The Defense Threat Reduction Agency has expressed the need for waterborne transport and dispersion capability to compliment its existing models for Chemical, Biological, Radiological and Nuclear (CBRN) releases. DTRA's current capability is limited to the atmospheric transport of CBRN agents using the HPAC system. The objective of this proposed Phase I study is to couple Applied Science Associat ...

This project is the development of a single crystal underwater acoustic modem transducer for Unmanned Underwater Vehicles (UUV) which is compact in size, operates at low to moderately low center frequencies, in a broad band frequency range to accommodate state-of-the-art binary, FSK and spread spectrum signaling schemes that promote covertness. The device exploits the high coupling coefficient an ...

A yb laser at 976 nm is a three level system. By placing Sm in the core (to reduce stimulated emission above 1,000 nm) and Yb in a surrounding ring, a more efficient laser at 976 nm can be obtained. This will be Q-switched to serve as the first stage of a pulse source in a MOPA configuration. The second stage will be a HOM fiber designed to amplify the pulses from the first stage. With a HOM fiber ...

DBV Technology, LLC proposes to develop an acoustic instrumentation system for the Test & Evaluation of Trident D-5 munitions to support the geo-location of near simultaneous impacts on the sea surface of up to 500 projectiles within a 500 meter radius area to an accuracy less than 1 meter CEP referenced to WGS-84. The proposed system will leverage over ten years of DBV Technology experience in ba ...

Underwater acoustic modeling plays an essential role in the design, development, test, and operation of sonar systems. Active acoustic clutter can increase the sonar false alert rate or equivalently decrease the probability of detection/classification, and is a key issue in the development and utility of active sonar systems. The ability to predict reverberation and clutter is inseparably tied to ...

The ultimate objective of this SBIR project is the development of a software-based tool that provides environmental planners, synthetic trainers, and scientific researchers with access to scientific data on marine species. Ready access to pertinent information about a marine species, such as distribution, density, and behavior, is vital for making informed science-based decisions concerning the ma ...

The goal of this Phase I SBIR proposal is to design and build energy harvesting wireless sensing systems suitable for use aboard Navy Helicopters. The program will begin with a survey of typical vibration data obtained during flight testing; these data will then be used to optimize our existing vibration energy harvesting wireless sensors (VEWS) for use on Navy helicopters. These software progra ...

A major barrier to the widespread adoption of wireless sensors for structural health monitoring is the requirement to power the network of wireless nodes. Batteries have a limited lifespan, adding significant size, weight, and costs to the wireless sensor network,and may represent a long term environmental problem. Battery maintenance can be eliminated by harvesting energy from the environment. Fo ...

Structural monitoring of Navy aircraft is of critical importance as the fleet ages. One critical area includes the control surfaces, which are subject to intense, dynamic buffet loading which can lead to structural cracking. The highly transient nature of buffet loading makes it difficult to measure using conventional sensors. We propose to solve this problem by combining a network of time-synchro ...

SubChem Systems Inc. has been involved in the further development, deployment and commercialization of autonomous in-situ chemical analyzers and custom engineered payloads since 1996. SubChem Analyzers have been deployed on commercial AUVs, coastal gliders, autonomous moored vertical profilers, fixed moored structures and other ocean observation platforms. The overall objective of this funding wil ...
