INNOVATIVE APPROACHES ARE DESCRIBED IN THIS PROPOSAL FOR SUPPRESSING FREQUENCY MODULATION ON A SINUSOIDAL CARRIER. PARTICULAR EMPHASIS IS DIRECTED TO THE SUPPRESSION OF IDENTIFIABLE COMPONENTS OF A COMPOSITE MODULATION PROCESS FOR THE PURPOSE OF RETAINING, FOR SEPARATE MEASUREMENT, ANY FORM OF RANGE-RATE DOPPLER SHIFT/MODULATION PRESENT. THE PROPOSED EFFORT WILL CONSIST OF AN ANALYTICAL STUDY FOR ...

INTERMETALLIC COMPOUNDS ARE KNOWN FOR THEIR HIGH MELTING POINTS AND CORROSION AND OXIDATION RESISTANCE. MANY OF THESE COMPOUNDS HAVE LOW DENSITIES AND VERY HIGH STRENGTHS AND, THEREFORE, ARE OF INTEREST FOR HIGH TEMPERATURE AEROSPACE AND SPACE STRUCTURE APPLICATIONS. HOWEVER,CONVENTIONAL PROCESSING OF INTERMETALLIC COMPOUNDS SUFFERS SEVERE LIMITATIONS: REACTIONS WITH CONTAINERS, POROSITY, CONTAMIN ...

THE WASTE HEAT EXCHANGER IS OFTEN THE LARGEST SINGLE COMPONENT IN DIESEL-EXHAUST POWERED AIR CONDITIONING SYSTEMS, AND ON ACCOUNT OF ITS HIGH MATERIAL CONTENT, IS OFTEN THE HEAVIEST AND MOST COSTLY AS WELL. THE NEED EXISTS FOR A HEAT EXCHANGER DESIGN AND FABRICATION TECHNIQUE WHICH IS COMPACT AND LIGHTWEIGHT, RESISTS FOULING FROM EXHAUST GASES, IS EASILY CLEANED, USES INEXPENSIVE MATERIALS, AND IS ...

THE RECENT DISCOVERY OF SUPERCONDUCTIVITY AT HIGH TEMPERATURE (90 DEG K) IN COPPER CONTAINING CERAMICS HAS RESULTED IN A RAPID ACCELERATION IN SUPERCONDUCTOR RESEARCH. PRODUCTION TECHNIQUES ARE BEING EXAMINED FOR THE FABRICATION OF BULK AND THIN FILM SAMPLES. THE CURRENTLY USED PROCESSES FOR MAKING THIN FILMS OF SUPERCONDUCTORS ARE PRIMARILY LIMITED TO EXPENSIVE, SMALL SCALE, LABORATORY TECHNIQUES ...

THE WHITE SANDS MISSILE RANGE GAMMA RAY FACILITY IS USED TO QUALIFY MILITARY EQUIPMENT FOR RADIATION HARDNESS. ISOTOPIC SOURCES OF 60 CO AND 137 CS ARE USED TO PRODUCE INTENSE GAMMA RAY FIELDS THAT ALLOW TESTING OF ELECTRONIC SYSTEMS IN ENVIRONMENTS THAT APPROXIMATE ANTICIPATED NUCLEAR BATTLEFIELD CONDITIONS. RECENTLY IT HAS BECOME CLEAR THAT DOSE ENHANCEMENT EFFECTS PRODUCED BY A LOW ENERGY COMPO ...

THE OBJECTIVE OF THIS RESEARCH IS TO DEMONSTRATE THE FEASIBILITY OF FUSING DATA OBTAINED SIMULTANEOUSLY FROM VISIBLE, INFRARED AND RADAR SENSORS, TO PROVIDE A HERETOFORE UNOBTAINABLE SURVEILLANCE CAPABILITY.THE DIFFICULTIES ASSOCAITED WITH SENSOR FUSION WHICH WILL BE ADDRESSEDINCLUDE THE DIFFERENT FIELDS OF VIEW, DIFFERENT MEASUREMENTS, DIFFERENT RESOLUTIONS, AND DIFFERENT POSITIONS AND VELOCITIES ...

A REQUIREMENT EXISTS TO PROVIDE OCULAR PROTECTION TO TROOPS AT RISK FROM LASER ENERGY EXPOSURE AND BALLISTIC FRAGMENTS WHILE MAINTAINING ESSENTIAL VISUAL PERFORMANCE. SINCE HOSTILE LASER BEAMS MAY BE AT UNEXPECTED WAVELENGTHS, THE USUAL NOTCH FILTER IS NOT A COMPLETE ANSWER TO THE PROBLEM. THIS LABORATORY PROPOSES A COMPLETELY DIFFERENT ANSWER: AN INTERFERENCE FILTER THAT BLOCKS ALL OF THE VISIBLE ...
