The Defense Modeling and Simulation Office (DMSO) has developed the High Level Architecture (HLA) as one of the principle components of a DoD-wide Common Technical Framework for modeling and simulation (M&S). Unlike previous distributed simulation technologies such as DIS and SIMNET, HLA provides federation developers, via the Object Model Template (OMT), the means to define the structure and for ...

New methods that will significantly improve the performance of focal plane array systems are proposed . In particular the problem of target track reacquisition ( lost due to cloud clutter effects) will be studied in detail . We propose to investigate the applications of (1) the method of "smart averaging " ( introduced and developed by Boeing) and extensions thereof (2) Probabilistic methods, to t ...

To be economically attractive, weight and performance for small earth-to-orbit launch systems and station keeping space vehicles must be improved at significantly lower costs, while maintaining required payloads. A major weight and cost factor in any of these devices is the tankage for propellants and pressurant gases. Innovative and proven manufacturing technologies such as electroforming have be ...

The fabrication of highly efficient Faraday-active optical waveguide structures is proposed. Faraday-active waveguides are presently of great interest as their development is the critical enabling technology associated with the demonstration of an all-fiber optical circulator. Such devices, which may be characterized as multiport nonreciprocal polarization rotators, provide a means by which the te ...

For over two decades, researchers have investigated a wide variety of technologies for use as a real-time infrared scene generator. The key element necessary to develop a practical and cost effective infrared scene projector for test and evaluation of infrared sensors and seekers is a real-time thermal infrared scene generation device. During the past several years, the most promising technology t ...

Cryogenic components are being proposed for a ground-transportable radar (GTR) systems. Incorporating low-loss components into power-electronic based systems is a concern from the standpoint of system stability due to the inherent low resistance of the cryogenic components which may tend to destabilize the system due to reduced damping. The purpose of the work proposed herein is first to investiga ...

PPT, in collaboration with the Jet Propulsion Laboratory, proposes to develop a manufacturable packaging technology for monolithic Wavelength Division Multiplexing (WDM) laser arrays for all-optical fiber communications. The packaging technology will include coupling from a monolithic laser array to individual fibers and a microwave feed for each of the individual elements, all in a hermetically s ...

This Phase I Small Business Innovation Research project aims to develop a novel and highly versatile family of NLO crystals that may overcome the limitations of conventional technology. These materials are multifunctional and exhibit a number of unique properties that include, high nonlinearities, high damage thresholds, wide transparency range, are non-hygroscopic, and melt congruently. The uni ...

In order for Knowledge-Based Systems to continue progressing into the mainstream of computing technology, they must become capable of addressing large and complex problems. Conventional systems are achieving this progress by moving to network infrastructure models, distributed systems, and finer granularity that is object-oriented. Analogous architectures are needed for Knowledge-Based Systems so ...

Recent laboratory demonstrations have shown that time-domain persistent spectral holeburning memory can achieve record areal densities and density-bandwidth products. The same work has shown that many kilobits of data can be spectrally multiplexed within single spatial storage locations. These factors, taken together, open the door to an entirely new class of optical data storage, i.e., read/write ...
