MAI has been awarded a six-month Phase I SBIR for $140,000 to develop a feasibility study for an Intelligent Assistant for Anti-Submarine Warfare. Along with our new partners at Clarifai, we will be creating the SONAR Engagement Naval Systems Enhancing Intelligence (SENSEI) utilizing AI to bring together environmental information from the on-board tactical decision aid (TDA), in-situ, real-time assessment of the environment, and machine-learning algorithms to provide operators situational awareness regarding key parameters such as primary propagation path(s), bearing-dependent complications (such as sea mounts that might obscure threats), significant topology features into which a threat might retreat to minimize detection, best tactical waveforms, and situational best practices to enable operators to maximize the potential of the tactical sonar suite for the specific conditions present at that time and location.

MAI, in coordination with partners L3Harris, are pleased to announce the award of a Phase II Small Business Innovative Research (SBIR) grant for a Theater Anti-Submarine Warfare (TASW) Risk Analysis Tactical Decision Aid (TDA).

Theater Anti-Submarine Warfare (TASW) Planners may be overwhelmed by decisions regarding risk to future plans, according to current asset allocation (mitigation) against potential threats. At the Commander, Task Force (CTF) Watchfloor, the TASW planners have a series of resources to analyze risk vs mitigations to current TASW operations, to include a Common Operating Picture (COP), METOC and Intel Support. The Undersea Warfare Decision Support System (USW-DSS), a Command and Control (C2) system, was designed to help fuse this data into an ASW tactical picture, however, current USW-DSS functionality lacks risk analysis mission planning capability that captures the full needs of the disparate users in both understanding and assessing risk (relative to existing mitigation measures) to future plans.

MAI, in coordination with partners In-Depth Engineering Corp (IEC) and L3Harris, is pleased to announce the award of a Department of Defense Rapid Innovation Fund (RIF) for the development of a Cooperative Sonar Engagement capability for Theater ASW (C-SET).  C-SET delivers networked mission planning and communication capability to optimize cooperative use of Anti-Submarine Warfare (ASW) assets, optimizing placement of receive sensors and platforms capable of active emissions for bistatic active sonar. This capability leverages both existing Advanced Processing and Capability (AxB) sonar builds and Undersea Warfare Decision Support System (USW-DSS) architecture, and an at-sea demo utilizing Program Executive Office Integrated Warfare Systems (PEO-IWS) 5A sponsor resources is anticipated within the 2-year RIF period.

Jennifer Amaral published an article on the “Characterization of impact pile driving signals during installation of offshore wind turbine foundations” in the Journal of the Acoustical Society of America.  The article analyzes acoustic measurements collected with funding from the Bureau of Ocean Energy Management and in conjunction with the University of Rhode Island and Woods Hole Oceanographic Institution during pile driving for the foundations at the first offshore wind farm in U.S. waters. Metrics of rise and decay time, pulse duration, kurtosis, and sound pressure levels were characterized to investigate the impulsiveness of the pile driving signal over range. Variations in the radiated sound field were observed along different azimuths and were further investigated through finite element modeling.
