SENSITIVITY OF STELLAR GUIDANCE OPTICS IS LIMITED BY REFLECTION OF STRAY LIGHT INSIDE THE OPTICAL SYSTEM. IMPROVEMENT BY 50-100% OR MORE CAN BE OBTAINED WITH A BLACK COATING, DISCOVERED BY CHARLES FELDMAN AT JOHNS HOPKINS APPLIED PHYSICS LABROATORY, CONSISTING OF SUBMICROSCOPIC COLUMNS OF AMORPHOUS SILICON PRODUCED BY ETCHING THE SURFACE OF A SOLID SILICON LAYER. THE PROGRAM, WITH DR. FELDMAN AS C ...

TAC PROPOSES TO CONDUCT A STUDY TO EVALUATE THE COMPARATIVE EFFECTIVENESS OF VARIOUS FORWARD-LOOKING AUTONOMOUS SENSORS AND ALGORITHMS FOR TLAM-C. THE CURRENT TLAM-C USES A TERRAIN MAPPING RADAR ALTIMETER AND CORRELATES THE SENSED AREA AT KEY WAYPOINTS WITH A STORED DIGITAL REPRESENTATION OF THE TERRAIN AREA AT THE WAYPOINTS TO PROVIDE MID-COURSE AND TERMINAL GUIDANCE CORRECTION TO THE INERTIAL NA ...

THE MARINE CORPS TRAINS ITS COMMANDERS AND THEIR STAFFS UNDER A NUMBER OF CONSTRAINTS (TIME, MONEY, TRAINING AREAS, ETC.) NEW C3I SYSTEMS AND WEAPON SYSTEMS REQUIRE MORE TRAINING THAN EVER BEFORE. ONE INNOVATIVE TOOL THE MARINE CORPS HAS DEVELOPED IS THE TACTICAL WARFARE SIMULATION EVALUATION AND ANALYSIS SYSTEM (TWSEAS) IT IS, HOWEVER, BECOMING OBSOLETE AND ITS REPLACEMENT WILL REQUIRE CAREFUL AN ...

A SONOBUOY ON THE BOTTOM OF THE OCEAN CAN ACHIEVE LONG DETECTION RANGES BY USE OF THE RELIABLE ACOUSTIC PATH (RAP). BY PUTTING AN ACOUSTIC SIGNAL PROCESSOR IN THE BUOY TO DO SPECTRUM ANALYSIS AND CONTACT REPORT GENERATION, THE DATA TRANSMITTED TO SURVEILLANCE AIRCRAFT CAN BE REDUCED TO SHORT BURSTS ON A SCHEDULE THAT MEETS PATROL AIRCRAFT REVISIT REQUIREMENTS FOR INCREASED AIRCRAFT UTILIZATION AT ...

A DIGITAL ENCODING SCHEME FOR THE ARCHIVAL, STORAGE, AND SUBSEQUENT TRANSMISSION OF COLOR GRAPHIC IMAGES WILL BE DEVELOPED. THIS SCHEME WILL ACCOMMODATE RAPID RESPONSE TIMES AND ALLOW FOR FUTURE IMPROVEMENTS AND MODIFICATIONS IN A WELL-DEFINED AND ECONOMIC MANNER. THE TECHNIQUE PROPOSED TO ACCOMPLISH THIS TASK IS BASED ON A PICTURE MATRIX TRANSFORMATION, WHICH IS BASED ON THE S-TRANSFORM CODING SC ...

THIS PROPOSAL PRESENTS AN APPROACH FOR ASSESSING THE FEASIBILITY OF MEASURING AIRCRAFT AND/OR SHIP USER VEHICLE HEADING AND ATTITUDE AND DETERMINING WHETHER +/1 ACCURACY CAN BE OBTAINED USING THE GLOBAL POSITIONING SYSTEM (GPS). THE TECHNICAL APPROACH PROPOSED WILL EXAMINE THE NAVIGATION SIGNALS AND THE METHODS OF PROCESSING THE INFORMATION, AND WILL PROPOSE METHODS FOR EXTRACTING HEADING AND ATTI ...
