AZIMUTHAL NOISE VARIATION EXPLOITATION (AZNOVEX)

A SYSTEM IS PROPOSED FOR ASW PLATFORMS TO GENERATE AND DISPLAY THE AMBIENT NOISE LEVELS ABOUT THE AZIMUTH INDEPENDENT OF THE SENSORS OR THE SHIPS'S OWN RADIATED NOISE EFFECTS. THE PROPOSED AZIMUTHAL NOISE VARIATION EXPLOITATION (AZNOVEX) SYSTEM WOULD USE NOISE MEASUREMENTS MADE THROUGH THE SHIP'S ACOUSTIC SENSORS TOGETHER WITH MODELS OF THE SHIP'S RADIATED NOISE AND ACOUSTIC SENSOR PERFORMANCE TO DERIVE THE AMBIENT NOISE PROFILE. DISPLAYS AND UPDATES WOULD SUPPORT DETECTION AND COUNTERDETECTION VULNERABILITY ASSESSMENTS IN ALL PHASES OF ANTI-SUBMARINE WARFARE. THE SYSTEM WOULD RECOMMEND OWNSHIP MANEUVERS AND FREQUENCY OF OWNSHIP MANEUVERS BASED ON THE ENVIRONEMENT AND TACTICAL SITUATION.
