Abstract
A experiment was carried out to research high frequency underwater sound propagation with rough surface in shallow water. A wave-maker was used to simulate the sine wave surface with different wavelength, amplitude and cycle in a pool (108m×7m×3.5m). The multiple propagation tracks and the multiple reflections at surface and bottom as well as focusing and defocusing due to reflection from surface waves were measured and analyzed. The accuracy and efficient of experiment are verified by the agreement between the numerical simulation and the analysis results of the measured experimental data.
