A BROADBAND HIGH-FREQUENCY ANTENNA STRUCTURE FOR THE TACAMO AIRFRAME WAS STUDIED. THE STRUCTURES STUDIED WOULD NOT DEGRADE AERODYNAMIC PERFORMANCE AND WOULD ALLOW MULTIPLE TRANSMITTER OPERATION OVER THE FULL 2 TO 30 MHZ BAND. EVALUATION FACTORS WERE EFFICIENCY, BANDWIDTH, MINIMUM LOSSES, LOW RESISTANCE, AND MINIMUM CHANGES TO THE AIRCRAFT. INCLUDED IN THE STUDY WERE LONG WIRE, EMBEDDED, DIEELECTRI ...

AREAS OF THE OCEAN FLOOR DISPOSED TO MINE BURIAL HAVE SOFT SEDIMENTS (I.E., LOW SHEAR STRENGTH) OR SANDY SEDIMENTS SUBJECT TO SCOUR. KNOWLEDGE OF SEAFLOOR SHEAR STRENGTH, POROSITY, AND GRAIN SIZE WOULD AID THE HUNT FOR BURIED MINES. NORMAL INCIDENCE, ACOUSTIC ECHO SOUNDERS ARE BEING DEVELOPED TO INFER SUCH PHYSICAL PROPERTIES OF THE SEDIMENT. PSI PROPOES TO EVALUATE THE THE POTENTIAL FOR SUCCESS O ...

THERE IS CONSIDERABLE EVIDENCE THAT MINES BURY IN MANY AREAS WHERE BOTH NAVY AND COMMERCIAL SHIPS MUST OPERATE. IF THESE MINES ARE LEFT UNCOUNTERED, THEY POSE A SIGNIFICANT THREAT TO TRANSITING TRAFFIC. FORTUNATELY, NOT ALL SEA BOTTOMS ARE CONDUCIVE TO MINE BURIAL, AND THE BURIED MINE COUNTERMEASURES PROBLEM CAN BE REDUCED BY IDENTIFYING AND APPLYING BURIED MINE COUNTERMEASURES ONLY IN THE AREAS W ...

FIBER OPTIC TECHNOLOGY WHICH HAS BEEN DEVELOPING OVER THE PAST FEW YEARS, OFFERS SIGNIFICANT ADVANTAGES COMPARED TO WIRE DATA LINKS: LOWER LOSS, GREATER BANDWIDTHS, TOLERANCE OF ADVERSE ENVIRONMENTS, AND INSTALLATION FLEXIBILITY. THE INCREASING DATA TRANSMISSION RATES AND DISTRIBUTED PROCESSING ARCHITECTURES OF COMPUTER SYSTEMS REQUIRE HIGH SPEED DATA NETWORKS. MUCH COMPONENT TECHNOLOGY AND COMMER ...

THIS PROPOSAL RESPONDS TO THE NAVY'S NEED FOR NON-PROPRIETARY BONDING SYSTEMS FOR NEOPRENE-TO-METAL VULCANIZED BONDS. THE APPROACH OFFERED IS TO BEGIN WITH THE CHEMLOC 205/220 AND OTHER EXISTING PROPRIETARY AND NON-PROPRIETARY FORMULATIONS, TO ESTABLISH THE EFFECTIVENESS OF CERTAIN MODIFICATIONS THEREOF TO IMPROVE CATHODIC DELAMINATION RESISTANCE. THE MODIFICATIONS PROPOSED INCLUDE ADDITIONSOF REA ...

TO OVERCOME SHORTCOMINGS OF ASW WEAPONRY, NOSC PLANS A TECH BASE PROGRAM IN SUPPORT OF HIGH POTENTIAL ADVANCED ASW WEAPONS CONCEPTS. NUMEROUS CANDIDATES ARE AVAILABLE IN EACH OF THE SIGNIFICANT AREAS OF PROPULSION, WARHEADS, GUIDANCE, QUIETING AND NON-TORPEDO CONCEPTS. THERE IS A NEED FOR A TECHNOLOGY EVALUATION STRATEGY. THE OBJECTIVE OF PHASE I IS TO DEVELOP A STRATEGY THAT ENABLES THE INDIVIDUA ...

CURRENT SHIPBOARD AIRCRAFT SUPPORT EQUIPMENT HAS INADEQUATE CAPABILITY TO RESIST EXPECTED SHOCK LEVELS IN HEAVY WEATHER AND COMBAT OPERATIONS. CAREFUL REVIEW OF THE STATE-OF-THE-ART INDICATES THAT MANY CURRENTLY USED PROCEDURES FOR SHOCK RESPONSE PREDICTION OF SHIPBOARD EQUIPMENT AND FOR SHIP GIRDER RESPONSE TO SHOCK LOADS ARE INADEQUATE BECAUSE OF THE MANY ASSUMPTIONS AND THE OVERSIMPLIFIED MODEL ...

MINE HUNTING WITH SIDE SCAN SONARS AND MAGNETOMETERS IS PROVING TO BE A LOW COST MEANS OF LOCATING MINES AND MINE-LIKE OBJECTS ON THE OCEAN BOTTOM. IT IS ALSO THE MOST EFFECTIVE MEANS OF PRECISELY CHARTING NON-MINE BOTTOM OBJECTS (NOMBOS) THAT CONSITIUE THE CLUTTER IN A CHANNEL OR SEA ROUTE THAT ARE FALSE TARGETS TO MINE HUNTER PLATFORMS. HOWEVER, CURRENT SIDE SCAN SONAR AND MAGNETOMETER SEARCH TE ...
