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 ...

LONG WAVELENGTH GROUND-BASED MULTISTATIC RADAR SYSTEMS WHICH MAY BE IN THE HF, VHF, OR UHF BANDS OFFER POTENTIAL SOLUTIONS TO THE PROBLEMS ASSOCIATED WITH PERFORMING THE TACTICAL ARMY MISSION OF FOREWARD AREA AIR DEFENSE (FAAD) AND WEAPONS LOCATION WITH MONOSTATIC SHORT WAVELENGTH RADARS. HOWEVER, SIGNIFICANT PROBLEMS ARE ALSO INTRODUCED WITH THE USE OF THESE LONG WAVELENGTH BISTATIC RADAR SYSTEMS ...

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 ...

THE PROJECT WILL DEVELOP A NOVEL MINIATURE PULSE WIDTH MODULATED POWER DRIVER FOR ACTUATORS, I.E. DC MOTOR. THE POWER DRIVER WILL DELIVER 50 AT 50VDO IN A DOUBLE INON PACKAGE. THIS COMPACT DESIGN CAN ONLY BE ACHIEVED THROUGH THE INNOVATIVE COMBINATION OF MODER POWER SEMICONDUCTOR TECHNOLOGIES, PROPRIETORY CIRCUIT DESIGN, AND STATE-OF-THE-ART PACKAGING TECHNOLOGY WHICH UTILIZES NEW HEAT CONDUCTIVE ...

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 ...
