THE DEVELOPMENT OF SIMULATION MODELS OF A DISTRIBUTED SYSTEMS AND THEIR MAPPING INTO A PARALLEL SYSTEM, IS A HIGHLY COMPLEX TECHNICAL TASK BECAUSE OF THE GREAT INFLUENCE ITS VARIOUS ELEMENTS WILL HAVE ON ITS PERFORMANCE. THERE ARE MAJOR TECHNICAL ISSUES INVOLVED IN PERFORMING SUCH COMPLEX SIMULATION EFFORT, INCLUDING UNIQUE REQUIREMENTS SIMULATION MODELS, VARIED ARCHITECTURAL CONCEPTS OF DISTRIBUT ...

A PORTABLE, LOW COST FM-CW DOPPLER WEATHER RADAR IS PROPOSED TO PROVIDE "REAL-TIME" METEOROLOGICAL DATA IN THE FIELD. SUCH A SYSTEM WOULD ASSIST BATTLEFIELD DECISION MAKING BY MONITORING CONDITIONS PERTINENT TO MICROWAVE DUCTING, ARTILLERY CONTROL, AND DETERMINING LOCAL WEATHER. CURRENT DOPPLER WEATHER RADARS TEND TO BE PULSED, VERY LARGE, AND TO COST MILLIONS OF DOLLARS; THEY REQUIRE A LARGE OPER ...

The Abrams turbine engine (AGT-1500) is currently suffering from an issue in which the compressor stalls, creating a surge event that causes significant damage to the fourth stage of the low pressure compressor There is a need for a viable system for measuring the early onset or precursors of rotating stall in real-time on an operational turbine engine, which can detect a surge event in order to t ...

THE CONCEPT FOR AN AUTONOMOUS, DISTRIBUTED RF POWER MONITOR SYSTEM IS DESCRIBED. THE SYSTEM IS CAPABLE OF MONITORING RF POWER LEVELS OVER A FREQUENCY RANGE OF 300 KHZ TO 100 GHZ. AUTOMATIC OPERATION AND HARDWARE REDUNDANCY ENABLE THE SYSTEM TO CONTINUE OPERATION EVEN IF SOME ELEMENTS FAIL OR ARE REMOVED FOR MAINTENANCE. THE SYSTEM CONCEPT IS ADAPABLE TO REMOTE AREAS AND REQUIRES NO DEDICATED POWER ...

AN INNOVATIVE CONCEPT FOR A NEW CLASS OF EMP SIMULATORS IS PROPOSED. THE ELECTROMAGNETIC EQUIVALENCE PRINCIPLE IS APPLIED TO PROVIDE A THREAT LEVEL SIMULATION WITH A BANDWIDTH GOAL OF 1 GHZ AND ARBITRARY ANGLES OF INCIDENCE AND POLARIZATION ARE PROVIDED BY SOFTWARE. IT IS ENVIRONMENTALLY SOUND AND IS HIGHLY AUTOMATED. IT IS EXPECTED TO BE LESS EXPENSIVE TO PROCURE AND MAINTAIN THAN CONVENTIONAL ME ...

There is a continuing push for very large format, very high dynamic range, very fast frame rate digital Infrared Focal Plane Arrays (IRFPAs) by the DOD community. Some emerging applications require FPA data rates >100 Gb/s; for commonly used Low Voltage Differential Signal (LVDS) output circuits with 1 Gb/s capability, this translates to 100 pairs of Dewar feedthrough wires creating un-manageable ...
