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.iii, 82 leavesBTDapplication/pdfenIn CopyrightLD5655.V851 1990.A337Underwater acoustics -- ResearchMaster's projecthttp://scholar.lib.vt.edu/theses/available/etd-02022010-020009/
