Office of Naval Research Summer Faculty Research & Sabbatical Leave Program
Naval Undersea Warfare Center - Newport Division

Only U.S. citizens will be considered for positions at this lab.

Dual citizens are NOT eligible.

The Naval Undersea Warfare Center Division, Newport (NUWCDIVNPT) is the Navy's full-spectrum research, development, test and evaluation, engineering and fleet support center for submarine warfare systems and many other systems associated with the undersea battlespace. NUWC Division Newport is responsible, cradle to grave, for all aspects of systems under its charter, and is engaged in efforts ranging from participation in fundamental research to the support of evolving operational capabilities in the U.S. Navy fleet.

With nearly 3,000 scientists and engineers, NUWCDIVNPT provides the technical foundation that enables the conceptualization, research, development, fielding, modernization, and maintenance of systems that ensure our Navy's undersea superiority. NUWCDIVNPT is on the forefront of developing and maintaining the best scientific and technical facilities for underwater research, supporting many important Navy programs and helping to minimize risk and cost of operations. Working closely with the Fleet, our scientists and engineers meet current and future operational requirements and solve technical problems.

NUWCDIVNPT specific research and technology areas include:

  • Structural Mechanics
  • Structural Acoustics
  • Fiber Optic Sensors and Arrays
  • Chemistry and Materials
  • Signal and Information Processing including Tracking, Classification, and Image Processing
  • Machine Learning

Below are two specific examples of research visiting summer faculty performed this past summer at NUWCDIVNPT:

Optimal and Suboptimal Subspace Estimation for 1D and 2D Uniform Sensor Arrays

Subspace estimation is an implicit or explicit part of signal processing tasks such as adaptive beamforming or direction-of-arrival estimation. A theoretical bound on the best achievable accuracy for subspace estimation and a new, closed-form, optimal subspace estimation (OSE) algorithm that achieves the bound has been derived. Signal processing tasks that use the OSE subspace inherit the benefits of its best achievable accuracy. However, the OSE calculations are prohibitive for arrays with a large number of sensors and the OSE subspace estimate is sensitive to perturbations such as array calibration errors. A newly proposed estimation method based on subspace averaging (SSA), while suboptimal with respect to accuracy, can approach that of OSE with less computation.

Neuromorphic Computing

Neuroscience techniques and the understanding of the brain’s circuits are advancing rapidly, but a large gap exists in transitioning this knowledge to computing hardware suitable for advanced neural information processing problems. In collaboration with several universities, basic research at NUWCDIVNPT is bridging the gap between computational neuroscience and reconfigurable computing by studying the dynamical equations that govern neural networks in order to develop reconfigurable neuromorphic devices capable of solving highly complex mathematical equations in real-time or faster-than-real-time scales.
