In the proposed effort, we will leverage this extensive experience and capabilities to realize a frequency agile mmW radiometer that can cover the range of DC-110 GHz and can be scaled to DC-200 GHz under Phase II. Ours is a photonic system that multiplies and up-coverts a low-frequency reference signal onto an optical carrier (laser) using EO modulation, then uses the modulation sidebands to inj ...

Training in the symptoms of Spatial Disorientation (SD) has shown to be valuable in aiding pilots to recognize its onset and provide a means for mitigating its effects, but such demonstrations have traditionally been associated with specialized equipment and devices. Since the vast majority of pilots for the commercial aviation jet fleet are trained (or recertified) on 6-degree-of-freedom (DOF) h ...

NEW LIGHTING TECHNOLOGIES, INCLUDING FIBER OPTICS AND HIGH EFFICIENCY ARC SOURCES, WILL BE APPLIED IN THIS PHASE I PROJECT TO DEVELOP INNOVATIVE APPROACH LIGHTING SYSTEMS (ALS) FOR AIRPORT RUNWAYS. THE GOAL IS TO REPLACE THE LARGE NUMBER OF INDIVIDUAL INCANDESCENT SPOT LIGHTS PRESENTLY IN SUCH SYSTEMS WITH REMOTE SOURCES COUPLED TO OPTICAL WAVEGUIDES THAT WILL TRANSMIT AND PROJECT THE REQUIRED HIG ...

THE PHASE 1 PROJECT INVESTIGATES WHETHER RECENT ADVANCES IN OPTICAL AND THERMAL DETECTORS, AND FIBER-OPTICS CAN BE APPLIED TO MONITOR INDIVIDUAL LAMPS IN AIRPORT APPROACH LIGHTING SYSTEMS. PHASE 1 CONCENTRATES THE TECHNICAL EFFORT ON RESEARCH TO MATCH LAMP AND SENSOR CHARACTERISTICS, A DEFINITION OF THE LAMP NETWORK LINE IMPDEANCE AND NOISE MODELS, AND THE DEVELOPMENT OF APPROPRIATE SERIES POWER-L ...

SCREENING BAGGAGE AND PASSENGERS FOR CONCEALED WEAPONS AND EXPLOSIVES REMAINS A SIGNIFICANT COMPONENT OF THE AVIATION SECURITY SYSTEM. RECENT TECHNOLOGICAL ADVANCES ENHANCE OUR ABILITY TO OBTAIN INFORMATION ABOUT THE SHAPE AND COMPOSITION OF CONCEALED ITEMS. HOWEVER, THE DEVELOPMENT OF DECISION SUPPORTS TO PRESENT THIS INFORMATION TO THE OPERATOR HAS LAGGED BEHIND. HOW A SYSTEM PRESENTS INFORMATIO ...

NETROLOGIC PROPOSES TO BUILD A NAVIGATION SYSTEM FOR SHIPS WHICH INTEGRATES GPS AND LORAN-C. THE GPS SYSTEM PROVIDES ASF ERROR CORRECTION TO LORAN-C SO THAT THE CORRECTED LORAN-C IS ABLE TO FURNISH NEAR GPS QUALITY GEOGRAPHICAL LOCATION INFORMATION. IN AREAS WHERE DGPS IS AVAILABLE THE DGPS SIGNAL CAN BE FURNISHED AS A REFERENE TO REALIZE CORRESPONDING GAINS IN ACCURACY FOR CORRECTED LORAN0-C. A N ...

A CONCEPT FOR THE DETECTION OF CORROSION IN AGING AIRCRAFT USING ACOUSTIC EMISSION MONITORING IS PROPOSED. CORROSION WILL BE LOCATED THROUGH THE EFFECT THAT IT HAS ON AIRFRAME STRENGTH (10% THINNING RESULTS IN 50% FATIGUE LIFE REDUCTION). ACOUSTIC EMISSION TECHNOLOGY USED ON THE F-111 FIGHTER/BOMBER WILL BE ADAPTED FOR USE ON COMMERCIAL AIRCRAFT. PRELIMINARY CONCEPT TESTING ON A BOEING 720B HAS RE ...

THE WORK PROPOSED HEREIN CENTERS AROUND A METHOD TO OBSERVE AND MEASURE THE STATE OF DISTRESS (INCLUDING CRACK DEPTH) INASPHALTIC AND PORTLAND CEMENT CONCRETE RUNWAY PAVEMENTS. THE METHOD OF THIS PROPOSED WORK EMPLOYS A VIDEO IMAGE PROCESSING PROCEDURE THAT USES THE VIDEO IMAGE AND ASSOCIATED SOFTWARE AND FIRMWARE TO CAPTURE THE DISTRESSED SITE AND QUANTIFY THE DISTRESS THROUGH PATTERN RECOGNITION ...
