Acoustech plans a two-year effort aimed at evaluating acoustic dyadic sensors for prospective use in directional sonobuoys utilized by the U. S. Navy. The chief sonobuoys targeted in this study are the AN/SSQ-53 DIFAR, AN/SSQ-77 VLAD, and AN/SSQ-62 DICASSunits. The DIFAR and VLAD buoys are passive devices that have a bandwidth of 5 - 2400 Hz, whereas the DICASS buoy is an active device that has ...

RECENT ADVANCES IN HIGH TEMPERATURE SUPERCONDUCTING (HTSC) THIN FILM TECHNOLOGY ENABLE THE FABRICATION OF LOW-LOSS COMPONENTS THAT WILL IMPROVE THE COST AND PERFORMANCE OF CHANNELIZED RECEIVERS. CHANNELIZED RECEIVERS ARE USED IN SATELLITE TRANSPONDER, ELECTRONIC WARFARE AND ELECTRONICS INTELLIGENCE APPLICATIONS AND ARE COMPRISED OF A GROUP OF NARROW BAND RECEIVERS THAT COVER INDIVIDUAL SLOTS IN A ...

SIGNIFICANT SIMPLIFICATION OF MICROWAVE PHASED ARRAY ANTENNA SYSTEM ARCHITECTURES CAN BE ACHIEVED WITH HTSC DEVICE TECHNOLOGY. ELIMINATION OF THE LOW NOISE AMPLIFIERS (LNAS) CAN BE ACCOMPLISHED THROUGH REPLACEMENT OF THE GAAS PHASE SHIFTERS WITH LOW LOSS HTSC COMPONENTS. A REDUCTION IN COMPLEXITY LOWERS BOTH SYSTEM WEIGHT ANDCOST. KEY TO HTSC TECHNOLOGY INSERTION IN PHASED ARRAY ANTENNAS IS THE DE ...

FERROELECTRICS (FE) HAVE A LARGE COMMERCIAL POTENTIAL AS PIEZOELECTRIC ELEMENTS, DIELECTRICS FOR CAPACITORS, AND IN OPTICAL GUIDED-WAVE DEVICES. MATERIALS PROCESSING HAS LIMITED APPLICATIONS IN MICROELECTRONICS AND PHOTONICS, HOWEVER, AND FEW METHODS ARE CAPABLE OF DEPOSITING HIGH QUALITY THIN FILMS COMPATIBLE WITH STANDARD SI INTEGRATED CIRCUIT PROCESS TECHNOLOGY. METALORGANIC CHEMICAL VAPOR DEPO ...

Long-duration wide-area surveillance missions increasingly are space-based. MEO orbits offer space-based radar systems more time on station, but require very large array apertures on the order of 100m in diameter. Achieving larger apertures with smaller,lighter launch packages and stable on-orbit pointing is a challenge that E-Textiles promises to meet. Textile processes can be used to achieve a l ...

Conventional medium caliber projectiles fall short of desired effectiveness due to factors such as aiming inaccuracy, component manufacturing tolerances, wind effects, etc. A guided projectile that could obviate these factors would substantially improvehit probability, increasing effective range and lethality. Commensurately longer standoff distances also increase warfighter survivability. Furthe ...

THIS PROGRAM'S OBJECTIVE IS TO ESTABLISH THE RELAXOR FERROELECTRIC PB(MG1/2NBS/3)O3 (PMN) AS THE MATERIAL OF CHOICE FOR THIN FILM CAPACITORS IN DRAM AND ELECTRONIC PACKAGING APPLICATIONS.IN CONTRAST TO "NORMAL" FERROELECTRICS, E.G., BATIO3 AND PZT, RELAXORS OFFER HIGH DIELECTRIC CONSTANTS (K>10,000), BROAD PHASE TRANSITIONS,LOW E-FIELD DEPENDENCY OF K, AND LARGE RXC TIME CONSTANTS. IN ADDITION, TH ...
