WE PROPOSE TO DEMONSTRATE AN OPTICAL ANALOG-TO-DIGITAL CONVERTER FOR MICROWAVE ANALOG SIGNALS WHICH UTILIZES A SINGLE ELECTROOPTIC BROADBAND VELOCITY MATCHED TRAVELLING WAVE MODULATOR BUT WITH MULTIPLE PULSED OPTICAL BEAMS TO SAMPLE THE SIGNAL AND MULTIPLE STANDARD ELECTRONIC A/D'S TO ACCOMPLISH THE CONVERSION IN PARALLEL. THE DIGITAL OUTPUT WORDS APPEAR ON MULTIPLE SETS OF LINES APPROPRIATE FOR A ...

THE POLARIZATION CHARACTERISTICS OF AIRCRAFT INFRARED SIGNATURES HAVE BEEN STUDIED AS A MEANS TO ENHANCE THE PERFORMANCE OF LONG RANGE PASSIVE INFRARED DETECTION SYSTEMS OPERATING IN THE PRESENCE OF CLUTTER. THESE STUDIES ALSO GENERATED EVIDENCE THAT THE AMOUNT AND ANGLE OF POLARIZATION AS WELL AS ITS SPATIAL DISTRIBUTION ARE UNIQUE BETWEEN DIFFERENT TYPES AND CLASSES OF AIRCRAFT. IT MAY BE POSSIB ...

THE PROPOSED PROGRAM WOULD PROVIDE THE AIR FORCE BALLISTIC SYSTEMS DIVISION (BSD) WITH AN ENGINEERING LEVEL SIGNATURE MODELING CAPABILITY FOR VARIOUS TYPES OF REENTRY VEHICLES (RVS) DURING THE MIDCOURSE PHASE. THE PRESENT AERODYNE RESEARCH, INC. (ARI) SPIRITS SIGNATURE MODEL OFFERS THE BASSIS FOR THE MODELING CAPABILITY IN THE ULTRAVIOLET (UV) THROUGH THE INFRARED (IR) SPECTRUM. THE SPIRITS MODEL ...

WE PROPOSE TO DEVELOP A PATTERNED ETCHING TECHNIQUE FOR INFRARED DETECTOR ARRAYS BASED ON PHOTO-INDUCED ETCHING OF HGCDTE THAT IS COMPATIBLE WITH THE ULTRA-HIGH VACUUM ENVIRONMENT OF A MOLECULAR BEAM EPITAXY APPARATUSES. THE PHASE I RESEARCH FOCUSES ON ESTABLISHING THE EFFICACY OF SUITABLE GAS PHASE PRECURSORS FOR THE ETCHING PROCESS. IF THE PHASE I RESEARCH IS SUCCESSFUL, OPTICAL PROJECTION TECHN ...

Nighttime operations are very attractive for the U.S. Armed Forces since these conditions generally maximize their advantage over the opposing forces. The deployment of IR countermeasures to protect aircraft from heat-seeking missiles, however, may remove the advantage of nighttime conditions and expose the aircraft to anti-aircraft artillery and small arms fire. Therefore, a need exists for an IR ...

High intensity cooling of expansion turbine blades is proposed, using a self-stabilized evaporation/condensation process within each blade. The result is low blade structural temperature, with waste heat delivered to a low pressure air flow. This is a key technology requirement for development of a fully cooled gas turbine, with potential for operation at radically increased turbine inlet temper ...

An atmospheric pressure chemical ionization mass spectrometer (APCIMS) will be designed to optimally measure a variety of gaseous species involved in marine boundary layer chemistry and condensation processes. The design of the instrument will modify prior technology, developed at the Geophysics Directorate of the Air Force Phillips Laboratory, to be included in the payload of a remotely piloted, ...

The objectiwe of this proposal is to develop a versatile, inexpensive, and portable spectroscopic probe to quantify the atmospheric corrosion of metal surfaces on aircraft. Since many metals form insoluble salts as products of corrosion reactions, it should be possible to monitor the extent of metal corrosion by measuring the surface coverage of these products. For example, aluminum, which is a ma ...

A radical, high performance system design concept for UAV missions is proposed. Its characteristics derive directly from propulsion and power generation capabilities inherent in microturbine technology under development at MIT. The proposed vehicle configurations is an oblate spheroid, giving a high package volume with sufficient fuel capacity for hover duration of about one hour. Thrust from m ...

Imaging spectrometers are a powerful new tool for performing hyperspectral measurements for remote sensing, environmental monitoring, and target detection and characterization applications. The major problem associated with hyperspectral measurements now, however, is not the technology for performing the measurements but rather the technology for analyzing and recording the high data rates genera ...
