To support Navy Live, Virtual, and Constructive (LVC) training for surface fleets during periods of long transit, the Navy would like to implement an alternative communication path that can link shore-based trainers and simulation capabilities with trainers and training systems afloat. To support full spectrum training during the training events, there is a desire to selectively turn off communica ...

The goal of this effort is to develop the Arctic Power Station (APS), a rugged and clean energy source that will fundamentally alter the logistics and economics of Arctic observing system operations.  Engineers and scientists from Seatrec and the Woods Hole Oceanographic Institution (WHOI) will collaborate on a novel air-sea thermal energy harvesting system optimized to exploit the wintertime a ...

In Phase II, the machine learning (ML) model update strategies that were developed as part of Phase I efforts will be refined for different use-case scenarios. This includes developing and validating mathematical models on both the standard image/video datasets and the provided representative periscope imagery data. A system prototype will then be developed to enable timely vessel detection, ident ...

In the past few years, we have experimentally demonstrated that modulated radiation pressure (MRP) can be used to extract classification clues such as resonant frequencies, mode shapes and sizes for targets of interest.  These experiments were carried out at Washington State University (WSU) between (2015-2020) in water tanks involving scaled targets.  Using a 15-cm acoustic lens, MRP was appl ...

Improving the effectiveness of counter-WMD operations requires improved understanding of weapon-target interaction. Specifically, time-resolved measurements of temperature and composition are required to allow temporal evolution of a detonation fireball. To address this need, SA Photonics will develop MONITOR, a laser-based temperature diagnostic which will enable wide dynamic range temperature me ...

For effective protection against radiated threats, produced by high altitude electromagnetic pulse (HEMP) caused by nuclear detonations and high-power microwave (HPM) Directed Energy (DE) weapons it is important to understand not only the physics of the threats, but also to quantify the effects on mission-critical electrical systems. EMP/HMP simulators enable threat level testing of MCS and provid ...

Areté and the Machine Learning for Artificial Intelligence (MLAI) Lab at the University of Arizona (UA) will complete the development of an interactive scenario building tool to generate realistic simulation content in real-time for use in training simulators for periscope operators.  Areté calls this tool RealSim.  The novel capability is created by combining the latest advances in generative ...

High power generation at millimeter wave (mm-wave) frequencies is expensive and the concurrent need for wide bandwidths at these frequencies creates an extremely challenging problem. Currently the most stringent requirements for mm-wave power and bandwidth can only be practically met by vacuum electronics (VE) technology. At present, vacuum amplifiers with the required performance are prohibitivel ...

In the proposed STTR study, Catto Propellers, Inc. (Catto) and the University of North Dakota (UND) will create an efficient new propeller design utilizing advanced composite materials for use on small unmanned x systems. During Phase I, a comprehensive study will be conducted to develop a new propeller design in order to increase propeller efficiency, reduce aerodynamic noise and utilize innovati ...

The capability to model large-scale problems in electromagnetics (problem sizes extending to thousands of wavelengths) using physics-based full wave solvers that employ high-fidelity geometric models and high- order accurate numerical algorithms is a critical technology for several aspects of the DoD warfighter mission.  In particular, a robust and computationally efficient computational electrom ...
