The program objective is to demonstrate enhanced antenna element gain enhancement for small light weight synthesized virtual antennas. Astron/VPI have proposed a series of innovative helicalantennas to support the improved performance of a multi-element synthesized virtual antenna.

The Engineering of Complex Systems(ECS) is a technology development initiative being conducted by the Naval surface Warfare Center Dahlgren Division to formalize and standardize the process and tools associated with applying system engineering to computer intensive (complex) systems. The enabling capabilities required are heavily dependent on increasing levels of automation. The automated techniqu ...

Corrosion of aircraft poses many problems including safety risks, higher maintenance costs, and reduced, operational effectiveness. Detection of corrosion on aircraft is difficult because corrosion often occurs in hidden places, requiring extended maintenance periods for disassembly. A corrosion detection system is proposed utilizing self contained sensors affixed to the aircraft. Novel sensors ...

The objective of this project is to develop methodology and prototype algorithms for object-level change detection and change explanation using structural SAR image data. Structural SAR image is obtained by the filtration, detion and transformation of local pixel-level formations of strong and weak electromagnetic (EM) responses into higher-level geometric and morphological micro-elements. These ...

We propose to develop an Automated Resource Optimization (ARO) prototype for efficiently solving many resource allocation problems encountered in the design of large scale complex systems. Our proposed approach is based on a novel optimization framework, the Nested Partitions Method. The main goal of the proposed Phase I effort will be to demonstrate the feasibility of the ARO prototype. The Phase ...

Production Products will develop a lightweight, modular, easily deployable barrier system that will be based on out proven polyurethane composite technology that has demonstrated the ability to absorb very high levels of elongation and energy without failure. This material can be elongated 500% repeatedly and still returns to it's original shape. We will design a barrier system around this struc ...

Tension systems proposes to build lightweight, portable, blast-resistant barriers using tensigritic structures that consist of: an inner and outer fabric or film skin; discontinuous compressive members; connective tensile elements of Vectran cordage; proprietary mechanical connectors to attach the skins, compressive and tensile members; and an anchoring system. The size and shape of barrier proto ...

The Defense Modeling and Simulation Office (DMSO) has developed the High Level Architecture (HLA) as one of the principle components of a DoD-wide Common Technical Framework for modeling and simulation (M&S). Unlike previous distributed simulation technologies such as DIS and SIMNET, HLA provides federation developers, via the Object Model Template (OMT), the means to define the structure and for ...

The contractor proposes a new approach to underwater imaging that directly converts a two-dimmensional acoustic pressure wave into an electronic requirements fo convential piezo-element arrays. The imager relies on the piezo-birefringent properties of a nematic liquid crystal panel that serves as both sensor and display. The capability of nematic liquid crystals has been established and publishe ...
