Atmospheric and Environmental Research, Inc. proposes to develop a prototype threat-reduction system for the dispersion of a weapons-of-mass destruction warhead in the upper atmosphere. Our system will extend current DTRA atmospheric transport and dispersion capabilities into the 20-120 km altitude region. This will be accomplished using a combination of a zonally-averaged transport model of the s ...

Physical Sciences Inc (PSI) proposes to enhance the performance of deep earth penetrators using fluid additives (gas, liquid) to mitigate the deleterious effects of interactions with natural and manmade heterogeneous target materials. In order to minimize these shear effects from the heterogeneous target impacts, we propose to envelope the projectile with innovative surface layers that create eit ...

The complexity of Atmospheric Transport and Dispersion (ATD) modeling requires physically consistent weather data evolving in both space and time. Spatially and/or temporally averaged data found in climatological products is not suitable for ATD modeling. The proposed solution for providing “typical day” meteorological data couples innovative search techniques applied to long-range historical ...

An optical sensor capable of producing 3-dimensional time resolved density maps characteristic of shock wavefronts at Mhz sampling rates is proposed. Each map is obtained from simultaneous measurements obtained with a novel refractometer capable of measuring integrated density fluctuations in air to better than 1 part in 3500 per centimeter path length at 1Mhz with good signal to noise (S/N=10). ...

Until now gamma radiation detection has required large single crystals of sensitive materials that are difficult to produce consistently on an industrial scale. In collaboration with a research group at the University of Texas at Arlington, Agiltron proposes to develop a new class of nanocomposite scintillator materials. The radiation detection characteristics of the synthetic nanoparticles in the ...

The atmospheric transport and dispersion (ATD) model requirements for describing the environmental conditions that are most likely to occur on any given day, called the "typical day", are very unique. The model requirements are unique because the typical day requirements for ATD must be both typical in representing the most likely occurring condition of each variable and be mass-balanced across t ...

SIMOX (Separation by IMplanted Oxygen) technology achieves total dielelectric isolation of active device regions from the substrate and reduces the collection path for ionized charges via the built-in buried oxide which restricts charge movement. Advances in SIMOX technology include radiation hardened memories and gate arrays for space applications, ULSI DRAMS for low voltage operation, thin film ...

Various procedures have been proposed for evaluation/mitigation of the potential for progressive collapse in the design and/or retrofit process. These range from passive procedures that evaluate the redundancy of structures to limit failure through redistribution of gravitation loads after key elements such as columns have been removed to complete nonlinear finite element analyses of buildings sub ...

OBJECTIVE: To provide innovative technologies and system components which increase the lifetime and utility of various systems within DTRA"s Tag, Track, and Locate (TTL) portfolio to combat weapons of mass destruction (WMD). The specific innovations sought under this topic are improved technologies that advance the state of the art for energy scavenging or capture from the ambient environment an ...

The proposed muti-mode imaging system will allow a combination of X-ray Backscatter imaging (proven successful in finding IEDs in AS&E's Z Backscatter Van) and other sensor modalities, such as vapor/trace detection and video, to be mounted on a robotic platform(the iRobot R-Gator) such that the system can be quickly moved into location to examine a potential threat, including WMD dispersal devices ...
