Signal detection optimization for underwater acousticsAdams, Mark D. 02 February 2010 (has links)
<p>The Ocean Environment was explored to determine the
effects of temperature, absorption and leakage on acoustic
propagation. Having modeled the acoustic region, a
cylindrical sonar is evaluated to determine its array gain as
a function of frequency. The Detection Threshold is analyzed
and its impact on signal detectability discussed in detail.
utilizing the Passive Sonar Equation, the sonar's
effectiveness is quantitatively measured as a function of
frequency for a typical noise source. Correlation techniques,
modeled on an IBM PC, are then introduced to improve the
sonar's effectiveness.</p> / Master of Science
