DISTRIBUTED
SURVEILLANCE SYSTEMS
Distributed surveillance
systems are networks of sensors that can be spread over
large ocean regions to provide information about the locations
of submarines, surface combatants, commercial ship and fishing
traffic, and even mining and weapons operations. Systems
that are in development use advanced acoustic sensors that
are integrated with state-of-the-art signal processing algorithms.
ESL scientists and engineers have made significant contributions
to the acoustic performance of distributed surveillance
systems and have provided technical leadership in several
key areas:
|
- Acoustic array configurations
- Algorithms for processing and
display of acoustic data
- Adaptive beamforming algorithms
- Acoustic survey
- Mission planning acoustics
|
- Acoustic modeling and performance
prediction
- System engineering
- System design concepts
- Early operational testing
- System Testing
|
ESL improves distributed surveillance
system performance by conducting experimental and modeling
research in acoustics and signal processing. Experimental
work includes at-sea tests with the Shallow Water Acoustic
Measurement Instrumentation (SWAMI) arrays and the Deep
Ocean Survey System (DOSS) arrays. Data from these tests
are analyzed and used as the basis for developing and testing
new detection and tracking concepts. Modeling is done on
a single node level, such as modeling of acoustic propagation,
and at a overall system level, such as modeling the interaction
of a target and distributed surveillance system sensors.
