Multi-Dimensional Ambient Noise Model (MDANM) -- 22-094

The proposed technical effort centers on the continued development of tools for forecasting ocean ambient noise.  A prototype version of the Multi-Dimensional Ambient Noise Model (MDANM) has been delivered to the Oceanographic and Atmospheric Master Library for technical review.  The next iteration of the software will be transitioned to a production language suitable to run on Navy tactical and combat system infrastructure. The final product will enhance and expand the Navy’s existing sensor performance modeling capabilities.  The specific target platforms are the Common Tactical Decision Aid (CTDA), AWESIM, and other oceanographic tactical decision aids maintained by NAVAIR and CNMOC.  A design methodology will be adopted to facilitate and simplify future integration into other TDA variants, such as SPPFS, STDA-I, USW-DSS, ASPECT, and others.   MDANM’s underlying capability to model directional and multi-element sensors creates countless transition opportunities inside and outside the government domain.  The subsequent phase II creates new opportunities to use rapid prototyping to demonstrate additional capabilities beyond the core feature set for the CTDA transition target.  Each prototype to be developed will be fully functional, and later iterations will expand the feature set.  This enables the Navy and other potential customers to evaluate the progress and provide the feedback necessary to guide the project to a final deliverable that maximizes utility and offers the added benefit of guiding and informing future investment in this area.
