTION SCHEME, 2) A CORRELATION ROUTINE TO DETERMINE TIME DELAYS, 3) A ROUTINE TO DETERMINE LOCATION USING THE TIME DELAYS, AND 4) A ROUTINE TO DETERMINE THE TRANSIENT SIGNATURE AT THE SOURCE LOCATION. PERFORMANCE OF THE ALGORITHM WILL BE DETERMINED AS A FUNCTION OF TRANSIENT TYPE, OCEAN PARAMETERS, AND SONOBUOY ARRAY GEOMETRY.
