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 ...

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 ...

APPLIED MODERN TECHNOLOGIES CORPORATION (AMTECH) HAS DEVELOPED A METHOD BY WHICH THE EYES OF PERSON USING A HMD CAN BE TRACKED IN ANGULAR DISPLACEMENT AND CHARACTERIZED AS TO THE VISUAL ACCOMMODATION WITH A SINGLE OPTICAL SYSTEM (FOR EACH EYE). AMTECH PROPOSES HEREIN TO BUILD A BREADBOARD, HELMET-MOUNTED OPTOMETER FOR LABORATORY PROOF-OF-CONCEPT DEMONSTRATION. THE DEMONSTRATION SYSTEM WILL BE CONF ...

THE OBJECTIVE OF THE PROGRAM IS TO DESIGN RAKE PROBES THAT CAN ACCURATELY MEASURE AND MAP ARC-JET EXIST PLANE FLOW QUANTITIES. THREE RAKE PROBES SHALL BE DESIGNED THAT CAN MAP OUT THE AERODYNAMIC PROPERTIES OF THE TEST SECTION IN HIGH-ENTHALPY/HIGHPRESSURE ARC-JETS. THE FIRST PROBE SHALL BE A CYLINDRICAL PRESSURE/CALORIMETER RAKE THAT CAN BE SWEPT ACROSS THE TEST SECTION TO MEASURE PRESSURE, CONVE ...

FIBER OPTIC SENSORS HAVE BEEN DEVELOPED FOR A VARIETY OF INDUSTRY MONITORING AND CONTROL APPLICATIONS. FULLY REALIZATION OF THE POTENTIAL CAPABILITY OF THE FIBER OPTIC INTENSITY SENSORS, HOWEVER, REQUIRE INNOVATIVE APPROACHES TO PRACTICAL IMPLEMENTING METHODS TO MULTIPLEXING THE INTESITY SENSORS INTO FIBER OPTIC DATA NETWORKS. A NOVEL WAVELENGTH DIVISION MULTIPLEXING TECHNIQUE ON A UNIQUE DEVICE, ...

AN INNOVATIVE AND COST-EFFECTIVE APPROACH IS PRESENTED FOR DEVELOPMENT OF EXPLOSIVE SAFETY (QUANTITY-DISTANCE) CRITERIA FOR SHALLOW TUNNELS. THE APPROACH PROPOSES TO FORMULATE AND VALIDATE THE SCALING LAWS FOR Q-D INCORPORATING PROPERTIES OF EXPLOSIVES, AS WELL AS THE PHYSICAL AND MECHANICAL CHARACTERISTICS OF ENGINEERING SYSTEMS, I.E. CONCRETE, STEEL REINFORCING ELEMENTS, ETC.; AND GEOLOGIC SYSTE ...

THE DISCOVERY OF A MULTITUDE OF SUPERCONDUCTING OXIDE MATERIALS HAS OPENED UP NEW POSSIBILITIES FOR DEVELOPING INFRARED DETECTORS. THERE HAS ALREADY BEEN A CONSIDERABLE AMOUNT OF EFFORT EXPENDED ON STUDYING THE DETECTION PROPERTIES OF YBA2CU3O7 (YBCO)FILMS. THE BEST RESULTS ON YBCO HAVE COME FROM STUDIES ON BALOMETERS. HOWEVER, SOME OF THE MOST INTRIGUING RESULTS OBTAINED FROM SUPERCONDUCTING THIN ...

WE PROPOSE TO DEVELOP A SENSING TECHNIQUE BASED UPON LASER EXCITED FLUORESCENCE FROM MOLECULAR OXYGEN IN AIR WHICH CAN BE USED FOR ENGINE INLET FLOW FIELD ANALYSIS IN SUPPORT OF HYPERSONIC PROPULSION SYSTEM DEVELOPMENT AT AEDC. THE APPROACH PROPOSED IS CAPABLE OF PROVIDING ACCURATE SINGLE PULSE DETERMINATIONS OF FLOW TEMPERATURE AND DENSITY. THIS APPROACH IS BASED UPON PULSED LASER EXCITATION OF T ...

SCANNING PROBE MICROSCOPES HAVE BECOME COMMON INSTRUMENTS FOR THE IMAGING OF SURFACE FEATURES WITH VERY HIGH RESOLUTION. THE FUNDAMENTAL CHARACTERISTICS OF SCANNING PROBE MICROSCOPES INCLUDE THE CAPABILITY TO POSITION A VERY SHARP PROBE WITH ULTRA-HIGH RESOLUTION IN THREE DIMENSIONS. THIS CAPABILITY HAS STIMULATED INTEREST IN EXTENDING SCANNING PROBE TECHNOLOGY TO THE CONSTRUCTION OF VERY SMALL ST ...
