AER PROPOSES TO DEVELOP A NEW CONCEPT IN PROVIDING WEATHER \FORECASTING FOR INDUSTRY, MADE POSSIBLE BY THE DECREASING COSTS OF POWERFUL COMPUTERS. IMPROVED SHORT-RANGE FORECASTS WOULD BE OBTAINED BY RUNNING A MODEL ON THE USER'S COMPUTER. THE MODEL WOULD ACCESS THE FORECASTS OF THE NATIONAL METEROLOGICAL CENTER AND MODIFY THEM THROUGH A DETAILED SIMULATION OF THE PHYSICS OF ATMOSPHERIC PROCESSES,T ...

THERE ARE ONLY A FEW RADIOMETRIC STANDARDS AVAILABLE IN THE 115-350 NM WAVELENGTH REGION. AMONG THEM ARE THE ARGON MINI-ARC AND THE DEUTERIUM LAMP. BOTH LAMPS PROVIDE STABLE SOURCES OF UV/VUV RADIATION, AND CAN BE CALIBRATED BOTH IN RADIANCE AND IRRADIANCE. HOWEVER, EACH HAS DISADVANTAGES THAT LIMIT ITS USEFULNESS AS A BENCHTOP OR SPACE-QUALIFIED STANDARD. ONE POSSIBLE ALTERNATIVE SECONDARY RADIOM ...

THIS PROPOSAL DEALS WITH THE DEVELOPMENT OF A COMPUTER SIMULATION OF A GENERALIZED AIR-TRAFFIC CONTROL RADAR. IT INCLUDES THE ABILITY TO REALISTICALLY SIMULATE RADAR RETURNSFROM GROUND CLUTTER AND VARIOUS KINDS OF HAZARDOUS WEATHER. THE SIMULATION WILL ALSO REPRESENT THE EFFECT OF CLUTTER ANDWEATHER RETURN LEAKAGE THROUGH THE RADAR'S ANGLE AND RANGE SIDELOBES. THE PROPOSED SIMULATION WILL ALLOW TH ...

THE PROPOSED RESEARCH INVESTIGATES THE FEASIBILITY OF DEVELOPMENT AN INNOVATIVE ICEPHOBIC COATING THAT WILL PREVENT THE ACCRETION OF ICE ON SURFACES, SUCH AS RUNWAYS VIA THE PHENOMENON OF PASSIVE DYNAMICS. THE UNDERLYING CONCEPT IS TO INCORPORATE SPECIAL MATERIALS INTO EXISTING RUNWAY COATING FORMULATIONS WHICH, ALTHOUGH PASSIVE UNDER NORMAL CONDITIONS, BECOME DYNAMIC WHEN ICE FORMING CONDITIONS P ...

MICROWAVE LANDING SYSTEM WILL INCREASE THE SAFETY OF TERMINAL AREA NAVIGATION, AND THE EFFICIENCY OF AIRSPACE UTILIZATION AT CONGESTED AIRPORTS WITH THE USE OF NAVIGATIONSYSTEMS BLENDING MLS POSITION INFORMATION WITH THAT PROVIDED BY ON-BOARD SENSORS. THE OBJECTIVE OF THISSTUDY IS TO DEVELOP LOW COST MLS BASED NAVIGATION SYSTEM FOR USE ON GENERAL AVIATION, COMMUTER, AND SHORT-HAUL TRANSPORT AIR CR ...

AN ENHANCED MARINE NAVIGATION BEACON TRANSMITTER IS PROPOSEDWHICH INTEGRATES THE TECHNOLOGIES OF POWER CONVERSION AND RFAMPLIFICATION AND EMPLOYS COMPONENTS AND A TOPOLOGY HAVING EXTREMELY LOW LOSSES. THE ENHANCED BEACON, IN WHICH OPERATING WAVEFORMS ARE DIGITALLY GENERATED, PRODUCES THE SAME SIGNAL WHICH IS TRANSMITTED BY EXISTING SYSTEMS.

THE PRESENT DATUM MARKER BUOY REQUIRES EXCESS VALUABLE AIRCRAFT TIME DURING A SEARCH AND RESCUE. FINDING AND HOMING IN ON THE VHF MARKER WASTES TIME. THE OPPORTUNITY ISTO DEVELOP A GPS-BASED, SELF-LOCATING BUOY WHICH TRANSMITS ITS ACCURATE POSITION VIA SATELLITE COMMUNICATIONS IN REAL TIME. THE OBJECTIVES OF THIS PROGRAM ARE TO: (1) PRODUCE A WORKING PROTOTYPE TO DEMONSTRATE THAT THE GPS NAVIGATIO ...
