"Recent studies have shown that the performance of Space-Time Adaptive Processing (STAP) degrades when there are moving targets in the secondary training data. Although a variety of techniques have been proposed for controlling the effects of targets inthe secondary data (TSD), these techniques generally do not take advantage of external information. We are developing knowledge-based STAP (KBSTA ...

"We propose novel data-adaptive approaches for processing synthetic aperture radar (SAR) phase history data to automatically assess subtle damage inflicted by small sub-munitions on military ground vehicles. These techniques are designed for a battlefieldscenario in which the ground vehicle under attack is illuminated by a stand-off airborne SAR sensor before, during and after the weapon strike, ...

"The proposed research mimics the adhesive strategy of the tokay gecko to produce a novel, dry, self-cleaning dynamically modulated adhesive. A soft mat of artificial hairs allows the adhesive force of the sticky spatulae to be modulated. This facilitateseasy engagement and disengagement with the surface, as well as promoting self-cleaning."

"Novel fracture-initiated resin additives are proposed for fabricating polymer matrix composites with the ability to self-repair after sustaining structural damage. The Phase I objective was to develop an easily processed resin system with strong adhesionto reinforcing fibers, high thermal stability, robust reactivity over a wide temperature range, and the ability to recover mechanical properties ...

"Military command posts of the future are increasingly likely to be located in or near densely populated urban environments. Due to occluding building and trees, these environments make it impossible for a single sensor to monitor potentially threateningevents over an extended period of time. Therefore, the command post must deploy and efficiently monitor a large number of video cameras in order ...

"The objective of the proposed SBIR Phase II proposal is to provide a major advance in the development of polymer thin film ferroelectrics for microwave device applications. In the Phase I program, we have demonstrated a 50% change in the dielectricconstant at 1.0 V bias voltage applied, a significant improvement in device performance compared to competing barium strontium titanate based devices ...

"Mass Injection Pre-Compressor Cooling (MIPCC) is a promising technology which can permit convention jet engines, normally limited in speed and altitude, to propel aircraft to substantially higher altitudes and velocities. By injecting coolant ahead of thecompressor and using its heat of vaporization to cool inlet gasses, the engine can operate at substantially higher velocities without exceeding ...

"The requirement for an underwater sympathetic detonation detector arises from the need to provide a reliable trigger signal under all conditions. The object of the Phase 2 is to transition from the current laboratory proof-of-principle brassboard to asystem that can be integrated into the existing SYDET hardware and that has low power/energy requirements. The aim of the proposed program is to bui ...

"DARPA is undertaking a revolutionary increase in density of high performance embedded computing architectures in the Polymorphous Computing Architecture (PCA) program. If the revolutionary increase in computing capacity PCA architectures will offer can beefficiently and economically utilized, PCA technology can spur a revolution in new capabilities of systems utilizing embedded computing. Curre ...

"The potential use of biological and chemical warfare agents presents a threat to both military and civilian communities. The properties of biofilms can be exploited to improve the detection of these agents. Biofilms consist of microorganisms growing on asurface and enmeshed in a polymer matrix. Observation of biofilms in a variety of environments indicate they have a natural ability to capture a ...
