THERE ARE TWO TYPES OF ELECTRONIC COUNTERMEASURE SYSTEMS -ACTIVE AND PASSIVE (ECM). THE PASSIVE ECM USES CHAFF, DECOYS, AND RADAR CROSS-SECTION REDUCTION, AND FOR THE ACTIVE NOISE JAMMERS, AND REPEATER JAMMER. IN THIS PROPOSAL, AN ACTIVE ECM IS PROPOSED WHICH USES A MINIATURE DIGITAL RF MEMORY (DRFM) AS ACTIVE CHAFF IN THE BALLISTIC MISSILE ENVIRONMENT. THIS MINIATURE DRFM UTILIZES STATEOF-THE-ART ...

ALTHOUGH FINITE ELEMENT CODES UTILIZING ELASTIC-PLASTIC-FRACTURING MODELS FOR CONCRETE STRUCTURAL ANALYSIS HAVE BEEN IN USE FOR NEARLY TWO DECADES, SEVERE STRUCTURAL DAMAGE INVOLVING SPALLING AND BREAKUP HAS REMAINED COMPUTATIONALLY INTRACTABLE. THIS PROPOSAL IS AIMED AT THE DEVELOPMENT OF A COMPUTATIONAL CAPABILITY FOR THE ANALYSIS OF REINFORCED CONCRETE STRUCTURES SUBJECTED TO SEVERE STRUCTURAL ...

A REQUIREMENT EXISTS (1) TO DEFINE/ASSESS PHYSICAL SECURITY THREATS TO THE SMALL ICBM HARD MOBILE LAUNCHER (HML) AS POSED BY TERRORIST AND PARAMILITARY GROUPS ADN (2) TO COUNTER AGAINST THESE THREATS. THREAT DEFINITION CHARACTERIZES POTENTIAL THREATS BASED ON A REVIEW OF EXISTING DOCUMENTS WHICH SUMMARIZE PAST TERRORIST ACTIVITY. THREAT CONSIDERATIONS RANGE FROM THEFT TO DESTRUCTION. CHARACTERISTI ...

THE EXCAVATION OF ROCK AND DEEP BASED FACILITIES PRESENTS MAJOR COST AND TECHNICAL CHALLENGES. PROPOSALS FOR TUNNELING ARE MOSTLY BASED ON USING TUNNEL BORING MACHINES. EXCAVATION BY DRILL AND BLAST METHODS, WITH MANY ADVANTAGES, ARE ALSO POSSIBLE. DRILL AND BLAST METHODS ARE LESS SENSITIVE TO ROCK QULITY AND TO CHANGES IN TUNNELING DIRECTION. MANY ATTEMPTS, OVER TIME AND BY DIFFERENT PEOPLE, HAVE ...

ABLATION BEHAVIOR AND THERMAL PROTECTION REQUIREMENTS FOR REENTRY VEHICLES ARE SIGNIFICANTLY INFLUENCED BY ROUGH WALL CONVECTION EFFECTS. TO ACCURATELY CHARACTERIZE THE EFFECTS FOR SYSTEM DESIGN, IT IS ESSENTIAL TO UNDERSTAND THE PHYSICS OF THE TURBULENT BOUNDARY LAYER SUBJECT TO ARBITRARY ROUGHNESSES, AND THE ABLATION INDUCED DEVELOPMENT OF THE MORPHOLOGY. PHASE I OF THIS PROGRAM WILL ADDRESS THE ...

TERRORIST/PARAMILITARY ACTIVITIES ARE ON THE RISE THROUGHOUT THE WORLD. THE IMPLICATION OF THIS ENVIRONMENT FOR THE SMALL ICBM HARD MOBILE LAUNCHER PHYSICAL SECURITY SYSTEM MUST BE CAREFULLY ANALYZED. THIS STUDY WILL DEFINE AND ASSESS POTENTIAL PHYSICAL SECURITY THREATS TO THE SICBM/HML AND WILL DEFINE AND ASSESS COUNTERMEASURE OPTIONS FOR THREAT NEGATION. MASSIVE PROTECTIVE MEASURE, MILITARY ESCO ...
