An investigation into the effect of surface waves on time reversed signals in a shallow-water waveguide and the use of chaotic signals for acoustic detection

Abstract

The object of this thesis is to investigate experimentally the effects of surfacewaves on time reversal in a shallow­water waveguide and to use chaotic signals todetect resonant objects. These two areas of research are separate but complementary. Chapters 2 to 4 will explain the background of acoustic time reversal techniques, and the associated experiments performed during this thesis. Chapters 5 and 6 will then focus on chaotic signals, and how they can be used to detect resonant objects underwater. The synergy of these two separate approaches is explored in Chapter 7, which summarises the findings for both areas of research and makes recommendations for further work in these areas.
