Modeling and simulation (M&S) provides the potential of serving as a cost-effective expedient for developing, acquiring, testing, and fielding new technologies for the future battlefield-provided the limitations of existing tools and techniques can be overcome. As the Army focal point for communications M&S, the U.S. Army Communications-Electronic Command (CECOM) has the lead for performing M&S t ...

A purely signal processing approach is proposed for generating high resolution synthetic aperture images from the millimeter wave tank-mounted MTi radar being developed by the Army. Such images provide an all-weather, day/night target classification and fire control capability to the tank commander. The greatly enhanced functionality of the system is obtained throught the addition of a low-cost, ...

Federal facilities contaminated with low level radioactive materials such as uranium in soil are currently remediated by stabilizing or disposing of the contaminated soil. Conventional approaches to this problem are expensive. A new environmental technology which uses specially selected metal-accumulating plants to clean up soil contaminated with heavy metals may be applicable to the treatment o ...

PSI's CAD approach to discrete event modeling and simulatin has cut large scale simulation life cycle by as much as an order of magnitude. This approach, based upon significant departures in technical concept and approach, prvides ease of control and reuse of complex models. It has broken the barriers to modeling complex systems, yeilding the very high resolution models required to insure validi ...

PSI's CAD approach to simulation/software development has cut large scale life cycle costs by an order of magnitude. This approach, based upon significant departures in technical concepts, provides ease of control and reuse of complex software modules. It has broken barriers to building complex systems, making significant upgrades easy to evolve, and cutting support costs dramatically. This is ...

Image intensifiers based on Negative Electron Affinity (NEA) photocathodes and microchannel plates which are called Generation III image intensifiers suffer from a major limitation of having the long wavelength cutoff only to about 950nm. For that reason, it has poor modulation transfer function and correspondingly lower performance in starlight and in the overcast starlight light levels. To dev ...

We propose to develop and deliver a high-performance 1280x960 element camera for low-light imaging of 1-2 ¿m light. The night sky provides illumination from moonlight, starlight, and "night glow". In the absence of moon and starlight, the primary radiance is from night glow in the 1-2 ¿m band peaking at 1.6 ¿m. During this program, we will develop and deliver an InxGa1-xAs-based low-l ...

This proposal address the inefficiences inherent in transmitttng tactical voice over ATM networks using Constant Bit Rate (CBR) methods. It proposes to perform the research and development necessary to design a Variable Bit Rate (VBR) interface that will tailor the bandwidth used by tactical voice traffic to the actual syllabic speech activity on the individual channels. This interface will allo ...
