MICROWAVE RADIO CORPORATION PROPOSES TO PERFORM ADEQUATE STUDY AND TESTING TO SPECIFY A FORM, FIT, AND FUNCTIONAL REPLACEMENT FOR THE TWT AMPLIFIER IN THE AN/FRC-173(V) DRAMA RADIO.

THIS COMBINED THEORETICAL AND EXPERIMENTAL PROGRAM WILL INVESTIGATE GENERATION OF ACOUSTIC SIGNALS WITH A CO2 LASER. ACOUSTIC SIGNAL GENERATION HAS BEEN DEMONSTRATED AND THIS PROGRAM WILL PROVIDE THE RELATIONSHIP BETWEEN LASER PARAMETERS AND ACOUSTIC PARAMETERS FOR THE EXPERIMENTALLY USED SEA ICE THICKNESS OF APPROXIMATELY 30 CENTIMETERS. THE EXPERIMENTS WILL BE PERFORMED IN THE ONLY COMMERCIALLY ...

VIBRATION MONITORING R&D HAS BEEN SIGNAL PROCESSING ORIENTED AND PROBLEMS ARISE BECAUSE TECHNIQUES DEVELOPED FOR ONE MACHINE ARE NOT TRANSFERABLE TO OTHERS. TIDG PROPOSES A UNIFIED APPROACH TO MONITORING R&D WHICH WILL USE MODELING AND DATA TO PREDICT FAULT SIGNATURES, USE CEPSTRAL AND OTHER FORMS OF PROCESSING TO REMOVE OR DEFINE THE MACHINE'S STRUCTURAL RESPONSE TO THE DEFECT, AND USE UNIQUE SEN ...

THE NAVY CURRENTLY USES AQUEOUS ELECTROLYTE-BASED MG PRIMARY BATTERIES IN A VARIETY OF WEAPONS SYSTEMS. OWING TO PARASITIC MG/H(2)O CORROSION REACTIONS, DELIVERABLE VOLTAGES AND ENERGY DENSITIES ARE SUBSTANTIALLY LESS THAN THEORETICAL. MOREOVER, VOLTAGE DELAYS OFTEN COMPROMISE PERFORMANCE AND THEEBY APPLICABILITY. THUS THERE IS A NEED FOR NEW NON-AQUEOUS ELECTROLYTES COMPATIBLE WITH MG BATTERY CHE ...

THE PROBLEM OF ESTIMATING RADAR TARGET PARAMETERS SUCH AS SHAPE, SIZE AND MATERIAL PROPERTIES FROM MONOSTATIC SCATTERING MEASUREMENTS IS FORMULATED WITHIN THE CONTEXT OF STATISTICAL ESTIMATION THEORY AND INVERSE SCATTERING. A BAYESIAN APPROACH TO THIS PROBLEM IS PROPOSED WHERE THE LIKLIHOOD RATIOS BETWEEN MULTIPLE TARGET HYPOTHESES ARE USED TO MAKE AN OPTIMUM TARGET IDENTIFICATION FROM SPARSE SCAT ...

THE NAVY IS CURRENTLY DEVELOPING A PASSIVE INFRARED SYSTEM FOR FLEET DEFENSE TO DETECT AIRBORNE TARGETS AGAINST A CLUTTER BACKGROUND. THE BACKGROUND MEASUREMENT AND ANALYSIS PROGRAM (BMAP) IS SUPPORTING THIS EFFORT IN THE ACQUISITION AND ANALYSIS OF ARCHIVAL QUALITY IMAGERY DATA OF CLOUD AND SEA CLUTTER BACKGROUNDS. THE PROPOSED PROGRAM WILL PROVIDE BMAP WITH THE OVERALL ARCHITECTURE AND MODULES F ...

A NOVEL APPROACH TO THE SAFETY OF RESERVE BATTERIES IS TAKEN, BASED ON A BATTERY DESIGN THAT ELIMINATES THE USE OF A SEPARATE RESERVOIR TO STORE THE ELECTROLYTE DURING INACTIVE LIFE OF THE BATTERY. CELLS WITHOUT THE ELECTROLYTE AND THE ELECTROLYTE ITSELF ARE SITUATED IN A BATTERY CONTAINER, STORED UNDER VACUUM. THE BATTERY IS ACTIVATED SIMPLY BY ADMITTING THE AIR INTO THE CONTAINER. THE AIR FORCES ...

THERMALLY ACTIVATED LITHIUM ALLOY - IRON PYRITE BATTERIES ARE USED IN A VARIETY OF MILITARY APPLICATIONS. THESE BATTERIES EXHIBIT ABNORMALLY HIGH VOLTAGES DURING THE FIRST SEVERAL MINUTES OF DISCHARGE. THE VOLTAGE TRANSIENT HAS BEEN ASSOCIATED WITH THE PHYSICAL AND CHEMICAL PROPERTIES OF THE NATURALLY OCCURRING PYRITE USED IN THE CATHODE. THIS PROGRAM SEEKS TO DEMONSTRATE THAT HIGH PURITY SYNTHETI ...

THE STRUCTURAL INTEGRITY OF GRAPHITE-EPOXY COMPOSITES CAN BE VALIDATED BY MEASUREMENT OF EDDY-CURRENTS INDUCED IN ELECTRICALLY CONDUCTING FIBERS. EDDY-CURRENTS ARE DIMISHED IN DAMAGE REGIONS OF A COMPOSITE STRUCTURE BECAUSE RUPUTRED FIBERS DO NOT PROVIDE AN ELECTRICALLY CONDUCTING PATH. THE PROGRAM PROPOSED HEREIN SEEKS SOLUTIONS TO PRACTICAL PROBLEMS AND OBSTACLES TO THE REALIZATION OF A PRACTICA ...
