INNOVATIVE TECHNIQUES ARE PROPOSED FOR INVESTIGATION IN A PHASE I EFFORT TO DETERMINE PASSIVE RF SURVEILLANCE AND TARGETING SENSORS AND ASSOCAITED METHODOLOGY FOR PERFORMING RAPID AND ACCURAGE MEASUREMENTS OF RANGE/LOCATION OF THREAT RF EMITTERS. THE ESSENTIAL PHYSICAL CONSTRAINTS TO BE OBSERVED ARE SENSOR COMPATIBILITY WITH, AND PORTABILITY OF THE ASSOCIATED RANGE DETERMINATION/PROCESSING EQUIPME ...

HALON 1301 (CF3BR) IS CURRENTLY IN WIDE SPREAD USE ON NAVAL VESSELSAS AN EFFECTIVE AND NON-TOXIC ACTIVE AGENT IN FIRE SUPPRESSION SYSTEMS. UNFORTUNATELY, FUTURE MANUFACTURE AND USE OF CF3BR MAY BE SEVERELY RESTRICTED DUE TO ITS ROLE AS A POTENT AGENT IN STRATOSPHERIC OZONE DEPLETION CHEMISTRY. ALTERNATIVE FIRE SUPPRESSION CHEMICALS NEED TOBE IDENTIFIED AND ASSESSED TO REPLACE HALON 1301 IN NAVAL S ...

"Agiltron proposes a revolutionary approach to Mid-IR imager intrinsically having advantages in sensitivity, energy efficiency, reliability, and cost as compared with the competitive approaches. The innovation is based on pixel-level integration ofmicro-machined PbSe-Au interferometer that directly converts IR image into visible image providing unprecedented opportunity to produce affordable Mid-I ...

"This program addresses the development of a solid-state optical switching technology. Current optical switches do not simultaneously meet the requirements of high speed, low loss, high extinction ratio, low power consumption, high damage threshold, andhigh reliability. Sub-microsecond and multiple-port optical switches of low loss and low cost are long sought after performance attributes. This ...

"The traditional way of steering light is using turnable mirrors, prisms or other optical components by mechanical actuators. These are usually large, heavy and consume relatively high powers. Moreover, the rate/speed at which light can be modulated is slowcompared with today's demand on switching speeds and modulation frequencies. There is considerable value of adding non-mechanical steering of l ...

"Shipboard intelligence centers deployed in littoral regions arethe "front line" for naval intelligence gathering. Onboardcryptanalysts need to monitor multiple information sources fortrends and deviations from expected norms, detect and properlyinterpret the unusual, and generate Indications and Warning(I&W). Anticipated reductions in shipboard manning and increasesin the quantity of available ...

"Maritime Intelligence, Surveillance, and Reconnaissance (ISR) has been proven critical to national defense. Currently, E-2C, S-3B, P-3C and EP-3 aircraft are used to support the Navy's ISR primary missions. Desires to utilize UAVs have significantlyenabled platform advances, but still demand the development of small low cost, lower power ISR payloads.ALPHATECH and NAVSYS propose to integrate ALP ...

"Alphatech proposes a novel technique for Diagnostics, Prognostics, and Health Management (PHM) of interconnected mechanical subsystems, using physics-based models and multi-hypothesis technologies. In collaboration with Rolls-Royce, our effort is focusedtowards PHM development for the highly interconnected F35B LiftFan, to which our models and techniques will be applied. The goal of systems-lev ...

"In shallow water environments or using broadband processing, sonar signals can exhibit highly non-Gaussian noise statistics due to the discrete nature of the background returns from different clutter elements in different range/bearing resolution cells.Optimal likelihood detectors rely crucially on accurate noise statistics estimation, and poor fits to an assumed Gaussian PDF can lead to increase ...
