ALGORITHMS ARE DERIVED THAT DEFINE THE PATHS OF MAXIMUM COHERENCY FOR A SEISMIC EVENT GENERATED BY FIRING AN ARTILLERY WEAPON FROM AN ARBITRARY LOCATION. SIGNAL EXTRACTION TECHNIQUES ARE DESCRIBED TO EXTRACT THE COHERENT SIGNAL FROM AN EVENT RECORDED ON MULTIPLE RECEIVERS. SIMULATED BATTLEFIELD RECORDINGS ARE GENERATED BY TREATING THE SEISMIC SIGNATURE OF ARTILLERY WEAPONS AS IMPULSE RESPONSES FRO ...

THE OBJECTIVE OF THIS TASK IS TO DEFINE ONE OR MORE APSE(S) FOR THE AIRMICS COMMAND BASED ON THE DEVELOPMENT, ENHANCEMENT, AND MAINTENANCECHARACTERISTICS FOR MANAGEMENT INFORMATION SYSTEMS (MISS). APSE(S) WILL BE FORMED FOR THESE THREE MAJOR DOMAINS, WITH EMPHASIS ON LARGE, MEDIUM, AND SMALL SYSTEMS. DURING PHASE I, RESEARCH IS PERFORMED TO IDENTIFY EXISTING CASE TOOLS, ENVIRONMENTS, METHODOLOGIES ...

HF SIGNAL FADING FREQUENTLY RESULTS FROM MUTUALLY INTERFERING MULTIPATH SIGNAL EFFECTS CAUSED BY GROUND OR OCEAN REFLECTION OF THE ELECTROMAGNETIC WAVES ALONG DIVERSE PROPAGATION PATHS. THIS PHASE I SBIR PROGRAM EXPLOITS INNOVATIVE NONLINEAR DYNAMICAL (NDL) SIGNAL PROCESSING METHODOLOGIES TO MODEL, PREDICT AND MINIMIZE THE UNDERLYING ELECTRODYNAMIC SYSTEM PROCESSES, THEREBY REDUCING BACKGROUND NOI ...

A NEW AND INNOVATIVE CLASS OF ADAPTIVE COMPUTATIONAL PROCEDURES IS TO BE DEVELOPED FOR THE SPECIFIC PURPOSE OF NUMERICALLY-MODELING COMPLEX FLOWS INHERENT IN ADVANCED HELICOPTER-BLADE DESIGNS. THESE PROCEDURES MAKE USE OF MATHEMATICALLY CONSISTENT ESTIMATES OF LOCAL NUMERICAL ERROR, AND AUTOMATICALLY REFINE OR UNREFINE THE MESH OR INCREASE OR DECREASE THE LOCAL SPECTRAL ORDER OF THE APPROXIMATION ...

A NEW HIGH-FREQUENCY, NONFOULING, FOUR-ELECTRODE, OPEN-CELL CONDUCTIVITY SENSOR FOR OCEANIC USE IS PROPOSED. THIS SENSOR IS TO REPLACE THE COMMONLY USED CONDUCTIVITY CELL MADE BY N. BROWN INSTRUMENT SYSTEM. THE NEW SENSOR WILL BE DESIGNED TO MINIMIZE OR ELIMINATE PROBLEMS ASSOCIATED WITH N. BROWN CONDUCTIVITY CELL. SOME STRINGENT DESIGN CRITERIA ARE SET FOR THE NEW CONDUCTIVITY SENSOR: 1. THE SENS ...

ADVANCED OPTICAL SYSTEMS PROPOSES TO CONCEPTUALLY DESIGN, EXPERIMENTALLY VALIDATE AND DOCUMENT A MULTI-POINT FIBER-OPTIC NETWORK TO SUPPORT SIMULTANEOUS MULTIPLE RADAR SYSTEM INPUTS. THE PROPOSED NETWORK DESIGN WILL INCLUDE THE NETWORK TOPOLOGY, PROTOCOL STRUCTURE, AND CRITICAL ITEM SPECIFICATIONS NECESSARY TO SUPPORT BEACON/IFF, ANALOG RADAR VIDEO CHANNELS, AND CONTROL INFORMATION OVER THE NETWOR ...
