ARL:UT's
Signal Physics Division (SPD) has some 30 years’ history in projects to
reduce vulnerability of submarines to threat sensor counter-detection.
This work includes reduction of both radiated noise levels and acoustic
target strength.
-
Development,
construction, and operation of the Target Strength Measurement System
(TSMS), a large-scale acoustic measurement system to conduct full-scale
measurements of submarine target strength in the open ocean.
-
Development of sophisticated techniques to analyze and interpret acoustic target strength data. These techniques allow us to:
- Rapidly assess the quality and validity of target strength data on site during a trial.
-
Assess the overall vulnerability of submarines to a variety of active sonar threats.
-
Identify particular features and phenomena contributing to the overall target strength of submarines.
-
Assess the performance of target strength reduction techniques.
SPD
also has a history of involvement in the development of analytic submarine target
strength models, primarily in the validation process. SPD’s experience,
analytical capabilities, and extensive database provide a strong basis
for model development and validation.
