Recent efforts in the target vulnerability community (fixed ground targets, mobile ground targets, and aircraft) have focused on enhancing the blast and fragmentation modeling from weapon detonations. This includes modeling propagation of the detonation effects from the weapon through their interaction with the target geometry, to the development of loads on and response of the target structure. ...

Warhead design calculations and weapons effectiveness estimates require a methodology to predict structural response and the associated damage to air targets from reactive munitions. The objectives for the proposed Phase I study effort are to develop candidate launch conditioning, reaction initiation and reaction rate methodology, to incorporate existing ballistic, blast and quasi-static pres ...

Turbulence of gas flows by its very nature is one of the most difficult things to model and measure. We propose to develop a new way of measuring the turbulence and to compare these measurements to predictions using the k-epsilon model. Typical measurements, in the past, use smoke, Schlierin or shadow graph techniques to visually infer turbulence characteristics. These features are either motio ...

The objective of this work is to develop analytical techniques to characterize wear and gouging phenomena of slippers at speeds up to hypersonic and demonstrate means to evaluate or reduce slipper wear/gouging. Specifically, we will develop analytical techniques that can be used to predict slipper wear patterns and gouging phenomena throughout the sled velocity regime to Mach 10. This will inclu ...

Arca Systems proposes to initiate the design and development of an intrusion detection system for the GCCS LES (and similar environments). Many current intrusion detection tools are Unix-based, focused on a single host or on a generally homogeneous distributed environment. The notional GCCS LES environment makes extensive use of distributed architecture, using support from the COTS technologies ...

The goal of this SBIR proposal is to evaluate the suitability of the WESCAM Model 14 EO sensor, currently deployed in the Predator, for oceanographic research use in the Naval Postgraduate School's "Pelican" optionally piloted aircraft. Sensor specifications will be based on Arete's extensive experience in remote sensing of the ocean, and engineering specifications developed with the Naval P ...

The intent of this program is to develop workable concepts that will result in commercial and military high performance, covert, low cost, adaptable antennas in gain, coverage, and a variety of equipment applicability for hand held use. Ideally, the program will result in a technology capable of significantly foreshortening antennas (4:1) while maintaining low losses, hemispheric coverage, novel ...

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 ...

Controlling millimeter radio frequency waves with optical signals is a requirement for military communications and radar systems. The advances in the past decade have led to photonic sensors and switches that utilize light beams interacting with RF devices. New capabilities extending to higher frequencies and working over multiple frequency bands are possible using a combination of nonlinear op ...
