ADVANCED ESM AND ANTIRADIATION MISSILES HAVE MADE OPERATION OF A RADAR ON THE MODERN BATTLEFIELD VERY RISKY. A POPULAR APPROACH TO MAKING RADARS SURVIVABLE IS TO USE PASSIVE RECEIVERS FOR PROCESSING TARGET RETURNS USING NON-COLOCATED TRANSMITTERS; THE PASSIVE RECEIVERS ARE INVULNERABLE TO INTERCEPT WHILE PERFORMING THEIR RADAR PROCESSING. UNFORTUNATELY THIS PASSIVE CONVERTNESS OF SUCH BISTATIC REC ...

ORDERED POLYMER MATERIALS PROCESSED FROM LIQUID CRYSTALLINE SOLUTIONS CAN BE USED WITH GLASS PROCESSED BY THE SOL-GEL METHOD TO PRODUCE A COMPOSITE WITH HOMOGENEITY ON A VERY SMALL SCALE. SUCH A "MICROCOMPOSITE" MATERIAL ROD-LIKE POLYMER PBT (POLY PHENYLENE BENZOBISTHIAZOLE) AND GLASS, SUCH AS SILICA, OFFERS SOME POTENTIAL ADVANTAGES. PBT WOULD PROVIDE HIGH TENSILE STRENGTH, STIFFNESS, TOUGHNESS, ...

ADVANCED COLUMBIUM ALLOYS HAVING IMPROVED HIGH TEMPERATURE MECHNICAL PROPERTIES AND OXIDATION RESISTANCE ARE OF LONG-TERM INTEREST TO THE U.S. AIR FORCE FOR POTENTIAL APPLICATIONS AS TURBINE VANES IN AIRCRAFT PROPULSION SYSTEMS. THERE IS AN OPPORTUNITY TO DEVELOP IMPROVED COLUMBIUM ALLOYS USING THE PRINCIPLES OF RAPID SOLIDIFICATION AND POWDER METALLURGY. MARKO MATERIALS HAS DEVELOPED A PROCESS AN ...

RECENTLY, RESEARCH AT SEVERAL GOVERNMENT FACILITIES HAS RESULTED IN SIGNIFICANT ADVANCES IN BOTH THE ELECTRONIC AND DETECTOR ASPECTS OF INTEGRATING RADIATION DOSIMETERS. ONE PARTICULAR APPROACH, THE LOS ALAMOS MULTIDETECTOR RADIATION MONITOR, IS A MICROPROCESSOR BASED INSTRUMENT, CAPABLE OF INTERROGATING SEVERAL DIFFERENT NUCLEAR DETECTORS SIMULTANEOUSLY. ALTHOUGH USING GEIGER TUBES FOR THE GAMMA ...

WE PROPOSE TO DEVELOP THE TOOLS FOR THE DETERMINATION AND EVALUATION OF KNOWLEDGE BASES FOR INFRARED IMAGE INTERPRETATION SYSTEMS. OUR APPROACH IS BASED ON A THREE DIMENSIONAL MODELING SYSTEM WHICH WILL CONTAIN PHENOMENOLOGY FROM WHICH IMAGES CAN BE SYNTHESIZED. THE THREE DIMENSIONAL MODEL WILL BE DEVELOPED TO THE LEVEL OF DETAIL WHICH IS CONSISTENT WITH THE SPATIAL AND THERMAL RESOLUTIONS OF THE ...

APPLIED RESEARCH AND ENGINEERING, INC. PROPOSES TO DEVELOP A COMMUNICATION SUBSYSTEM FOR MULTISTATIC RADAR MISSION APPLICATIONS. THE APPROACH EMPLOYS BIT-SLICE MICROPROCESSOR TECHNIQUES TO INTEGRATE THE MULTISTATIC RADAR SIGNAL AND COMMUNICATION SUBSYSTEM DATA PROCESSING FUNCTIONS TO PROVIDELOW DATA RATES FOR SENSOR WAVEFORM INFORMATION DISTRIBUTION.THE PHASE I EFFORT WILL DEFINE AND DEVELOP THIS ...

A RESEARCH PROGRAM IS PROPOSED TO DEVELOP THE METHODOLOGY FOR A WAKE TURBULENCE MODEL THAT TAKES INTO ACCOUNT THE INTERACTION BETWEEN LARGE-SCALE, LOW FREQUENCY, AND SMALL-SCALE, HIGH FREQUENCY COMPONENTS OF TURBULENT FLOW. THE MODEL WILL BE CONSTRUCTED BY FORMULATING THE GOVERNING EQUATIONS FOR THE BEHAVIOR OF THE LARGESCALE STRUCTURE, COMBINED WITH EXISTING MODELS FOR THE EFFECT OF THE BACKGROUN ...
