A PROTOTYPE GUIDANCE AND CONTROL SYSTEM SENSOR FOR DIRECTED ENERGY WEAPONS IS PROPOSED. THIS GUIDANCE SUBSYSTEM SENSOR WILL USE THE GLOBAL POSITIONING SYSTEM (GPS) SATELLITE CONSTELLATION FOR BOTH POSITION AND ATTITUDE DETERMINATION OF THE DEW. THIS GPS ATTITUDE DETERMINATION SYSTEM CAN BE CAN BE APPLIED FOR POINTING AND ATTITUDE CONTROL OF MANY TYPES OF DEWS, INCLUDING GROUND, AIR, AND SPACE BASE ...

DMS (DILUTED MAGNETIC SEMICONDUCTOR) CRYSTAL WILL MEASURE MAGNETIC FIELD STRENGTHS OF A HYPERVELOCITY GUN (HVG), WITH UNIQUELY HIGH DIRECTIVITY AND SPATIAL RESOLUTION, UNDER A HARSH ELECTRO-MAGNETIC INTERFERENCE (EMI) CONDITION. KNOWLEDGE OF THE MAGNETIC FIELD STRUCTURE BEHIND AND AHEAD OF A PROJECTILE IS ESSENTIAL FOR DESIGNING AN EFFICIENT HVG OF SDI INTEREST, ALTHOUGH EMI MAKES SUCH A MEASUREME ...

IN RADAR, LIDAR, SONAR, AND ULTRASOUND SYSTEMS, RANGE RESOLUTION CAN BE IMPROVED BY INCREASING SIGNAL BANDWIDTH, BUT AZIMUTH (CROSS-RANGE) RESOLUTION IS LIMITED BY ARRAY OR APERTURE SIZE. THE SPACE-TIME TRANSMISSION PATTERN IS TYPICALLY MUCH NARROWER IN RANGE THAN IN AZIMUTH, YIELDING A LINE-LIKE FUNCTION THAT SAMPLES ENVIRONMENTAL REFLECTIVITY AS THE SYSTEM SCANS ITS SURROUNDINGS. OVEMENT OF TRAN ...

OPTIMUM MULTISENSOR PROCESSING IS ACCOMPLISHED BY FORMING A LARGE, DISTRIBUTED SENSOR ARRAY COMPOSED OF SUBARRAYS THAT MAY BE SEPARATED BY LARGE DISTANCES. ACQUISITION IS ACCOMPLISHED BY IMPLEMENTING A HYPOTHESIS TEST FOR AN OBJECT IN EACH VOLUME ELEMENT OF THE SPACE TO BE SEARCHED. SUCH TESTS PRODUCE LIKELIHOOD STATISTICS THAT CAN BE USED FOR DETECTION AND POSITION/VELOCITY ESTIMATION. THE SIZE A ...

MODERN APPLICATIONS OF ACCELERATORS DEMAND RUGGED AND EFFICIENT PHOTOCATHODE SOURCES. WE ARE IMPROVING THE QUANTUM EFFICIENCY OF RUGGED PHOTOCATHODE MATERIALS USING SURFACE PLASMON EXCITATION. OUR SCHEME USES TWO LIGHT BEAMS, ONE TO EXCITE THE SURFACE PLASMONS ON A MODIFIED SURFACE OF THE MATERIAL AND ONE TO CREATE EXCITED ELECTRONS WHOSE PROBABILITY OF ESCAPING IS ENHANCED 10-30 TIMES BY THE PRES ...

THERE IS A CONSIDERABLE NEED FOR HIGH POWER JITTER-FREE SWITCHING IN THE SDIO INDUCTION ACCELERATOR PROGRAM. THE HIGH POWER SWITCHES CURRENTLY AVAILABLE ARE MAINLY BASED ON AN ELECTRICAL DISCHARGE IN GAS OR VACUUM, AND THEREFORE HAVE CERTAIN LIMITATIONS IN PULSE RISETIME, REPETITION RATE, TEMPORAL JITTER, RELIABILITY, LIFETIME RECOVERY, SWITCH SIZE, AND SWITCH WEIGHT. AN ALTERNATIVE HIGH POWER SWI ...

THE NEXT GENERATION SPACECRAFT WILL BE MADE OF NEW STRONG, LIGHTWEIGHT MATERIALS WITH LITTLE DAMPING SO THAT ACTIVE VIBRATION SUPPRESSION IS ESSENTIAL. THESE SPACECRAFT, FUNCTIONING IN A REMOTE HOSTILE ENVIRONMENT WHERE IMMEDIATE REPAIR IS PRECLUDED, MAY SUSTAIN DAMAGE FROM EXTERNAL DISTURBANCES AND AGING. TO ADDRESS THE OPERATIONAL REQUIREMENTS OF FUTURE SPACECRAFT, THIS PROGRAM IS DEVELOPING AN ...

A SAFE AND CRITICAL COMPUTING POLICY IS PROPOSED. IT CONSIDERED THE EXISTING GOVERNMENT GUIDELINES FOR SAFETY AND CRITICALITY AND FOR INFORMATION SECURITY. THE POLICY INCLUDED CONFIDENTIALITY (SECRECY), INTEGRITY AND ASSURED SERVICES (FAULT TOLERANCE). SAFE AND CRITICAL COMPUTER TECHNOLOGY IS BEING DEVELOPED BY THE INTEGRATION AND ENHANCEMENT OF THE FOLLOWING DISCIPLINES: 1. FAULT TOLERANCE AGAINS ...

ASPECC MAKES USE OF THE EXPONENTIALLY LARGE INCREASE IN SURFACE AREA WHICH ACCOMPANIES A FRACTIONATED SPECIFIC VOLUME. THOUGH THE MATH INDICATES VOLTAGES AS HIGH AS 10E9 AT 10E6 JOULES FOR SOME OF THE EXAMPLES DESCRIBED HEREIN, PHASE I AND II OF THIS PROJECT WILL ONLY PURSUE THE TESTING OF AN ASPECC AT 100 TO 300 VOLTS DUE TO TECHNICAL LIMITS OF PRESENTLY AVAILABLE MATERIALS. SINCE ELECTRIC CHARGE ...
