The program objective is to develop novel designs, techniques, and structures to synthesize apertures capable of efficient operation over broad frequency ranges and functions. Conventional apertures are narrowly focused, application specific, and basically single point design. To decrease the cost of antennas, a more universal building block design is required. It would provide a significantly ...

We propose a plan sentinel prototype consisting of three components. The first component is the development of a plan mining tool which identifies and computes false or missing assumptions and deviations to plans and time phased tasks. The second component, the annotated database, computes plans which the plan mining tool access and parses into a logical annotated rule set. Finally, MAVIS, a to ...

Improved magnetic and electromagnetic sensors covering a wide range of frequencies, 0 to 10kHz, and with extremely high sensitivity are proposed for broad area detection and characterization of underground targets. The sensors can be used for a variety of applications and for different e.m. sources. They can be configured as gradiometers, as vector or scaler sensors and can be used as internette ...

DECISION SCIENCE CONSORTIUM, INC. (DSC) PROPOSES TO ENGAGE IN AN INNOVATIVE RESEARCH PROGRAM TO DESIGN AND IMPLEMENT AN ADVERSARIAL PLANNING SYSTEM THAT IS ABLE TO REASON ABOUT THE PERSISTENCE OVER TIME OF AN ADVERSARY'S BELIEF AND INTENTIONS. SPECIFICALLY, THIS SYSTEM WILL UTILIZE EITHER A NONMONOLITHIC SITUATIONAL OR TEMPORAL LOGIC TO DETERMINE THE EXTENT TO WHICH AN ADVERSARY'S PRESENT BELIEFS ...

AN INNOVATIVE RF EM MODULATION RADAR SENSOR IS PROPOSED WHICH WILL PROVIDE A RICH, MULTI-SPECTRAL RESPONSE FROM RELOCATABLE STRATEGIC TARGETS. THIS NOVEL RF SYSTEM HAS THE FOLLOWING MAJOR ADVANTAGES OVER COMPETING RADAR SYSTEMS. A. IN ADDITION TO PROVIDIG THE CONVENTIONAL RADAR RETURN, A SECONDARY PHASE MODULATION IS INTRODUCED WHICH PROVIDES A UNIQUE RESPONSE CAPABLE OF FURTHER TARGET CHARACTERIZ ...

There is a need for simple, light-weight practical instrumentation for rapid characterization of chemical and biological analytes in the modern battlefield. Recently, a surface-sensitive diode laser (SSDL), having over 1% of the mode power in the region extending 40 nm from the laser surface has been designed and fabricated. The SSDL was capable of monitoring the deposition of absorptive films a ...

This DARPA SBIR Phase I project will demonstrate the feasibility of revolutionary ionic self-assembly methods of creating electric field-tunable thin-film electronic materials and devices. Exciting recent work at F&S and Virginia Tech has shown that the ionic nature of the self-assembly process inherently results in the spontaneous regular geometric ordering of noncentrosymmetric dipole molecules. ...

Events including the Oklahoma CIty bombing and the Sarin attack in the Tokyo subway have emphasized the vulnerability of personnel, both military and civilian, to unexpected attack with conventional explosives and chemical substances. To combat this threat requires portable, low cost sensor systems capable of detecting a variety of dangerous materials at extremely low concentrations. Such a tech ...

Many simulations environments, particularly those used for training purposes, employ simulated human behavior. To date, users frequently complain that such simulated behavior is not very intelligent and easy to "game" thus reducing the effectiveness of the training. We propose to improve intelligent agent technology through improved techniques for eliciting expert problem solving knowledge on wh ...
