MECHANICAL BEAM STEERING SYSTEMS ARE LIMITED IN SPEED, COMPACTNESS, RELIABILITY, AND ACCURACY. SIMILAR DIFFICULTIES WERE ENCOUNTERED IN THE DEVELOPMENT OF RADAR SYSTEMS. IN THE CASE OF RADAR, THE DEVELOPMENT OF PHASED ARRAY ANTENNAS ALLOWED GREATER SPEED AND FLEXIBILITY THAN WAS EVER POSSIBLE USING MECHANICALLY STEERED ANTENNAS. ELECTROOPTIC TECHNOLOGIES EXIST WHICH ARE CANDIDATES FOR REPLACING ME ...

THE PROPOSED WORK AIMS TO DEVELOP MULTI-LEVEL OR ANALOG SPATIAL LIGHT MODULATORS (SLMS) THAT INTEGRATE PHOTODETECTORS AND ELECTRONIC INTERAND INTRA-CELL PROCESSING. WE WILL INVESTIGATE A VARIETY OF ANALOG OPTICAL MODULATION EFFECTS IN FERROELECTRIC LIQUID CRYSTALS (FLCS), AND WE WILL DEVELOP APPROPRIATE MULTI-LEVEL ELECTRONIC DRIVING SCHEMES SUITABLE FOR IMPLEMENTATION IN VERY LARGE SCALE INTEGRAT ...

HIGH POWER MICROWAVE (HPM) DIRECTED ENERGY WEAPONS POSE A THREAT TO SYSTEMS WHICH EMPLOY ADVANCED INTEGRATED CIRCUITS (VLSI/VHSIC). THESE CIRCUITS, WHICH USE SMALL GEOMETRY DEVICES, ARE SUSCEPTIBLE TO UPSET AND DAMAGE DUE TO THE LARGE CURRENTS AND VOLTAGES WHICH COUPLE TO THE PRINTED CIRCUIT BOARDS FROM HPM SOURCES. ELECTROSTATIC DISCHARGE PROTECTION IS INADEQUATE FOR THE REPETITIVE PULSE NATURE O ...

AN INNOVATIVE CONCEPT FOR A NEW CLASS OF EMP SIMULATORS IS PROPOSED. THE ELECTROMAGNETIC EQUIVALENCE PRINCIPLE IS APPLIED TO PROVIDE A THREAT LEVEL SIMULATION WITH A BANDWIDTH GOAL OF 1 GHZ AND ARBITRARY ANGLES OF INCIDENCE AND POLARIZATION ARE PROVIDED BY SOFTWARE. IT IS ENVIRONMENTALLY SOUND AND IS HIGHLY AUTOMATED. IT IS EXPECTED TO BE LESS EXPENSIVE TO PROCURE AND MAINTAIN THAN CONVENTIONAL ME ...

THIS PROPOSAL CONSISTS OF USING A LOW COST FORMABLE MANDREL MATERIAL WHICH IS CAPABLE OF EASY REMOVAL THROUGH SMALL OPENINGS. THESE MANDRELS CAN BE PURCHASED IN DIFFERENT ALLOY FORMS TAILORED TO WITHSTAND THE REQUIRED CURE TEMPERATURES AND PRESSURES ASSOCIATED WITH GRAPHITE/EPOXY AND GRAPHITE/THERMOPLASTIC COMPOSITE FABRICATION. THIS PROPRIETARY MATERIAL (STANDARD COMMERCIAL ITEM) HAS A COEFFICIEN ...

THE DEVELOPMENT OF SIMULATION MODELS OF A DISTRIBUTED SYSTEMS AND THEIR MAPPING INTO A PARALLEL SYSTEM, IS A HIGHLY COMPLEX TECHNICAL TASK BECAUSE OF THE GREAT INFLUENCE ITS VARIOUS ELEMENTS WILL HAVE ON ITS PERFORMANCE. THERE ARE MAJOR TECHNICAL ISSUES INVOLVED IN PERFORMING SUCH COMPLEX SIMULATION EFFORT, INCLUDING UNIQUE REQUIREMENTS SIMULATION MODELS, VARIED ARCHITECTURAL CONCEPTS OF DISTRIBUT ...

THIS PROPOSAL DESCRIBES AN INNOVATIVE FILTERING TECHNIQUE THAT CAN BE USED TO DETECT AND REJECT OUT-OF-TOLERANCE MEASUREMENTS FROM A DIFFERENTIAL GPS NAVIGATION SOLUTION. THE TECHNIQUE CAN BE APPLIED FOR BOTH MOBILE AND STATIC APPLICATIONS AND COULD BE INTEGRATED INTO SHIPBOARD OR REFERENCE STATION GPS RECEIVERS. USING THE FILTER DESIGN PROPOSED, ERRORS CAUSED BY MULTIPATH, SATELLITE, RECEIVER ORR ...

GPS IS PLANNED TO BE USED BY THE U.S. ARMY IN A VARIETY OF TACTICAL SCENARIOS. FIRE CONTROL APPLICATIONS ARE CURRENTLY BEING INVESTIGATED WHERE GPS WOULD BE USED TO TRACK REGISTRATION ROUNDS AND LOCATE RADIOSONDES. SINCE GPS IS A RADIONAVIGATION SYSTEM, ITS EFFECTIVENESS IN A TACTICAL ENVIRONMENT IS LIMITED BY ITS SUSCEPTIBILITY TO ELECTRONIC COUNTERMEASURES (ECM). IT IS PARTICULARLY DIFFICULT TO ...

N/A

A PORTABLE, LOW COST FM-CW DOPPLER WEATHER RADAR IS PROPOSED TO PROVIDE "REAL-TIME" METEOROLOGICAL DATA IN THE FIELD. SUCH A SYSTEM WOULD ASSIST BATTLEFIELD DECISION MAKING BY MONITORING CONDITIONS PERTINENT TO MICROWAVE DUCTING, ARTILLERY CONTROL, AND DETERMINING LOCAL WEATHER. CURRENT DOPPLER WEATHER RADARS TEND TO BE PULSED, VERY LARGE, AND TO COST MILLIONS OF DOLLARS; THEY REQUIRE A LARGE OPER ...
