PROCESSING OF SAR DATA IN REAL TIME REQUIRES HIGH SPEED COMPUTATION DEVICES CURRENTLY BEYOND THE STATE-OF-THE-ART OF CONVENTIONAL METHODS. DESIRED PROCESSORS MUST ALSO BE SMALL, RUGGED AND LOW POWER TO BE DEPLOYED ON AIRCRAFT. OPTICAL TECHNIQUES CAN SATISFY THESE REQUIREMENTS WITH IMAGINATIVE ARCHITECTURES. THIS PROPOSAL PRESENTS AN INNOVATIVE APPROACH FOR REAL TIME SAR IMAGE RECONSTRUCTION THAT C ...

AN INNOVATIVE APPROACH TO FORMING A NULL IN THE SECONDARY PATTERN OF A REFLECTOR ANTENNA IS DEVELOPED BY THIS PROJECT. AN ELECTRONICALLY CONTROLLABLE REFLECTIVE SURFACE BEING DEVELOPED ON A NASA SBIR IS THE STARTING POINT FOR THE WORK. THIS PROJECT EXTENDS THE PERFORMANCE OF THE SURFACE SO THAT IT IS USEFUL AS A NULL FORMER. THE RESULT IS CONSIDERABLY REDUCED COST OF NULL STEERING ANTENNAS. THE DE ...

NONDESTRUCTIVE EVALUATION OF MUNITIONS PRESENTS SPECIAL PROBLEMS THAT CANNOT BE SOLVED WITH CONVENTIONAL TECHNIQUES. AN ELECTRONIC X-RAY IMAGING SYSTEM WILL BE STUDIED TO DETERMINE THE FEASIBILITY OF ITS USE IN ADVANCED RADIOGRAPHIC IMAGING TECHNIQUES SUCH AS REMOTE ON-LINE INSPECTION, MULTISPECTRAL RADIOGRAPHY AND BACKSCATTER TOMOGRAPHY.

THIS PROPOSAL DESCRIBES A FEASIBILITY STUDY FOR IMPLEMENTING A REALTIME, THREE-DIMENSIONAL CLOUD MODEL TO SUPPORT REENTRY VEHICLE TEST OPERATIONS. AN EXISTING RESEARCH CLOUD MODEL WOULD BE INTERFACED TO A MESOSCALE ATMOSPHERIC MODEL. THE COMBINED MODELING SYSTEM WOULD BE ADAPTED FOR USE AT THE KWAJALEIN MISSILE RANGE (KMR). FORECASTS OF DETAILED CLOUD FEATURES SUCH AS WATER CONTENT, RADAR REFLECTI ...

FUTURE MILITARY SPACE MISSIONS WILL REQUIRE 10-100 KILOWATTS OF SUSTAINED POWER WITH PEAK/PULSE POWER LEVELS OF 100 KW TO 100 MW. ELECTROCHEMICAL ENERGY STORAGE SYSTEMS WHICH CAN DELIVER HIGH POWER DENSITY YET OFFER HIGH ENERGY DENSITY NEED TO BE DEVELOPED. THESE RECHARGEABLE BATTERIES MUST HAVE DURABILITY AND COMPOSITION INVARIANCE FOR OVER 30,000 CYCLES. BOTH OF THE ELECTRODE REACTIONS IN THE ME ...

AN "INTELLIGENT" MECHANISM TO CONTROL AIRCRAFT TURBINE ENGINE COOLDOWN UTILIZING INTEGRAL SENSORS, LOGIC, DRIVE AND FAIL-SAFE, FOR EXTENDING THE PERFORMANCE LIFE OF AIRCRAFT GAS TURBINE ENGINES IS PROPOSED. AIRCRAFT TURBINE ENGINES ARE PRECISELY MADE AND CONTROLLED MECHAISMS UNTIL SHUTDOWN. THEN, HEAT SOAK AND SOAKBACK PHENOMEN DELETERIOUSLY AFFECT ENGINE PERFORMANCE, LIFE, MAINTENANCE COSTS AND L ...

EXPITAXIAL CUPROUS CHLORIDE ON SILICON SUBSTRATES (CUCL:SI) EXHIBITS UNIQUE PHYSICAL PROPERTIES TO TEMPERATURES ABOVE 200 DEG C THAT, HERETOFORE, HAVE ONLY BEEN OBSERVED IN LOW TEMPERATURE SUPERCONDUCTING MATERIALS. THESE PROPERTIES APPEAR TO BE LOCALIZED AT THE INTERFACE BETWEEN THE CUCL LAYER AND SI SUBSTRATE. THE VERY LOW RESISTANCE STATE APPEARS TO EXHIBIT A CRITICAL CURRENT THAT MAY BE RELATE ...

EXISTING GLASS MATRIX LASERS UTILIZE NEODYMIUM DOPING OF A SILICATE MATRIX. THE INABILITY TO USE A SIO2 MATRIX RESULTS IN AN EFFICIENCY OF 3% OR LESS. THE LOW THERMAL CONDUCTIVITY OF GLASS COUPLED WITH THE RELATIVELY HIGH COEFFICIENT OF THERMAL EXPANSION OF THE SILICATES LIMITS THE OUTPUT INTENSITY AND PULSE RATE IN ORDER TO PREVENT DEDOCUSING AND FILAMENTARY BREAKDOWN FROM THE THERMAL EFFECTS. TH ...
