1Innovative techniques for radar high angle resolution are proposed for investigation in a Phase I effort to enable the resolution of the direction of arrival (DOA) of returns from multiple targets that fall within one beamwidth and within the same range and Doppler Cells. The techniques proposed emphasize the pursuit for optimal utilization of available aperture space, by a combination of arrange ...

HYPERSONIC AND SUPERSONIC SPEEDS ARE FEASIBLE DUE TO ADVANCES IN AEROSPACE ENGINEERING, VEHICLE DESIGN, AND PROPULSION TECHNOLOGY. THE EFFICIENCIES, RELIABILITY, AND ULTIMATE POTENTIAL OF AIR BREATHING PROPULSION SYSTEMS HINGE UPON NEW MATERIALS THAT CAN SURVIVE THE HARSH COMBUSTION ENVIRONMENTS. HAFNIUM AND ZIRCONIUM CARBIDE AND BORIDE MATRICES ARE CANDIDATE MATERIALS SYSTEMS, BUT ONLY IF MANUFAC ...

MANY INFRARED AND ELECTRO-OPTICAL IMAGING SYSTEMS ARE CONFOUNDED BY FOG AND DUST. MILLIMETER EAVE IMAGING SYSTEMS WOULD NOT BE AFFECTED BY THESE BATTLEFIELD OBSCURANTS. HOWEVER, THE LIQUID HELIUM COOLING REQUIREMENT OF TODAYS HIGH PERFORMANCE LOW NOISE MIXERS IS BLOCKING THE DEPLOYMENT OF ADVANCED MILLIMETER WAVE COMMUNICATIONS AND IMAGING SYSTEMS. IN PRINCIPAL, JOSEPHSON MIXERS FABRICATED WITH TH ...

ADVANCED COMPOSITES LABORATORIES WILL DEVELOP AN IMPROVED MOUNTAINEERING SKI FOR MILITARY USE. WE WILL INCORPORATE THE BEST OF DOWNHILL SKI TECHNOLOGY WITH THE BEST OF TELE MARK AND MOUNTAINEERING SKI TECHNOLOGY TO PRODUCE A SKI FOR THE US MARINE CORPS WHICH WILL MEET THE REQUIREMENTS OF THE MARINE CORPS TOICS N86-13. WE WILL USE ADVANCED COMPOSITE MATERIALS TO ALLOW US TO PROVIDE A HIGH PERFORMAN ...

THE OBJECTIVE OF THE PROPOSED PROJECT IS TO EVALUATE THE FEASIBILITY OF AN ON-LINE MONITOR OF OIL CONDITION WHICH WOULD DETECT THE PRESENCE AND NATURE OF DEBRIS PARTICLES IN LUBRICATING OIL SYSTEMS. THIS WOULD PROVIDE A MORE TIMELY AND LESS LABOR INTENSIVE METHOD OF OIL CONDITION MONITORING THAN PRESENT METHODS THAT INVOLVE OFF-LINE ANALYSIS. THE PROPOSED APPROACH WOULD CONSIST OF MEASURING THE FO ...

change induced in the wavelength of ruby R-line fluorescence. Timehe resolution will be 0.1 microsecond. Axi innovative detector of this wavelength shift avoids the need for a dispersive optical system and streak camera, as previously used. The fluorescence will be excited by an argon ion laser. materials having less temperature sensitivity than ruby, and the use of non-laser excitation sources.

ALPHATECH'S ITERATIVE MODELING METHODOLOGY (AIMM) DEVELOPS A SYSTEM REPRESENTATION BY USING A TEAM-BASED APPROACH TO DEVELOPING A SERIES OF CHART-BASED MODELS OF THE SYSTEM WITHIN THE CONTEXT OF AN APPROPRIATE SCENARIO; THIS SET OF CHART-BASED MODELS CULMINATES WITH A PETRI NET REPRESENTATION WHICH CAN BE DIRECTLY IMPLEMENTED IN ALPHATECH'S SIMULATION TOOL, MODELER. THE COMPUTER MODEL THAT RESULTS ...

THE OBJECTIVE OF THIS RESEARCH IS TO DETERMINE THE FEASIBILITY OF USING THE STOCHASTIC, TIMED, ATTRIBUTED PETRI NET (STAPN) METHODOLOGY TO DESCRIBE AND ANALYZE ALTERNATIVE NAVAL C3 ARCHITECTURES. THE US NAVY IS IN THE PROCESS OF DEVELOPING C3 ARCHITECTURES TO SUPPORT THE NAVY'S MISSION AND FUNDAMENTAL WARFARE TASKS. THIS PROCESS INVOLVES ASSESSING ALTERNATIVE C3 ARCHITECTURES TO DETERMINE THEIR IM ...
