OBJECTIVE: Develop a software
application that simulates the effects of wave clutter for the AEGIS Combat
System (ACS) to enhance its design and validation of sensor detection and
tracking in Anti-Surface Warfare (ASuW) and Anti-Air Warfare (AAW).
Due to ever-evolving threats across ASuW and AAW and the manner in which they
are being deployed, a software application is needed that can instantaneously
determine the clutter created by sea waves and its impact on detection and/or
tracking operations to improve the overall performance of ACS. This software application is necessary to assess and
identify improvements in the combat system design in order to mitigate the
effects of wave clutter and improve performance against existing and future
threats. ACS detection and tracking utilizes track quality to establish and maintain
data on valid contacts in order to optimally resource sensors. Environmental
effects such as waves can cause intermittent and unpredictable false tracks
that may affect track viability and management. Modeling wave characteristics
is challenging due to the complexity of characterizing waveforms and their
interaction with other objects. Experimental models do not accurately
characterize or predict wave phenomena. They require significant processing
time and hardware resources, and do not capture the fidelity required to
function in test or operational environments.
PHASE I: Develop a concept
for a software application that simulates the effects of wave clutter and
enhances design and validation of sensor detection and tracking in ASUW and AAW
within the ACS. The concept will support the test capabilities identified in
the description. Feasibility will be established by evaluation of the proposed
software application to incorporate physics-based mathematical models
representative of wave effects. The Phase I Option, if awarded, will include
the initial design specifications and capabilities description to build a
prototype in Phase II. Develop a Phase II plan.
PHASE II: Based on the
results of Phase I and the Phase II Statement of Work (SOW), design, develop,
and deliver a prototype wave clutter software application that demonstrates the
capability to model sea wave clutter in the CSTB, which represents the combat
system test environment. The sea wave clutter software application must be
able to execute in the operational environment of the combat system as
described in the description. The software must be evaluated against
Government-provided test scenarios. The demonstration will take place at a
Government- or company-provided facility. Provide software design descriptions
(SDDs) and test plans/procedures to demonstrate the product meets the
attributes described in the description. Prepare a Phase III development plan
to transition the technology for Navy use and potential commercial use.
PHASE III DUAL USE
APPLICATIONS: Support the Navy in system integration of the prototype software
application for wave clutter to allow further experimentation and refinement.
The implementation will include incorporation into AEGIS baseline testing and
modernization processes and demonstration that the prototype is fully
functional. This will consist of integrating into a baseline definition,
incorporation of the baselines existing and new threat capabilities, validation
testing, and combat system certification. AEGIS Baseline 9 and 10 combat system
configurations will be the primary focus for integration activities.
