OBJECTIVE: Develop and
transition key building blocks of a Multi-Dimensional Ambient Noise Model.
DESCRIPTION: In light of an
increasingly competitive undersea operational arena, the Navy is in need of a
replacement for the current omni-directional ambient noise model. The
envisioned replacement will be a Multi-Dimensional Ambient Noise Model that in
full form predicts the vector and statistics of the temporally dependent
ambient noise field as a function of location, direction, and season over a
broad range of tactical frequencies (10s of Hz to 100s of kHz) and operational
environments. The fully formed model will include a comprehensive
understanding of sea surface, volume, and bottom noise generation, attenuation
and propagation to the underwater sound field (included but not limited to:
biologics, acoustic seafloor loss mechanisms, and scattering). Additionally,
the model and supporting database will be formed and informed via data assimilation
from multiple sources (included but not limited to: Automatic Identification
System (AIS) data, marine weather, dedicated passive listening systems, and
feeds from tactical Navy sensors).
PHASE I: Develop a framework
for a Multi-Dimensional Ambient Noise Model (MDANM). Analyze and specify the
sonar or other data requirements necessary to develop and support it. In
addition, provide details of the proposed techniques to be used to estimate one
or more of the key MDANM parameters to include strategies for how this data can
be obtained operationally. Identify architecture, protocols, and formats for
MDANM output to the next-generation Submarine Tactical Decision Aid (STDA).
Phase I should include plans for a prototype MDANM to be created in Phase II.
PHASE II: Using operational
sonar or other measurement data, refine the methodology and conduct
proof-of-concept demonstrations and tests to estimate one or more of the key
MDANM parameters and the impact of the increased granularity (in location down
to a 5-km scale and direction to 10 degrees) of the predicted noise field on
the design and operation of a candidate operational sonar system. Develop partnerships
with Program Executive Office Integrated Warfare Systems Undersea Systems (PEO
IWS-5) and other stakeholders in development of next-generation tactical
decision aid (Advanced Processer Build – 2021 - APB 21).
PHASE III DUAL USE
APPLICATIONS: The Phase III effort will require coordination with the Naval
Surface Warfare Center, Carderock Division to add the MDANM to the STDA for
submarines, and potentially to the Sonar Performance Predictions Functional
Segment (SPPFS-STDA) for surface ship configurations and the STDA for
Integrated Undersea Surveillance System (IUSS), or STDA-I, for surveillance
