Atlantic Aerospace proposes to develop an Active Sonar Display Processor (ASDP) to distinguish between submarine and non-submarine contacts in airborne active sonar systems. Accurate active classification of anti-submarine warfare (ASW) sonar echoes is a long standing need for the Navy. Current system performance is based upon an operator viewing the sonar screen and making classifications based ...

The objective of this proposal is to formulate an innovative modeling approach for a reactive fragment impact with a target, based on first-order, simplified engineering analysis of key physical and chemical processes. These processes include fragment break-up, energy release rates, energy deposition rates into the target and target failure. The model will relate these processes to practical des ...

Evolving military applications require higher computing performance which is Nrealized by increasing the number of processors or the processor clock speed. F Trends toward sharing resources in multi-processor systems and using Mdistributed processing systems for reliability and speed place more emphasis @on availability of a wide bandwidth network to interconnect the Nmicroprocessors. The add ...

We have developed a unique tool based on Nuclear Magnetic Resonance (NMR) Imaging methods, for the study of the microscopic structure of polymer matrices. We believe that these methods are uniquely suited to the study of cure shrinkage and aging in rocket motor propellants, and we propose to work with DOD collaborators to demonstrate this capability and to employ our imaging methods in laborat ...

Statistical Energy Analysis (SEA)is currently used to predict high-frequency airborne and structureborne noise and vibration for ships, aircraft, aerospace systems, and automobiles, while finite element analysis (FEA) is used for low-frequencies. A mid-frequency region exists where neither technique gives accurate predictions. The study being proposed will develop modeling procedures that a ...

A new family of surface-active organic compounds is proposed for formulating multi-purpose vapor phase corrosion inhibitors (VCI's). The proposed research explores the feasibility of applying state-of-the-art surface science with the concepts of molecular simulation and molecular self assembly to produce a new class of corrosion inhibitors. The ultimate objective is to develop a family of VCI's ...

The digitization of the tactical military environment with its concomitant increase in accessible information provides an opportunity to enhance decision-aiding capabilities of advanced Navy targeting systems. An approach employing intelligent software agents can facilitate enhanced decision-aiding by automating: the management and dissemination of relevant targeting information and intelligence ...

The objective of this project is to develop adaptive channel characterization algorithms for very low frequency (VLF) covert acoustic communications between submarines and other platforms. Technical issues that are addressed are channel propagation conditions in the VLF band and channel characterization; the impact of submarine motion on the signals transmitted in this band; and determination of o ...

In the proposed Phase I program, DeMaria ElectroOptics Systems, Inc (DEOS) will explore innovative non-linear techniques based on frequency conversion of long wavelength pump lasers using AgGaSe2 crystals and other potential non-linear crystals that if successful will enable the construction of a high repetition rate, 5 -10 watt, 7.5 micron - 9 micron laser system in Phase II that meets bot ...

The polymer film located between the fingers of a metal grid is a critical element in developing an operational electrochromic switch on a poly(tetrafluoroethylene) substrate. The polymer must be thin and highly conductive in one state to give the switch both a rapid response and a high contrast ratio. In addition, overlap of the polymer onto the top of the grids increases the charge require ...
