Terrorists can employ small water craft, boats, submersibles and swimmers to detonate explosives along side ships, or attach devices to the hull above or below the waterline. Ship defense against “asymmetrical threat” targets such as multiple small boats in the complex littoral environment are made difficult by the limited capability of shipboard sensors to detect these targets among waves, a ...

Protection of ground troops and physical assets against hostile attacks on the battlefield is a crucial capability that must be provided by a combination of sensors and automated signal processing software that can function at all times, including in low-light/no-light and non-line-of-sight conditions. Existing surveillance sensor systems lack the automated ability to detect and classify threats. ...

High-frequency acoustic modems are required to provide undersea communication networks to support covert surveillance operations. These modems can also be used as platforms for compact, low power surveillance sensors and processing. A natural first step would be to integrate a capability for passive acoustic detection of ships and submarines. A multi-phase effort is proposed for integrating passiv ...

Nanofiber nonwoven spunbonded materials technology is adapted for use in a personnel lowering device. The resulting device will be simple, easy to use, and relatively low cost.

ADC is presenting a new method of nondestructive evaluation/inspection technology that enable the capability to detect improvised explosive devices (IEDs) carried or hidden within motor ve-hicles.

A definitive experimental study of photoemissive materials and cathode design and fabrication for RF electron injectors is proposed that will result in a recommended cathode approach for next step Navy FEL devices at the end of the program. The University of Maryland (UMD) and Brookhaven National Laboratory (BNL) are collaborating with Advanced Energy Systems (AES) on this project. As an FFRDC, ...

THz electromagnetic radiation in the frequency range from around 0.3 to 10 THz is an unexplored frontier in imaging science and technology whose application holds great promise for defense, medical imaging, drug discovery and homeland security. Present applications are limited by the availability of powerful sources and sensitive detectors. In Phase I of this program we propose to develop the de ...

This proposal presents a Phase I SBIR project to develop a high precision, low disperse rate powder disseminator for the US Army. In the development of the sensitive detecting agent, we need to release a precise amount of C&B agents in the controlled detection experiments. However, such a technology does not exist at the present time. After examining existing technologies, we believe that the r ...

In composites, not only can properties vary with load direction, fiber based composites also offer the unique ability to tailor material properties locally. Localized matrix or fiber architecture changes can meet local mechanical, electrical, or thermal loads within a component or vehicle, without weight penalty or resort to additional external structures. In Phase I, the team used 3TEX 3-D wea ...

During Phase I, 3TEX designed universal, one-piece, 3D woven fiber preforms which can be used as either a “Butt” (H) joint or as a “P” joint as needed. Composite joints were fabricated and tested, demonstrating the benefit of the integral nature of the 3D preforms. 3D stress/strain and crack propagation analysis of composite Π-joint was performed using 3D MOSAIC code. 3D displacement, st ...
