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 ...

A PLAN FOR THE DEVELOPMENT OF A MESOSCALE WEATHER NOWCASTING SYSTEM IS PROPOSED. THAT SYSTEM WOULD BE USED AS A TACTICAL DECISION AID FOR SUPPORT OF TACTICAL ARMY OPERATIONS. THE SYSTEM WOULD BE COMPOSED OF MODULAR SENSOR PACKAGES, A TELEMETRY SYSTEM, A FLEXIBLE SYSTEM OF SENSOR DEPLOYMENT, AND A MICROPROCESSOR BASED TACTICAL COMPUTER SYSTEM FOR THE ANALYSIS AND DISPLAY OF DATA COLLECTED. THE PROP ...

MOST LASER SCANNING SYSTEMS ARE MECHANICAL, UTILIZING A MOTOR TO ROTATE A PRISM, MIRROR, OR HOLOGRAPHIC GRATING. SUCH MECHANICAL SYSTEMS ARE OR RELATIVELY LARGE SIZE AND MASS. THERE IS A NEED FOR A SOLID STATE SCANNING DEVICE WHICH WOULD OFFER BENEFITS OF REDUCED SIZE AND MASS, NO MOVING PARTS, IMPROVED RELIABILITY, LOW COSTS, AND LOW POWERREQUIREMENT. WE PROPOSE TO DEVELOP AN INTEGRATED OPTICS (I ...

THE OBJECTIVE OF THE PROPOSED EFFORT IS TO REDUCE THE SIZE, WEIGHT, AND COST OF THE RELAY OPTICS OF THE AIRCRAFT HEAD UP DISPLAY (HUD), BY REPLACING IT WITH TRANSMISSION HOLOGRAPHIC LENSES. HOLOGRAPHIC LENSES ARE VERY LIGHT AND CAN BE MANUFACTURED AT VERY LOW COSTS. APPLICATIONS OF HOLOGRAPHIC LENSES TO HUD WERE LIMITED IN THE PAST, DUE TO WIDE SPECTRAL BAND OF THE HUD - CATHODE RAY TUBE (CRT). HO ...

A SPECTRALLY AGILE BASED UPON A TUNABLE FILTER CAN EFFECTIVELY MEASURE INFRARED BACKGROUND, TARGETS, AND OBSCURANT CLOUDS. AN INTEGRATED OPTICS INTEGRATED FILTER (IOTF) PLACED IN FRONT OF THE SENSOR FOCAL PLANE OR INTEGRATED WITH THE FOCAL PLANE DETECTORS CAN BE USED TO SELECT WAVEBAND LOCATION AND BANDWIDTH IN THE INFRARED. A SPECIFIC CONCEPT FOR THE FILTER IS PROPOSED BASED UPON A MACHZEHNDER IM ...

SUBSTANTIAL IMPROVEMENTS IN TEST EFFICIENCY RESULTING FROM THE USE OF ITEM RESPONSE THEORY AND COMPUTERIZED TESTING MAY BE COMPROMISED IF DUPLICATE OR SUBSTANTIALLY SIMILAR TEST ITEMS APPEAR IN ITEM POOLS. THE PROPOSED PROJECT WILL DESIGN, IMPLEMENT, AND EVALUATE SEVERAL PROCEDURES FOR DETECTING SUBSTANTIALLY SIMILAR ITEMS IN AN ITEM POOL. THESE PROCEDURES WILL RANGE FROM SIMPLE ELEMENT AND TOKEN ...

ULTRASONIC NONDESTRUCTIVE TESTING HAS BECOME THE METHOD OF CHOICE FOR THE QUALITY ASSURANCE OF ADVANCED COMPOSITE MATERIALS. THE PROPOSED RESEARCH PROGRAM COVERS THE DEVELOPMENT OF A COMPUTER-BASED NDT METHOD FOR DETERMINING LOCAL FIBER VOLUME FRACTION AND RESIN POROSITY IN PRACTICAL LAMINATED COMPOSITES. THE COMPUTER ALGORITHMS WILL BE BASED ON EARLIER STUDIES THAT HAVE BEEN SUCCESSFUL FOR UNIDIR ...
