Abstract
THIS PROPOSAL DESCRIBES A SPECIFIC CONCEPT FOR SUBMARINE TRAINING MINEFIELD REALTIME TRACKING, INCLUDING PULSE LENGTHS, BANDWIDTHS, SEQUENCES AND SYSTEM LOGIC; ALTHOUGH WE DO NOT KNOW THE MINEFIELD DIMENSIONS, PREVALENT SVPS, BOTTOM REFLECTIVITY, ETC. THESE MAY NECESSITATECHANGES IN THE PARAMETERS, BUT STARTING WITH A SPECIFIC DESIGN WHICHWE CAN ANALYZE, EVALUATE, AND ADAPT DURING PHASE 1, WE ARE CERNTAIN TO ENTER PHASE 2 READY TO CONSTRUCT A PROTOTYPE. THIS CONCEPT IS ENVIRONMENTALLY TOLENT, PARTICULARLY TO REVERBERATION AND PULSE SPREADING. EACH OF THE 10 TRANSPONDERS TRANSMITS ONLY A SINGLE PING, AT ITS ASSIGNED FREQUENCY, AS DOES THE SUBMARINE. EACH LISTENS AT ALL 11 FREQUENCIES AND DETERMINES WHICH TRANSMITTER IT HEARS. THE DISTANCE BETWEEN SUBMARINE AND TRANSPONDERS IS UPDATED MORE THAN THAT BETWEEN TRANSPONDERS. THE ACCURACY IS 1 YARD, BUT MIGHT BE IMPROVED. THE WORK PLAN IS DESCRIBED IN RELATION TO THE COMONENTS OF THE PROPOSED SYSTEM AND QUESTIONS WHICH REQUIRE RESOLUTION. IT INCLUDES BUILDING AN AIR SIMULATION USING MICROPHONES AND SPEAKERS TO CHECK THE LOGIC AND RELATED COMONENTS OF THE TRANSPONDERS. MANDEX AND ITS PERSONNEL HAVE EXTENSIVE EXPERIENCE WITH TRANSPONDERS, LOGIC CIRCUITS, UNDERWATER ACOUSTICS, AND OTHER SYSTEM ELEMENTS.
