The Phase I technical objective is to design a small "virtual" receiving antenna which will operate in the HF, VHF, and UHF frequency ranges (approximately 1 MHz to 1500 MHz) and then to build and test a laboratory prototype. The virtual antenna will be capable of duplicating electrically, but not physically, the wide variety of antennas necessary to receive HF, VHF, and UHF signals. The virtual a ...

The contractor has patented technology for a unique process that directly converts a two-dimensional acoustic disturbance, such as a wave front, into an intensity-mapped visible image in real-time without electronic circuitry; that is, it is a direct pressure gradient imager. The imager relies on the piezo-dichroic properties of a continuous layer of a dichroic material thin film that serves as bo ...

The objective of this study is to design an advanced inflatable boat that will meet the special needs of U.S. Navy SEALs and be deployable from a submerged submarine in hostile waters. For "Stealth", radar, sonar, infra-red and audio signatures will be suppressed by incorporating features such as hydrodynamic shaping to minimize wake and spray generation and by selecting materials and structures h ...

This proposal develops design details and materials concepts for a Collapsible Rigid Inflatable Boat (C-RIB). The proposal seeks to develop a seaworthy prototype within Phase I budgets and time- frames. A multi-disciplined team approach will develop a lightweight, armored, low observable craft launchable from submarines, aircraft, and surface vessels. Commercial versions are contemplated in collap ...

One mission of the Naval Special Warfare forces is both location and neutralization of very shallow water anit-invasion mines. This proposal addresses the mine neutralization aspect of the problem. PDA has been developing high speed underwater rockets and projectiles for the past six years for the Navy, primarily under the sponsorship of the Naval Undersea Warfare Center (NUWC). The performance of ...

Naval Special Warfare is developing and testing equipment and tactics for neutralization of anti-invasion mines in the very shallow water maritime environment. The device proposed herein, an electromagnetic pulse mine countermeasure device, will enhance the capability of Naval Special Warfare to neutralize mines. The proposed device is expected to be effective against most, if not all, mine types, ...

Accuwave Corporation will study the feasibility of a volume holographic, phase-encoded optical image correlator for credit card and document validation and security application. Fourier transform holograms of a phase-encoded input image are stored using wavelength multiplexed holographic gratings in a photorefractive crystal. High spatial resolution images can be sotred with low crosstalk using ...
