THE GOAL OF THE OVERALL PROGRAM IS TO INVESTIGATE THE RELEVANT INFORMATION CONTENT CONTAINED IN A PHYSIOLOGICALLY BASED MODEL OF THE HUMAN VISUAL SYSTEM WITH REGARDS TO THE EFFICIENT AND EFFICACIOUS EXTRACTION OF DEPTH THROUGH STEREOPSIS. IN THE CONTEXT OF A MODEL OF THE HUMAN VISUAL SYSTEM THIS APPROACH UTILIZES THE PHYSIOLOGICAL INFORMATION FILTERING CHARACTERISTICS KNOWN TO EXIST IN PRIMATE VIS ...

THE PROPOSED RESEARCH WILL EXAMINE THE ANTI-SIMULATION TACTIC BOTH FROM THE STANDPOINT OF THE OFFENSE AND FROM THAT OF THE DEFENSE. THE OFFENSE POINT OF VIEW INCLUDES DETERMINING THE SIGNATURE FEATURES THAT THE ANTI-SIMULATION TACTIC ATTEMPTS TO DISGUISE AND THE DEGREE TO WHICH THESE FEATURES CAN BE MODIFIED BY PRACTICAL ALTERATIONS OF BOTH THE RV AND THE DECOY. THIS PORTION OF THE RESEARCH WILL A ...

THE EFFORT OBJECTIVE IS TO DEVELOP AN INTERACTIVE MODEL TO DETERMINE SPACE SYSTEMS SUPPORT REQUIREMENTS, ENABLE SYSTEM OPERATING VULNERABILITY AND COST DRIVER ASSESSMENTS, AND FACILITATE TRADE STUDIES. THE CONCEPT FOR THE INTERACTIVE DATA BASE IS TO TIE AN ESTABLISHED EXPERT SYSTEM SHELL WITH AN EXISTING DATA BASE SHELL THAT WILL ACCOMMODATE INTERACTIVE PROCESSING WITH OTHER ALGORITHM MODULES DEDI ...

DESIGN CONSTRAINTS ON WINDOWS FOR ELECTRO-OPTICAL (EO) SENSORS ABOARD HYPERVELICITY PLATFORMS WILL BE ESTABLISHED. THESE CONSTRAINTS ARE BASED ON THE WAY SENSING OF INFRARED (IR) AND VISIBLE RADIATION ARE AFFECTED BY: (1) NEAR-WINDOW TURBULENCE, (2) IR WINDOW EMISSION INDUCED BY AERODYNAMIC HEATING, (3) DISTORTION INTRODUCED BY WINDOW CURVATURE, (4) SCATTERING AND EMISSION FROM ABLATING MATERIALS, ...

A METHODOLOGY/MODEL FOR THE CALCULATION OF LETHALITY EFFECTIVENESS EQUIVALENCY RELATIONSHIPS FOR AN EVALUATION SET OF SPECIFIC TACTICAL NUCLEAR, CONVENTIONAL UNITARY, AND ICM WEAPONS WILL BE DEVELOPED. THE APPROACH WILL CONSIST OF SPECIFIC MODIFICATIONS TO AN EXISTING COMPUTER SIMULATION MODEL, THE NICHOLS RESEARCH CORPORATION WEAPONS EFFECTIVENESS SIMULATION (WES) MODEL, WHICH WILL UTILIZE INPUTS ...

INCOMPLETE BUT SUBSTANTIAL RESULTS INDICATE THE SUCCESSFUL FORMULATION OF A GROUP OF COMPOSITE ADVANCED HALONS (CAH) DESIGNED TO COUPLE THE HIGHEST POSSIBLE SAFETY IN USE WITH EFFICIENCY IN OPERATION. THE CAH WOULD UTILIZE WATER OR A PROPRIETARY CARRIER AND/OR ADDITIVES WHICH ENABLE THE HALON LIQUID TO BE CONTAINED AT LOW PRESSURE AND TO HAVE A RELATIVELY HIGH BOILING POINT. THESE PHYSICAL CHARACT ...

THE HIGH PERFORMANCE POTENTIAL OF COMPOSITE PROPULSION SYSTEMS MAKE THEM ATTRACTIVE FOR WINGED HORIZONTAL TAKE-OFF BOOSTER AND SINGLE STAGE TO ORBIT LAUNCH VEHICLES. NUMEROUS TYPES OF SYSTEMS HAVE BEEN PROPOSED, RESEARCHED, ANALYZED, AND TESTED. THE OVERALL OBJECTIVE OF THIS EFFORT IS A CRITICAL EXAMINATION OF PAST STUDIES AND ANALYSES TO IDENTIFY PROMISING CONCEPTS FOR TECHNOLOGY DEVELOPMENT FOR ...

THE OBJECTIVE OF THIS RESEARCH IS TO INVESTIGATE MEANS OF IMPROVING RADIO RECEPTION AND THE QUALITY OF DEMODULATED INFORMATION BY INCORPORATING WARENESS OF THE ELECTRO-MAGNETIC ENVIRONMENT IN COMMUNICATIONS RECEIVERS. EMPHASIS IS PLACED ON THE INTEGRATED USE OF EXPERT SYSTEMS AND ADAPTIVE SIGNAL PROCESSING TECHNIQUES. ADAPTIVE TECHNIQUES PERMIT RECEIVER SUBSYSTEMS TO SENSE THE RECEIVED SIGNAL AND ...

THE OBJECTIVE OF THIS RESEARCH IS TO INVESTIGATE NEW AUTOMATED METHODS OF SENSING, PLANNING, AND CONTROLLING THE USE OF RADIO FREQUENCY COMMUNICATIONS PARAMETERS OF SOPHISTICATED MILITARY AIRCRAT AT THE AIRCRAFT PLATFORM AND DATA LINK LEVELS, TO MAXIMIZE THE OVERALL QUALITY AND RELIABILITY OF THE INFORMATION TRANSMITTED AND RECEIVED. EMPHASIS IS PLACED ON METHODOLOGIES AND MEASUREMENT CRITERIA FOR ...
