PHASE I PROPOSES TO GATHER THE DATA AND DISCRIPTIVE INFORMATION FOR A 28-SHOT SET OF EXPERIMENTS MADE IN THE EARLY 1970'S TO MEASURE HIGH OVERPRESSURE AIRBLAST FROM 8-LB CHARGES OF PBX-9404, TO PREPARE A WORK PLAN AND PROCEDURES FOR COMPLETING THE DATA PROCESSING FROM THE EXPERIMENTS, CHECKOUT THE PROCEDURES WITH SAMPLE ANALYSES, AND TO PREPARE A COST ESTIMATE FOR PHASE II. THE COMPLETION OF PHASE ...

A PHASE I SBIR STUDY IS PROPOSED TO DETERMINE ANALYTICALLY THE FEASIBILITY OF MEASURING THE FREE-AIR (UNREFLECTED) AIRBLAST WAVEFORMS FROM A NUCLEAR BURST IN AN UNDERGROUND CAVITY. SUCH DATA WOULD BE USEFUL FOR EVALUATING MEASUREMENTS TO BE MADE OF THE AIRBLAST IN THE REGION OF BLAST RELECTION FROM THE CAVITY FLOOR AND WALL. THE STUDY WILL CONSIDER WELL-PROVEN PIEZOELECTRIC AND RESISTIVE TECHNIQUE ...

VOLUMETRIC INTERPRETATION OF MULTI-SPECTRAL SENSOR DATA AS WELL AS OTHER IMAGE ANALYSIS TASKS INVARIABLY INVOLVE A SEGMENTATION PREPROCESSING STEP. THE AIM OF THIS PROPOSAL IS TO IMPLEMENT A FAST (REAL-TIME) AND UNIVERSAL SEGMENTATION ALGORITHM FOR MULTI-SENSOR AND MULTISCALE IMAGE DATA. THE PROPERTIES OF THIS ALGORITHM ARE THE FOLLOWING. IT IS MULTISCALE AND PYRAMIDAL. IN OTHER WORDS, IT WILL NOT ...

A NEW ADVANCED MANPACK RADIO CONCEPT FOR UHF DAMA SATELLITE COMMUNICATIONS IS PROPOESD FOR DATA AND VOICE COMMUNICATIONS. THE PROPOSED RADIO CONCEPT UTILIZES A NEW MULTI-CHANNEL DAMA APPROACH IN ORDER TO ACHIEVE INTER-SERVICE SATELLITE RESOURCE SHARING ON A PRIORITY BASIS AND INCREASED USER CONNECTIVITY WHILE MAINTAINING INTEROPERABILITY WITH EXISTING DAMA SYSTEMS SUCH AS USTS AND MINIDAMA.

REPORTS ON ACCIDENTS OF MODERN MILITARY FIGHTERS INCREASINGLY IMPLICATE PILOT DISORIENTATION AS A FACTOR. WHILE SPATIAL DISORIENTATION OF PILOTS HAS BEEN A PROBLEM IN AVIATION SINCE THE BEGINNINGS OF INSTRUMENT FLIGHT, IT HAS BEEN A GROWING CONCERN IN HIGH PERFORMANCE JET COCKPITS. THE HEAD-UP DISPLAY (HUD) HAS BEEN IMPLICATED AS A CONTRIBUTOR TO DISORIENTATION. RECENT RESEARCH HAS DEVELOPED SEVER ...

THE OVERALL OBJECTIVE OF THIS RESEARCH IS TO DETERMINE THE FEASIBILITY AND PERFORMANCE OF ALUMINUM-MATRIX COMPOSITES REINFORCED BY DIAMOND OR DIAMOND/ BERYLLIUM ELEMENTS FOR AIRCRAFT POWER COMPONENTS. IT IS EXPECTED THAT SELECTED SAMPLES WILL EXHIBIT TENSILE STRENGTH, THERMAL COEFFICIENT OF EXPANSION (TCE), AND YOUNG'S MODULUS SUPERIOR TO THAT OF ANY EXISTING TRADITIONAL METAL OR ALUMINUMBASED MET ...

SIMULATING THE WEIGHTLESS CONDITION OF ORBIT IN GROUND-BASED BEAM POINTING AND TRACKING EXPERIMENTS REQUIRES A MEANS FOR OFFLOADING THE WEIGHT OF THE BEAM DIRECTOR FROM THE SERVO SYSTEM THAT CONTROLS ITS POSITION AND ORIENTATION. A SUSPENSION SYSTEM MUST SUPPORT THE BEAM DIRECTOR WITH ONLY MODEST STATIC DEFLECTION UNDER ITS WEIGHT AND WITH MINIMAL CONSTRAINT FORCES DUE TO SUSPENSION STIFFNESS, MAS ...

THIS PROPOSAL DESCRIBES AN INNOVATIVE TECHNICAL APPROACH FOR DVELOPING TRANSPORTABLE AND RAPIDLY DEPLOYABLE VLF.LF ANTENNAS, CAPABLE OF SUPPORTING THE FULL RANGE OF 616-A OPERATING MODES. OUR BASIC DESIGN CONECPT INVOLVES THE USE OF FAST-WAVE TECHNIQUES, IN WHICH SERIES CAPACITORS ARE USED TO DRAMTICALLY INCREASE THE RADIATING EFFICIENCY OF SIMPLE, ON SURFACE WIRE ANTENNAS; OTHER DETAILED DESIGN O ...
