THE PROBLEM OF RELIABLY DETECTING AND CORRECTLY CLASSIFYING MOBILE TARGETS IS AN UNSOLVED PROBLEM OF GREAT MILITARY SIGNIFICANCE. IN THIS PROJECT, HNC WILL APPLY ITS NEW MULTIFUSION APPROACH TO MULTIPLE SENSOR FUSION AND A PRIORI KNOWLEDGE EXPLOITATION TO THE PROBLEM OF MOBILE TARGET DETECTION. THE MULTIFUSION APPROACH UTILIZES NEURAL NETWORKS TO CARRY OUT PRE-CLASSIFICATION FEATURE EXTRACTION AND ...

CURRENT METHODS FOR PREDICTING THE EFFECTS OF WIND ON PROJECTILE TRAJECTORIES ARE LIMITED, BECAUSE THESE METHODS ASSUME A HOMOGENEOUS WIND VECTOR. ACTUAL WIND PATTERNS ARE INHOMOGENEOUS IN TERMS OF BOTH DIRECTION AND RANGE. TO SOLVE THESE PROBLEMS, PHYSICAL OPTICS CORPORATION (POC) PROPOSES A NOVEL LDV DESIGN, BASED ON A COMBINATION OF POC'S UNIQUE MULTIPLEXED HOLOGRAPHIC OPTICAL ELEMENTS (HOES) A ...

A NEW TYPE OF RANGE EXTENT SIMULATOR HAS BEEN MADE POSSIBLE THROUGH RECENT DEVELOPMENTS IN THE EMERGING MICROELECTRONIC TECHNOLOGY OF ACOUSTIC CHARGE TRANSPORT (ACT). THIS TECHNOLOGY, DEVELOPED JOINTLY BY DARPA AND THE U.S. AIR FORCE, HAS ENABLED THE IMPLEMENTATION OF DIGITALLY PROGRAMMABLE ANALOG MULTITAP DELAY LINES. USED AS A PROGRAMMABLE RANGE EXTENT DEVICE, THE ACT DEVICE PROVIDES HUNDREDS OF ...

KNOWLEDGE INDUSTRIES WILL EXPLORE PROBLEMS WITH REAL-TIME SENSOR MANAGEMENT, WITH A FOCUS ON FORMAL PROBABILISTIC AND DECISION-THEORETIC METHODS FOR REASONING UNDER UNCERTAINTY. FROM THE PERSPECTIVE OF DECISION ANALYSIS, WE VIEW SENSOR MANAGEMENT AS INCLUDING TWO KEY COMPONENTS: (1) ASSIGNMENT OF PROBABILITIES TO COMPETING EXPLANATIONS, GIVEN CURRENT SENSOR DATA; AND (2) DETERMINING WHICH SENSOR, ...

A 90 DEGREE PHASE SHIFTER CAPABLE OF CONTINUOUS OPERATION AT 4-8 GHZ, 80K AND POWER LEVELS OF 1-5 WATTS WILL BE DOMONSTRATED IN PHASE I. WEPROPOSE TO DEVELOP THE PHASE SHIFTER USING HIGH TEMPERATURE SUPERCONDUCTING THALLIUM THIN FILMS AND DEMOSTRATE THE POWER HANDLING CAPABILITY OF THE DEVICE. THE REDUCED SIZE AND POWER DISSIPATION OF THESE DEVICES HAVE ADVANTAGES FOR SYSTEMS APPLICATIONS WHERE VO ...

REALISTIC GROUND VIBRATION TESTING OF FLEXIBLE SPACECRAFT REQUIRES A MEANS FOR SUPPORTING THE TEST ARTICLE IN 1-G WITHOUT IMPOSING CONSTRAINT FORCES DUE TO STIFFNESS, MASS, DAMPING, OR FRICTION. SPACECRAFT HAVING LARGE, FLEXIBLE APPENDAGES WITH HIGH AREA/MASS RATIOS ARE PARTICULARLY DIFFICULT BECAUSE AIR EFFECTS REQUIRE THAT THEY BE TESTED IN A VACUUM. THE PROPOSED DEVELOPMENT WILL ATTEMPT TO ENHA ...

THE AIR FORCE HAS BEEN USING COMPUTER-BASED TRAINING FOR MORE THAN 20 YEARS, YET IT STILL CONFRONTS MANY OF THE SAME BASIC PROBLEMS: SUBJECT MATTER EXPERTS ARE USUALLY NOT INSTRUCTIONAL DESIGNERS, INSTRUCTIONAL DESIGNERS ARE USUALLY NOT PROGRAMMERS, CBT COURSEWARE IS EXPENSIVE TO DEVELOP (TYPICALLY 400 HOURS PER HOUR OF DELIVERABLE TRAINING), AND COURSEWARE DESIGN IS RARELY SUPPORTED BY VALIDATED ...

RESERVE BATTERIES WITH IMPROVED ENERGY DENSITY AND VOLTAGE REGULATION ARE NEEDED WHICH ARE CAPABLE OF MEETING EXISTING AND FUTURE STRATEGIC MISSILE REQUIREMENTS. SILVER OXIDE CATHODES WITH SUPERIOR THERMAL STABILITY (AGING) AND VOLTAGE PERFORMANCE WILL BE EVALUATED USING NEW, UNUSUALLY EFFICIENT ELECTRODE STRUCTURES. AN INNOVATIVE HYBRID CELL CONSTRUCTION, LIGHTWEIGHT CURRENT COLLECTORS, AND NEW L ...

Associate systems, as complex integrated human-machine systems, pose difficult problems for verification and validation testing. Traditional emphases on analysis or statistical hypothesis testing are not powerful enough to effectively test such systems. The most promising approaches to verificaton and validation testing or associate systems are descriptive methods using interpretive analysis. Thes ...

BECAUSE OF THEIR UNIQUE ELECTRONIC PROPERTIES, DIAMOND THIN FILMS OFFER AN OPPORTUNITY TO GREATLY IMPROVE THE EFFICIENCY OF MICROWAVE POWER TUBE SYSTEMS BY USING A HIGH EFFICIENCY COLD CATHODE EMPLOYING DIAMOND NEGATIVE ELECTRON AFFINITY COATINGS TO ACHIEVE LOW WORK FUNCTION AND LOW EMITTER RESISTANCE^ IN ADDITION, BECAUSE OF DIAMOND'S THERMAL SHOCK RESISTANCE AND RESISTANCE TO RADIATION AND CHEMI ...
