UNDERSEA
WARFARE
SPL'S EXPERTISE IN UNDERSEA WARFARE PROGRAMS COVERS A BROAD
RANGE OF AREAS including active and passive sensors for both
tactical and surveillance systems. Our technical strengths
include sensor signal and information processing with a strong
emphasis on innovative techniques for detecting, classifying,
tracking, and localizing contacts of interest.
The laboratory has also been active in Fleet support activities
including sonar system and operator evaluation, operator training,
and data collection, reconstruction, and analysis of Fleet
exercises. |
| ACTIVE SONAR. SPL
RESEARCH ACTIVITIES IN UNDERSEA WARFARE ARE ORGANIZED INTO
TWO MAIN RESEARCH GROUPS focusing on active and passive
systems, respectively. Current efforts in the Active
Sonar Group include the development, testing, and refinement
of automated detection, classification, and localization (DCL)
systems for the Navy’s surface Fleet. SPL is a codeveloper
(along with the Naval Undersea Warfare Center) of the Echo
Tracker Classifier (ETC) processing and display system. ETC
is targeted for transition into the Navy Fleet as part of
the AN/SQQ-89 combat system. ETC provides automated detection,
tracking, and classification of contacts of interest. Recently,
SPL prototyped new acoustic displays that enhance the sonar
operator’s interaction with the ETC system. SPL has devised
a portable ETC system that facilitates at-sea testing. This
prototype system has been deployed on numerous Fleet exercises
in order to demonstrate its future capabilities, obtain Fleet
feedback, and collect data. The Active Sonar Group is conducting
research in environmentally adaptive signal and information
processing and multisensor data fusion.
PASSIVE
SONAR. THE FOCUS OF THE PASSIVE SONAR GROUP is on the
development of new passive statistical signal processing
algorithms for detection, localization, and classification
based on an understanding of the physics of the sound-generating
mechanisms. Supporting this signal processing focus is basic
and applied research on structural vibrations and structural
acoustics. Much of the signal processing research focuses
on the areas of higher order statistics and wavelet processing
as applied to both stationary and transient signals.
