SINCE 1975, THE USAF HAS DEVELOPED THROUGH ITS FUZING BRANCH, EGLIN AFB, A NEW CLASS OF PROXIMITY DETECTORS KNOWN AS BASEBAND REFLECTOMETER (BAR) SYSTEMS. IN ADDITION TO HAVING EXCELLENT RESOLUTION (E.G.LESS THAN A FOOT), BAR SYSTEMS HAVE BEEN MADE IMMUNE TO MANY FORMS OF JAMMING AND HAVE BEEN USED AS ALTIMETERS IN TARGET ACTIVATED MUNITIONS(TAM) APPLICATIONS AS WELL AS SENSORS FOR PROXIMITY FUZES ...

A FIBER OPTIC PRESSURE SENSOR BASED ON THE PHOTOELASTIC EFFECT IS DISCUSSED. DUE TO INTRINSIC IMMUNITY TO ELECTROMAGNETIC INTERFERENCE,THE FIBER OPTIC SENSOR OFFERS THE PROMISE OF FUNDAMENTAL IMPROVEMENT RELIABILITY. A POLARIMETRIC SENSING TECHNIQUE MINIMIZES THE EFFECTS OF RADIATION DAMAGE TO FIBERS. THE SENSOR EXPLOITS THE CHANGES IN INDEX OF REFRACTION PRODUCED BY STRESS IN PHOTOELASTIC MATERIA ...

THIS PROJECT WILL PRODUCE THE RESULTS NECESSARY TO DETERMINE IF ULTRHIGH TEMPERATURE FUELS PRODUCE FLAMES WITH SUFFICIENT EMISSIVITY TO BE CONSIDERED AS A CANDIDATE FOR THE DNA THERMAL RADIATION SOURCE TEST FACILITY. A SMALL TORCH WILL BE CONSTRUCTED WHICH WILL BURN COMMERCIALLY AVAILABLE CHEMICALS SIMILAR TO ULTRA-HIGH TEMPERATURE FUELS OF THE CMNN CLASS. THERMAL FLUX AND SPECTRAL MEASUREMENTS OF ...

A LASER MICROPROBE FOR ANALYZING LASER PRODUCED MATERIAL BLOWOFF FROM BULK MATERIALS IS TO BE DEVELOPED. MOST WORK ON LASER-TARGET AND LASER-SURFACE INTERACTIONS HAS CONCENTRATED ON THE DEVELOPMENT OF DIAGNOSTICS AND PROBES FOR MEASURING PHYSICAL PROPERTIES OF THE PLASMA PRODUCED FROM PELLETS, THIN FILM TARGETS, AND BULK MATERIALS. LITTLE WORK HAS BEEN DONE TO ANALYZE THE MATERIAL BLOWOFF. WE SHAL ...

INVESTIGATE POTENTIAL OF A NOVEL CONCEPT TO GENERATE SPECIFIC WAVELENGTH REGIONS OF HIGH INTENSITY RADIATION AND/OR PLANAR BLAST WAVES TO PRODUCE, ON CLOSE-BY (TARGET) STRUCTURES AND/OR MATERIALS, THE THERMAL AND/OR SHOCK LOADINGS DELIVERED BY SINGLE PULSE OR REPETITIVE PULSE LASERS. THE CONCEPT, IF SUCCESSFUL, COULD APPLY OVER LARGE (ONE FOOT OR MORE) DIAMETER AREAS ON LARGE, SCALABLE STRUCTURES/ ...

ADVANCED SURVEILLANCE SYSTEMS WILL BE REQUIRED TO OPERATE IN A TRANS-ATTACK AND POST-ATTACK ENVIRONMENT. THE HIGH ALTITUDE CLUTTER FOR SUCH AN ENVIRONMENT IS NOT ACCURATELY CHARACTERIZED. THE PROPOSED OPTICAL TECHNIQUE PROVIDES A REAL-TIME ADAPTIVE CAPABILITY TO REJECT NUCLEAR CLUTTER AND OPTIMIZE SYSTEM PERFORMANCE. THIS TECHNIQUE UTILIZES A DUAL-STATE OPTICAL SYSTEM WHOSE IMAGING PROPERTIES ALTE ...

INTERMEDIATE ALTITUDE (\50-100 KM) NUCLEAR EVENTS PRODUCE A STRONG SHOCK. THE MATERIAL HEATED BY THIS SHOCK RADIATES IN MANY IR MOLECULAR BANDS. ACCURATE MODELING OF THE IR EMISSION IS POSSIBLE ONLY IF THE GAS STRUCTURE NEAR THE SHOCK CAN BE DETERMINED. A NUMERICAL HYDRODYNAMICS CODE THAT USES A DYNAMICAL ADAPTIVE GRID (DAG) CAN GIVE HIGH SPATIAL RESOLUTION NEAR THE SHOCK WHILE THE SHOCK PROPAGATE ...
