The overall abjective of this proposed project is the development of detailed definitions for the interfaces defined by the ABBET architecture. Signal models wil developed based upon the C/ATLAS set of signal nouns. A Test Foundation Framework (TFF) will be implemented to demonstrate the ability of test program or test program component transfer across multiple test platforms. This phase also w ...

SIGNIFICANT NUMERICAL COMPUTATIONS NOW COMMONLY REQUIRE VASTPROCESSING POWER. AT THE CORE OF MANY OF THESE PROBLEMS IS THE SOLUTION OF LARGE, SPARSE SYSTEMS OF EQUATIONS. A HOST OF SPECIALIZED HIGH-SPEED PROCESSORS HAVE BEEN DEVELOPED TO ATTACK LARGE PROBLEMS. SYSTOLIC ARCHITECTURES HAVE PROVEN TO BE EXCELLENT CANDIDATES FOR A RANGE OF TASKS, AND THEY PROMISE TO CONTINUE AS POWERFUL COMPUTING TOOL ...

The detection of low velocity targets by a high PRF surveillance radar such as the E-3 AWASCS is exacerbated by the two different clutter return phenomena: the J-Hook return and the Horseshoe return. The J-Hook return is observed primarily when the antenna points downward. In these geometries the clutter screen below the antenna may not adequately suppress the elevation sidelobe return, which ...

IN THE PAST DECADE, STUDIES HAVE INDICATED THAT IT IS THEORETICALLY POSSIBLE, IN A SINGLE OPTO-COUPLED SOLID STATE DEVICE, TO SWITCH HIGH VOLTAGES (100 KV/CM LENGTH) AND HIGH CURRENTS (10KA/CM WIDTH) WITH PHENOMENALLY FAST RURN-ON/TURN-OFF TIMES, MORE EFFICIENTLY AND COMPACTLY THAN USING EXISTING THERMIONIC OR PLASMA DEVICES. THE MOST HEAVILY STUDIED PHOTOCONDUCTORS FOR SWITCHING APPLICATIONS HAVE ...
