POTENTIAL SORTING TECHNIQUES FOR USE BY RADAR WARNING RECEIVERS (RWR) AND DECEPTION ELECTRONIC WARFARE (DECM) SYSTEMS ARE IDENTIFIED FOR HANDLING ADVANCED EMITTERS DISPLAYING COMPLEX MODULATION TYPES. THEIR EXPECTED PERFORMANCE IS ANALYZED IN TERMS OF THEIR CAPABILITY TO MEET PROCESSING SPEED, ACCURACY, AND PARAMETER MEASUREMENT REQUIREMENTS. THE INVESTIGATION ALSO DESCRIBES THE HARDWARE AND SOFTW ...

We propose to develop algorithms which can be used to assimilate separate satellite data sets of important geophysical parameters into global, gridded data sets. The data assimilation program will be cast as a retrieval problem in which the true, instrument independent global distribution is retrieved from the combined satellite data set. This problem will be solved using the method of optima ...

IMAGING SPECTRORADIOMETERS COMMONLY USE A POLYCHROMATOR TYPE INSTRUMENT IN CONJUNCTION WITH AN IMAGING ARRAY. SUCH INSTRUMENTS ARE LARGE IN SIZE AND WEIGHT, AND REQUIRE DELICATE ALIGNMENT OF THE DISPERSION ELEMENT IN RELATION TO THE ARRAY. A NOVEL CONCEPT USES NO DISPERSION ELEMENT BUT A PROPRIETARY ANAMORPHIC OPTICAL SYSTEM, AND A SPECIAL DATA REDUCTION ALGORITHM, PRODUCES A PERMANENTLY ALIGNED, ...

The proposal relates to a study leading to the definition of requirements, trade offs and design parameters for a large (144Gb) solid state buffer memory for use in the ATARS and and EO-LOROPS systems. This buffer is intended to relieve operating demands on present digital tape units, so to improve their reliability. The tasks will consider interface requirements from the sensors, optimum architec ...

Proposed is a novel method of controlling mass storage devices (MSD) on power up, so as to force an immediate write at the location contiguous to that last written prior to power down. This technique is important for reducing power consumption in battery operated data logging systems employing MSDs. It obviates the necessity for scanning the entire contents until the last written location is found ...

RELIABILITY AND CIRCUIT DENSITY OF STANDARD ELECTRONIC MODULES (SEM) CAN BE INCREASED SIGNIFICANTLY BY TAILORING THERMOPHYSICAL PROPERTIES OF THE HEAT SINK MATERIALS. NEWLY DEVELOPED TECHNIQUES FOR MANUFACTURING METAL MATRIX COMPOSITES (MMC) BY VAPOR DEPOSITION METHODS WILL BE USED TO DEMONSTRATE LIGHT-WEIGHT, HIGH-PERFORMANCE HEAT SINKS HAVING THERAML CONDUCTIVITIES IN EXCESS OF 300 W/M-K AS WELL ...

FABRICATION OF A LOW-NOISE MICROWAVE RECEIVER USING HIGH TEMPERATURE SUPERCONDUCTORS DEPENDS UPON THE ABILITY TO FABRICATE INDIVIDUAL SUPERCONDUCTING MICROWAVE COMPONENTS, DETERMINATION OF THE OPTIMAL USAGE OF SUPERCONDUCTING COMPONENTS IN CONJUNCTION WITH CONVENTIONAL (NON SUPERCONDUCTING) ONES, AND SPECIFICATION OF A RESULTING DESIGN. SEI WILL DESIGN, FABRICATE, AND TEST AN EDGE-COUPLED FILTER A ...

The principal objective of, this effort shall be to demonstrate techniques which shall reduce the of fect of f low noise on the performance of sonar on underwater vehicles, and which permit effective operation at higher speeds. Flow over a sonar which is installed at the bow of an axisymmetric vehicle may be laminar, transitional, or turbulent, dependent upon the speed of the body, the pressu ...
