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 ...

THIS EFFORT WILL ASSESS THE TECHNICAL STATE OF THE ART FOR MODELBASED VISION APPROACHES TO ANALYZING RADAR AND OTHER ACTIVE SENSOR IMAGERY. MODEL-BASED APPROACHES RELY HEAVILY ON USING SEMANTIC MODELS TO PREDICT IMAGE OBJECTS AND FEATURES IN A MANNER THAT FACILITATES RECOGNITION OF THE OBJECT IN THE IMAGE. TO DATE, RESEARCH IN THIS AREA HAS FOCUSED PREDOMINATELY ON OPTICAL IMAGERY. THE STUDY WILL ...

THE OBJECTIVE OF THIS EFFORT IS TO EXPLORE THE POTENTIAL OF FINITE INDUCTIVE SEQUENCE PROCESSING (FISP) (A PROPRIETARY PROCESSING TECHNIQUE OWNED JOINTLY BY ADS AND CIS) TO PROVIDE AUTOMATED DECISIONS AND CONTROL REQUIRED TO EFFECT OPTIMUM EMPLOYMENT OF AIRCRAFT ONBOARD COMMUNICATIONS IN THE YEAR 2000 AND BEYOND. FISP IS AN ALGORITHMIC APPROACH TO A KNOWLEDGE BASED ARTIFICIAL INTELLIGENCE (AI) SYS ...

INNOVATIVE TECHNICAL APPROACHES FOR DETECTING AND CHARACTERIZING BULK DEFECTS IN LARGE AEROSPACE STRUCTURES ARE URGENTLY NEEDED. THE INTEGRITY OF BONDED SURFACES IN THE Y-JOINT AND RESTRICTER REGIONS OF LARGE SOLID BOOSTERS, SUCH AS TITAN 34D MOTORS, IS A GOOD EXAMPLE OF A CRITICAL APPLICATION WITHOUT A DEPENDABLE INSPECTION METHOD. IN FULLY ASSEMBLED T34D MOTORS, THESE ZONES, WHICH ARE THE MOST C ...

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 ...
