The TSC team proposes to develop a new generalized Space-Time Adaptive Processing (Generalized STAP) algorithm that discriminates among classes of scatterers. The new generalized formalism is applied to the problem of 3D ISAR imaging of the reentry vehicle (RV) or another object in the ballistic missile threat complex that suppresses radar dipole clutter, using multiple ground-based radars operat ...

Techno-Sciences, Inc. (TSi) in collaboration with the Smart Structures Laboratory Laboratory at the University of Maryland, College Park (UMCP), proposes to develop an innovative energy harvesting device suitable for integration with electronics for data acquisition and wireless transmission used as a node. The energy harvester will be mounted to a substructure and use ambient vibrations for ener ...

The presence of residual explosive materials in areas previously used as ranges by the US military presents a significant safety and environmental health hazard. Current methods of detecting explosives in soils require extensive soil and/or water sampling and analysis using portable laboratories. These impose significant cost and time burdens during the site remediation process. In this Phase I ...

Triton Systems, Inc., with Prof Aleksandr Simonian of Auburn University proposes to develop an in-situ, on-site, near real time response detector of explosive particles in large areas of soil for the BRAC program. The explosive detector is designed to withstand the environmental factors such as pH, temperature, soil moisture, and salinity changes of soil. The device detects ultra-low concentration ...

The insider threat remains one of the most difficult to detect -- left alone to mitigate -- threats against information systems. The overall objective of the effort (Phase I and Phase II) is to produce and prototype a Distributed Insider Threat Detection System (DITDS) for distributed environments, capable of identifying and quantifying emerging insider threats against the network, allowing for t ...

Static organization charts and standard processes define roles, methods, and authority in useful ways for common missions. But these same, rigid structures force the organization to behave inefficiently, often ineffectively on problems in new domains, problems requiring new coordination methods and ad hoc teams. What is needed to facilitate rapid formation of effective human networks is a system ...

We propose to develop high-fidelity numerical simulation tools to be used in the analysis and assessment of bone conduction of sound in the human head and the desigh of noise protection devices. The proposed approach utilizes boundary and volumetric integral equation methods, and will constitute an extension of our currently developed approach from acoustics to coupled elasticity-theory and acou ...

Combustion instability in liquid rocket engines (LREs) has manifested in nearly all LRE development programs. While the driving mechanisms of combustion instability are vast and coupled, in all instances, the net result is significant cost and schedule over-runs. In today’s business environment, such over-runs are rarely tolerated and generally result in program cancellations. Development of hig ...

Ammonium perchlorate (AP) is the most commonly used oxidizing ingredient in solid propellant formulations. It carries a sufficient excess of oxygen to allow for the combustion of the required binder and added metal, such as aluminum. The major drawback of AP is its chlorine content which results in the formation of large amounts of HCl as a combustion product and causes severe environmental proble ...

Busek Co. Inc. and Stanford University propose to jointly develop and test a high power plasma propulsion concept called the Coaxial High EnerGy (CHENG) thruster. This high efficiency (> 85%) pulsed system will be capable of average thrust levels commensurate to chemical propulsion (10^4 N/m^2), but with an Isp comparable to electrostatic propulsion (4000-50,000 s). Both thrust and Isp will be va ...
