Abstract

In this paper, Acoustic wave time reversal self-focusing in underwater waveguide is studied. The acoustic wave time reversal is theoretically and experimentally investigated in a half-infinite fluid medium and a shallow fluid layer placed on a hard half-infinite solid medium, respectively. The ray approach is adopted to study the acoustic field in theory, and the ultrasonic experiment has been carried out in laboratory to model the underwater waveguide. The quantitative and comparative analyses between the experimental and theoretical results are emphatically carried out. Experiment results are consistent to theoretical ones
