Near-vertical high-rate adaptive communication from sub-sea platforms

Objective



THE NEAR-VERTICAL ACOUSTIC COMMUNICATION LINK IS OF GREAT PRACTICAL IMPORTANCE IN OCEANOGRAPHY AND MARINE ENGINEERING. IT PROVIDES THE MOST DIRECT WAY OF TRANSMITTING DATA FROM OCEANOGRAPHIC INSTRUMENTATION,WELL-HEAD EQUIPMENT AND ROV TELEMETRY SYSTEMS. THE VERTICAL LINK CAN BE RELATIVELY FREE FROM MULTIPATH INTERFERENCE BUT IS CONTAMINATED BY SURFACE NOISE. ALTHOUGH THE APPLICANTS HAVE CONSIDERABLE EXPERIENCE IN THE ENGINEERING OF SUCH LINKS, MANY QUESTIONS STILL NEED TO BE ANSWERED. MOST PARTICULARLY, AN APPRECIATION IS REQUIRED OF THE BALANCE BETWEEN THE ENERGY BUDGET OF A SEA-FLOOR EQUIPMENT AND THE PROPORTION OF UNCORRUPTED DATA WORDS PASSING THROUGH THE LINK, UNDER A RANGE 0F ENVIRONMENTAL CONDITIONS.
THIS RESEARCH IS INTENDED TO PROVIDE: NEAR VERTICAL ACOUSTIC TRANSMISSION FOR ALL OCEAN DEPTHS, INTEGRATED RADIO RETRANSMISSION CAPABILITY; APPROPRIATE DEPLOYMENT AND DATA RETRIEVAL TECHNOLOGY INCLUDING THE USE OF LOW-COST SONOBUOY TECHNIQUES; ULTRA-HIGH DATA RATES STEMMING FROM OCTAVE-BAND TRANSDUCER CAPABILITY; FIXED AND MOBILE PLATFORM CAPABILITY; DUPLEX TRANSMISSION FOR ADAPTIVE CONTROL OF THE TRANSMITTER, OPTIMAL ENERGY UTILISATION. SPECIFIC DELIVERABLES WILL INCLUDE: DEMONSTRATOR EQUIPMENTS; EXHAUSTIVE LINK TESTS; DATA ON NEAR-SURFACE NOISE; THEORETICAL PERFORMANCE ASSESSMENT.
