THE PRIMARY OBJECTIVE OF THIS PROJECT IS TO PROVIDE THE DESIGNER OF AN TI-RADIATION HOMING MISSILES WITH THE INFORMATION NECESSARY TO STRUCTURE FUTURE STUDIES AND TECHNOLOGY PROGRAMS AIMED AT DEVELOPING AN ANTI- RADIATION MISSILE CAPABLE OF HOMING ON THREAT RADIATION MISSILE CAPABLE OF HOMING THREAT RADARS UTILIZING SPREAD SPECTRUM TECHNIQUES. THIS INVOLVES THE FOLLOWING TWO TASKS: 1. DEFINE THE C ...

THIS RESEARCH ADDRESSES TECHNIQUES AND MATERIALS FOR ON-ORBIT MAINTENANCE AND REFURBISHMENT OF THERMAL CONTROL SURFACE COATINGS USED ON LONG-LIFE SPACECRAFT. IN MANY CASES, CONSERVATIVE ASSUMPTIONS ON THE EFFECTS OF LONG-TERM DEGRADATION HAVE DRIVEN THE DESIGN OF SPACECRAFT THERMAL SYSTEMS TOWARD OVER CAPACITY WHICH RESULTS IN WEIGHT, SIZE, COMPLEXITY, AND COST PENALTIES. IF CRITICAL SURFACES COUL ...

THIS PROPOSAL DESCRIBES THE EVALUATION OF REQUIREMENTS FOR REMOTE WEATHER SAMPLING SYSTEMS APPLIED TO A SPECIFIED UNMANNED METEOROLOCIALRECONNAISSANCE AIRCRAFT. DATA TO BE GATHERED INCLUDE CLOUD STATISTICS, WATER CONTENT AND PARTICLE SIZE, DENSITY AND WIND. LIQUID WATER CONTENT MEASUREMENT IS CONSIDERED BASED ON USING EXISTING INSTRUMENTS AND THE PROPOSER'S CONCEPTUAL DESIGN OF A NEW INSTRUMENT. D ...

THE LIQUID WATER CONTENT OF CLOUDS IS ONE OF THE MOST FUNDAMENTAL QUANTITIES IN THE ATMOSPHERE. YET, NO INSTRUMENT HAS BEEN DEVELOPED FOR MEASURING LIQUID WATER CONTENT IN BOTH LIQUID AND SOLID PHASE CLOUDS. THIS IS A PROPOSAL TO DEVELOP THE PRELIMINARY DESIGN OF AN AIRBORNE INSTRUMENT FOR MEASURING LIQUID WATER IN ALL NATURAL CLOUDS, WITH EITHER LIQUID OR ICE CLOUD PARTICLES. THE SYSTEM WILL FEAT ...

EXFLUOR RESEARCH CORPORATION HAS DEVELOPED GENERAL PROCEDURES FOR PREPARING HIGH MOLECULAR WEIGHT PERFLUOROALKYL ETHER ELASTOMERIC POLYMERS. ONE PROCEDURE CONSISTS OF FIRST SYNTHESIZING THE HYDROCARBON ANALOGUE OF THE DESIRED PERFLUORO COMPOUND FOLLOWED BY REPLACEMENT OF THE HYDROGEN WITH FLUORINE USING A CONTROLLED REACTION WITH ELEMENTAL FLUORINE. THIS PROCEDURE ALLOWS ONE TO PREPARE FLUOROCARBO ...

A METHODOLOGY FOR THE APPLICATION OF A RULE INDUCING EXPERT SYSTEM BUILDER TO DEVELOP AN EXPERT SYSTEM FOR AIRCREW AVIONICS SYSTEMS MISSION TRAINING WILL BE DEVELOPED AND TESTED. THIS METHODOLOGY WILL PERMIT TRAINING PERSONNEL, RATHER THAN AI RESEARCHERS OR SPECIALISTS, TO DEVELOP SUCH EXPERT SYSTEM APPLICATIONS. THE EXPERT SYSTEM WILL BE INTEGRATED WITH A REAL-TIME AVIONICS SYSTEMS PART-TASK SIMU ...

THE PROBLEM OF PREDICTING DETECTION/IDENTIFICATION PROBABILITIES FOR A SMALL, MOBILE ICBM IS TO BE ADDRESSED THROUGH A SPECTRAL MODEL INCLUDING TARGET REFLECTIVITY, BACKGROUND REFLECTIVITY, SOLAR IRRADIANCE, ATMOSPHERIC TRANSMITTANCE/SCATTERING, SENSOR SENSITIVITY RESPONSE, SENSOR SPECTRAL RESPONSE, AND DETECTION/IDENTIFICATION RESOLUTION CRITERIA. THE MODEL IS TO USE A FRACTAL STATISTICAL BASIS F ...
