AN ADAPTIVE ARRAY SIGNAL PROCESSOR CAPABLE OF ADAPTIVELY NULLING MULTIPE SIDELOBE JAMMERS AND SIDELOBE DISTRIBUTED AND DISCRETE GROUND CLUTTER RETURNES COMPETING WITH THE TARGET RETURN, IN AI-LOW OBSERVABLE TARGET DETECTING MEDIUM-PRF RADARS IS THE SUBJECT OF A DESIGN STUDY. THE ASI-DEVELOPED AIRBORNE RADAR ADAPTIVE ARRAY SIMULATION TEST BED (IMPLEMENTED IN A PC-286 COMPUTER) IS PROPOSED TO BE USE ...

MONOSTATIC RADAR SYSTEMS USING SPACE-TIME ADAPTIVE PROCESING (STAP) HAVE BEEN SIMULATED IN DETAIL AND SHOWN TO PROVIDE LARGE IMPROVEMENTS IN MOVING TARGET DETECTION. AND TRACKING CAPABILITY. THE PROPOSED STUDY WILL APPLY STAP TECHNOLOGY TO BISTATIC RADARS WITH AIRBORNE RECEIVERS AND AIRBORNE OR STATIONARY TRANSMITTERS. CANCELLATION OF CLUTTER IN A BISTATIC RADAR IS COMPLICATED BY THE RAPIDLY VARYI ...

Recent advances enable thermionic converters to achieve energy conversion efficiencies of up to 30%. Advanced Energy Technology will explore this technology for nuclear space power. High efficiency means that more power can be obtained with a smaller system radiator; this reduces spacecraft mass and increases manueverability, as well as improved packaging. Our converter is inherently survivable ag ...

Phase I will analyze use of a hypervelocity launcher to provide ahigh mass (2 to 20 kilograms), hypervelocity (4 km\sec) demonstrator for a Theater Missile Defense (TMD) System. Current ballistic powder guns, along with one and two stage light gas guns, cannot meet the high mass requirements while maintaining high velocities required for rapid target aquisition. A concept that would provide low co ...

THE PRESENT WORK DEALS WITH THE DESIGN, DEVELOPMENT, TESTING AND IMPLE MENTATION OF A REAL-TIME MONITORING SYSTEM TO DETERMINE THE PARTICLE S IZE DISTRIBUTION OF SOOT. THE NOVEL TECHNIQUE SHALL MAKE USE OF MULTI WAVELENGTH ANALYSIS OF THE LIGHT SCATTERING PROPERTIES OF THE PARTICLE S TO INFER THE PARTICLE INDEX OF REFRACTION, THE SOOT NUMBER DENSITY A ND THE PARTICLE SIZE DISTRIBUTION. THE PHASE I ...

AEROBALLISTIC RANGES PROVIDE INVALUABLE DATA FOR DESIGNING AIR DELIVERABLE MUNITIONS AND ARMAMENT. PRESENT METHODS FOR OBTAINING AERODYNAMIC COEFFICIENTS FOR THESE MUNITIONS ARE CUMBERSOME AND TIME CONSUMING. DATA REDUCTION INVOLVES A LONG SEQUENCE OF INDIVIDUAL STEPS WHICH CAN TAKE FROM SEVERAL DAYS TO WEEKS. BECAUSE OF THE SLOW TURN AROUND TIME, ERRORS ARE NOT CORRECTED DURING THE TEST. THE INEX ...

AETECH WILL PRODUCE AN AUTOMATED TOOL TO ASSIST IN THE DESIGN AND DEVE LOPMENT OF COURSEWARE FOR INTELLIGENT COMPUTER ASSISTED INSTRUCTION SYSTEMS USING ENHANCED HUMAN-COMPUTER INTERFACES. THE AUTOMATED TOOL, CALLED THE INTELLIGENT COURSEWARE DEVELOPER, WILL USE APPROVED AIR FORCE METHODS OF INSTRUCTIONAL SYSTEM DEVELOPMENT (ISD) TO ALLOW THE AIR FORCE INSTRUCTIONAL DESIGNER TO BUILD A COURSE USIN ...
