Abstract
THE PROPOSED EFFORTS ARE DIRECTED AT DEVELOPING AND APPLYING AN INNOVATIVE APPROACH TO AUTOMATIC DETECTION, CLASSIFICATION, AND LOCALIZATION FOR DISTRIBUTED SENSOR FIELDS IN CONTACT WITH PASSIVELY RADIATED ACOUSTIC SIGNALS FROM PLATFORMS OF INTEREST TO NAVAL SURVEILLANCE. THE APPROACH EXPLOITS THE NATURAL PHYSICAL PHENOMENA WHICH GOVERN ACOUSTIC SIGNAL PROPAGATION AND BOUNDARY INTERACTION IS ORDER TO AUTOMATICALLY FORM CORRELOGRAM SIGNATURES WHICH SIMULTANEOUSLY PROVIDE THE BASIS FOR AUTOMATIC DECLARATION OF DETECTION AND ESTIMATION OF CONTACT DEPTH AND RANGE. THE APPROACH IS NOVEL INSOFAR AS IT ATTEMPTS TO CROSS-CORRELATE TWO-DIMENSIONAL FILTERED ENHANCED CORRELOGRAMS DEVELOPED FROM THE GENIUNE SIGNAL DATA WITH A SET OF PREDICTED CORRELOGRAM SIGNATURE TEMPLATES WHICH CHARACTERIZE ALL FEASIBLE CONTACT-SENSOR SYSTEM SCENARIOS FOR THE PREVAILING ENVIRONMENTAL CONDITIONS AND KNOWN REGIONAL BATHYMETRY. CORRELOGRAM FEATURES ARE CAUSED BY SIGNAL ARRIVAL PATH DIVERSITY WHICH, FOR A GIVEN TARGET STATE ARE ABSOLUTELY DETERMINED BY THE NATURAL PHENOMENA GOVERNING SOUND TRANSMISSION AND BOUNDARY INTERACTIONS.
