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 ...

1Innovative techniques for radar high angle resolution are proposed for investigation in a Phase I effort to enable the resolution of the direction of arrival (DOA) of returns from multiple targets that fall within one beamwidth and within the same range and Doppler Cells. The techniques proposed emphasize the pursuit for optimal utilization of available aperture space, by a combination of arrange ...

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 ...

change induced in the wavelength of ruby R-line fluorescence. Timehe resolution will be 0.1 microsecond. Axi innovative detector of this wavelength shift avoids the need for a dispersive optical system and streak camera, as previously used. The fluorescence will be excited by an argon ion laser. materials having less temperature sensitivity than ruby, and the use of non-laser excitation sources.

esign of the IR/RF payloads.

This exploratory development proposal addresses a class of novel algorithms specifically designed for tracking and engaging maneuvering air, naval or ground targets. The key technical innovation is the development of linear and nonlinear target tracking algorithms using the recent results in H(Infinity) estimation methodology to modify the classical Kalman filter and extended Kalman filter algorit ...

1An UWB data link is proposed to be added to an existing ANRO impulse radar sensor by creating a block orthogonal transmission scheme (e.g., pulse position modulation) where one of M equal-energy orthogonal signals is transmitted each pulse repetition period together with the radar main bang. Synchronization of the down-link data channel is accomplished by radiating a separate orthogonally polariz ...
