THE PROPOSED PHASE I EFFORT CONSISTS OF ANALYSIS AND EVALUATION OF TECHNIQUES FOR MEASUREMENT OF ACOUSTIC SENSOR POSITIONS IN LONG TOWEDARRAYS FOR USE IN REDUCING PERFORMANCE DEGRADATIONS DUE TO ARRAY MOTIONS AND DISTORTION. PRESENT AND FUTURE ARRAY DESIGNS AND OPERATING ENVIRONMENTS WILL BE CONSIDERED, WITH SPECIFIC ATTENTION TO NONACOUSTIC SENSOR SUITES AND CAPABILITIES. A SURVEY OF SHAPE ESTIMA ...

AN ADAPTIVE ARRAY SIGNAL PROCESSOR CAPABLE OF ADAPTIVELY NULLING MULTIPE SIDELOBE JAMMERS AND SIDELOBE DISTRIBUTED AND DISCRETE GROUND CLUTTER RETURNES COMPETING WITH THE TARGET RETURN, IN AI-LOW OBSERVABLE TARGET DETECTING MEDIUM-PRF RADARS IS THE SUBJECT OF A DESIGN STUDY. THE ASI-DEVELOPED AIRBORNE RADAR ADAPTIVE ARRAY SIMULATION TEST BED (IMPLEMENTED IN A PC-286 COMPUTER) IS PROPOSED TO BE USE ...

LONG WAVELENGTH GROUND-BASED MULTISTATIC RADAR SYSTEMS WHICH MAY BE IN THE HF, VHF, OR UHF BANDS OFFER POTENTIAL SOLUTIONS TO THE PROBLEMS ASSOCIATED WITH PERFORMING THE TACTICAL ARMY MISSION OF FOREWARD AREA AIR DEFENSE (FAAD) AND WEAPONS LOCATION WITH MONOSTATIC SHORT WAVELENGTH RADARS. HOWEVER, SIGNIFICANT PROBLEMS ARE ALSO INTRODUCED WITH THE USE OF THESE LONG WAVELENGTH BISTATIC RADAR SYSTEMS ...

MISSILE SEEKERS MUST DETECT TARGETS IN DUAL BANDS (3-5 UM AND 8-12 UM). THEY NOW USE HYBRID ASSEMBLY OF TWO SEPARATE ARRAYS, WHICH INCREASES THE POWER, CONSUMPTION, THE WEIGHT, AND THE COST. WE WILL DEVELOP MONOLITIHIC DUAL BAND 128X128 STARING ARRAYS ON HGCDTE MATERIAL. THE INNOVATION IS THE DETECTION OF BOTH LONG AND SHORT WAVE SIGNALS IN THE SAME PIXEL SIMULTANEOUSLY. FABRICATION METHODS ARE DE ...

MODERN COMPUTER TECHNOLOGY OFFERS THE CAPABILITY TO PERFORM REAL-TIME PROCESSING OF MATHEMATICAL MODELS FAR MORE SOPHISTICATED THAN THOSE CURRENTLY BEING UTILIZED IN TRAINING APPLICATIONS. THE CAPABILITY TO COST EFFECTIVELY IMPLEMENT BLADE ELEMENT ROTOR MODELS IN REAL TIME USING MULTIPROCESSOR ARCHITECTURES AND RISC TECHNOLOGY PROCESSORS HAS BEEN DEMONSTRATED. IN ORDER TO EFFECTIVELY UTILIZE THIS ...

SINGLE ROTOR HELICOPTERS HAVE OFTEN ENCOUNTERED AN UNANTICIPATED RIGHT YAW (URY). THIS OCCURS PREDOMINANTLY AT LOW SPEED IN GROUND EFFECT WITH THE RELATIVE WIND FROM THE LEFT OR REAR. THIS APPEARS TO BE CAUSED BY AERODYNAMIC INTERFERENCE PHENOMENA THAT CAN ONLY BE ANALYTICALLY MODELED BY A FREE VORTEX WAKE MODEL WITH GROUND EFFECT. ART HAS DEVELOPED SUCH A MODEL AND WILL INCORPORATE IT IN FLIGHTLA ...

AGILIS CORPORATION PROPOSES TO DEVELOP THE SYSTEM CONCEPT FOR A MODULAR SOLDIER'S COMPUTER. THIS EFFORT IS A DIRECT EXTENSION OF AGILIS' ONGOING WORK WITH COMMERCIAL CLIENTS TO DEVELOP SIMILAR CAPABILITIES. THE MODULAR SOLIDER'S COMPUTER MUST BE VERY SMALL (POCKET-SIZED), LIGHT WEIGHT (1 TO 2 POUNDS), RUGGED, POWERFUL, NETWORKED, AND HAVE AN ADVANCED USER INTERFACE. MILITARY APPLICATIONS INCLUDE B ...

THE EMERGENCE OF VLSI TECHNOLOGY HAS INCREASED THE COMPLEXITY OF INTEGRATED CIRCUIT DEVICES, IN TERMS OF TRANSISTORS PER DEVICE, AT A RATE MULTIPLYING BY 100 EVERY 10 YEARS. NEW TECHNOLOGIES, SUCH AS SURFACE MOUNT, REQUIRE SPECIAL TECHNIQUES TO MAKE THE BOARDS TESTABLE. THE GOAL OF THIS RESEARCH AND DEVELOPMENT PROJECT IS TO REVIEW RELATED RESEARCH AND DEVISE VARIOUS WAYS TO SEMIAUTOMATICALLY ADD ...

THIS PROPOSAL RESPONDS TO THE TECHNICAL NEEDS OF INTEGRATED ESTIMATION, GUIDANCE AND CONTROL SYSTEMS FOR ADVANCED BANK-TO-TURN (BTT) MISSILE APPLICATIONS. FOUR TECHNICAL INNOVATIONS ARE ANTICIPATED: (L) AN ADAPTIVE MULTIMODE SENSOR DATA FUSION RULE WHICH OPTIMIZES ACQUISITONS BY ACCOUNTING FOR INDIVIDUAL SENSOR'S CHARACTERISTICS AND THE VARYING ENVIRONMENT CONDITIONS; (2) A MANEUVERING TARGET TRAC ...

BACKLIGHTS FOR PORTABLE COLOR LCD MATRIX DISPLAYS ARE EXTREMELY INEFFICIENT: 96% OF THE BATTERY POWER IS WASTED ON THE BACKLIGHT SYSTEM. A HIGH EFFICIENCY BACKLIGHT SYSTEM IS PROPOSED BASED ON THE USE OF MICRO-OPTICAL IMAGING OF RGB PHOSPHOR TRIADS ONTO THE LCD RGB PIXEL ROWS SO THAT THE 67% LOSS IN THE LCD FILTER SYSTEM IS AVOIDED. IN ADDITION A SPECIAL COLLIMATOR IS PROPOSED THAT CONCENTRATES TH ...
