The development of a generalized moving body capability for Computational Fluid Dynamics (CFD) flow simulations of highly transient flowfields is critical to system analyses of Divert and Attitude Control Systems (DACS) for Kinetic Warheads (KWs). Testing capabilities are limited in the DACS operating regime; therefore, computational tools are essential for such analyses. The flow in the DACS its ...

The pressing need exists within industry to accurately measure high aspect ratio microscale structures. For example, diesel injector nozzles are manufactured with microscale holes ranging from 50-200 micrometers in diameter and 3-5 mm depths. One fundamental challenge is to nondestrucvely measure these features in order to validate models, enhance manufacturing processes, and reduce fuel emissions ...

Integrated Sensors, Incorporated proposes to develop and demonstrate techniques that effect practical, operationally meaningful, simultaneous mainlobe/sidelobe jamming cancellation in solid state, active array radars while preserving target angular accuracies and permit operation in clutter and jamming environments. Two innovative and promising architectures will be examined: (a) an Adaptive Maxi ...

Integrated Sensors, Incorporated (ISI) proposes to develop a frequency-domain closely spaced object (CSO) condition detection algorithm and evaluate a variety of deconvolution approaches. We propose a combined CSO / deconvolution process where information extracted from the CSO detection process will drive the design of the deconvolution filters. We will also use the CSO information to characteriz ...

Manning Applied Technology proposes to develop a handheld infrared spectrometer, ideally suited to detection of airborne chemical agents at and below permissible exposure limits. This approach offers unmatched sensitivity and specificity for detection of all types of chemical vapors. The instrument is modular, rugged, compact and highly sensitive. Volume pricing will be less than $1000 each. ...

Optical systems are continually being designed to meet more difficult and challenging performance specifications and applications. Specifically, airborne and space optics are employing larger diameter surfaces with more stringent figure requirements. In order to meet these demands, individual optical surfaces are being given increasingly strict tolerances. The traditional peak-to-valley (PV) and ...

High precision, lightweight optics are required for numerous seekers, aircraft, and satellites programs. Current system demands require that the optics operate in a variety of conditions and in wavelengths from the visible to very long wave IR. This translates into a need for large (up to 30 cm) mirrors in difficult to manufacture materials, e.g., SiC, with surface requirements that meet or exceed ...

Buffer overflow attack is the main attack method that most if not all existing malicious worms use to propagate themselves from machine to machine. Despite the fact that buffer overflow bug is a well known programming problem, existing and new network applications continue to exhibit this type of vulnerability, thus exposing themselves to remote exploits. Although a great deal of research has been ...

Infrared surveillance and tracking systems use intensity/temporal properties of observed missile signatures to develop information that assists in the typing and/or characterization of the target, a task of primary importance to boost phase intercept and other defense systems and activities. An important characteristic feature, afterburning cessation (i.e., the very rapid drop in the observed sig ...

Real-time fusion of data collected from a variety of radars that acquire information from multiple perspectives and/or different frequencies, is being shown to provide a more accurate picture of the adversary threat cloud than any single radar or group of radars operating independently. This assumes that the proper constraints (decision algorithms) are applied to the midcourse ballistic vehicle t ...
