Future synthetic aperture interferometric radiometers, such as JPL's New Millenium Program, Geostationary Synthetic Aperture Microwave Sounder (GEO/SAMS) instrument, will employ a thinned array of hundreds of miniaturized receivers and a massively parallel cross-correlator system for digital signal processing. The objectives of Phase I are to develop, fabricate, and test a proof-of-design of a 64- ...

CURRENT SPACECRAFT DATA HANDLING SYSTEMS USING TIME DIVISIONMULTIPLEXED (TDM) TECHNIQUES ARE FREQUENTLY MISSION-UNIQUE DESIGNS. USE OF DATA PACKETS PROVIDE SEVERAL BENEFITS INCLUDING IMPROVED GROUND DATA PROCESSING. INCORPORATION OFDATA TRANSPARENCY CAN ALSO ENHANCE UTILIZATION OF GROUND EQUIPMENT FOR MULTIPLE MISSION PHASES. THE INCREASED SOPHISTICATION OF SPACECRAFT INSTRUMENTS, AND REQUIREMENTS ...

THE PERFORMANCE OF IMAGING SYSTEMS IS HIGHLY DEPENDENT ON THE INTENSITY AND DISTRIBUTION OF LIGHT ILLUMINATING THE SCENE. THE HUMAN VISUAL SYSTEM PERFORMS WELL OVER A RANGE OF SCENE BRIGHTNESS FAR GREATER THAN THAT WHICH MAN-MADE IMAGE SENSING SYSTEMS ARE CAPABLE OF OPERATING. ODETICS, INC. PROPOSES AN OPTICAL MODEL WHICH: GREATLY INCREASES THERANGE AND VARIABILITY OF SCENE ILLUMINATION; VASTLY IM ...

IT IS PROPOSED TO EXPLORE THE FEASIBILITY OF ADDING ADAPTIVE AND STOCHASTIC FEATURES TO A CONTENT-ADDRESSABLE MEMORY (CAM) IN SUCH A MANNER THAT THE DEVICE BECOMES CAPABLE OF LEARNING FROM INSTRUCTION AND EXPERIENCE. THE ALGORITHM OF THE ADAPTIVE STOCHASTIC CONTENTADDRESSABLE MEMORY (ASCAM) IS THE SAME AS THAT OF ADAPTIVE NEURAL NETWORKS, VIZ., ITERATIVE THRESHOLDED MATRIX-BINARY VECTOR MULTIPLICA ...

IF A PRACTICAL DIRECT CALORIMETER SYSTEM WERE AVAILABLE FOR THE MEASUREMENT OF METABOLIC HEAT RELEASES IN ANIMALS IN ORBITAL LABORATORIES, IT WOULD BE POSSIBLE TO QUANTIFY SUCH PROCESSES AS 1) CHANGES IN BONE MINERAL AND MUSCLE STATUS (AS A RESULT OF WEIGHTLESSNESS) AND 2) CHANGES IN THE IMMUNESYSTEM (AS A RESULT OF STRESS AND RADIATION FORCE FIELDS) INTERMS OF THE CORRESPONDING METABOLIC CHANGES. ...

LOCAL MEMORY, PARALLEL PROCESSING COMPUTER SYSTEMS OFFER THE POTENTIAL TO REALIZE PREVIOUSLY UNAVAILABLE LEVELS OF PERFORMANCE AT COSTS FAR LOWER THAN CURRENT UNIPROCESSOR TECHNOLOGY PERMITS. HOWEVER, THE ARCHITECTURES OF THESE PARALLEL SYSTEMS PRESENT DIFFICULT PROBLEMS FOR BOTH DATA ACCESS AND DATA COMMUNICATIONS. THE ARACHNID SYSTEM IS PROPOSED AS A GENERAL SOLUTION TO THESE PROBLEMS. ARACHNID ...

This proposed program will result in the developmentof the next generation of millimeter and submillimeter wave, tunable Backward Wave Oscillators (BWOs). Successful development will result in devices that require significantly less input power, require less cooling, have reduced weight, and improved mode purity than current devices. Calabazas Creek Research, Inc. (CCR) is proposing to develop the ...

BARNACLE REMOVAL ON SHIPS ENTAILS SIGNIFICANT COST TO THE NAVY, AND CURRENT ANTI-FOULING PAINTS ENTAIL ENVIRONMENTAL PROBLEMS. FLUOROCHEM HAS DEVELOPED A FLUORINATED POLYURETHANE WITH BARNACLE-RESISTANT PROPERTIES. IN THE PROPOSED PROGRAM, RELATED POLYMERS CONTAINING DISILOXANE SEGMENTS WILL BE PREPARED TO INCREASE CHAIN FLEXIBILITY AND PROVIDE IMPROVED LOW-TEMPERATURE PROPERTIES. ANTICIPATED BENE ...

DEVELOPMENT OF AN ADVANCED MONOLITHIC GAAS 8.5 VOLTAGE CONTROLLED OSCILLATOR WITH ON-CHIP GENERATION OF A LOW FREQUENCY REFERENCE OUTPUT, SUITABLE FOR PHASE LOCKED LOOP APPLICATIONS, IS PROPOSED. CIRCUIT ELEMENTS AND DESIGNS TECHNIQUES TRADITIONALLY RESERVED FOR MICROWAVE APPLICATIONSARE UTILIZED TO OBTAIN THE HIGH SPEED DIVIDE BY N CIRCUIT. A COHERENT REFERENCE SIGNAL IN THE 90-200 MHZ RANGE IS T ...

THE GOAL OF THIS PROJECT IS AN INNOVATIVE METHOD OF ENHANCING THE CONTROLLABILITY OF AIRCRAFT AT MODERATE-TO-HIGH ANGLES-OF-ATTACK (AOA) BY CONTROLLING THE FOREBODY VORTEX FLOW WITH ROTATABLE NOSE-BOOM STRAKES. THE IDEA IS TO CONTROL THE ASYMMETRY OF THE NOSE-BOOM WAKE BY PLACING SMALL, MOVABLE STRAKES ON THE NOSE-BOOM. THE WAKE THEN ACTS AS A CONTROLLED PERTURBATION ON THE FOREBODY FLOW AND SUBSE ...
