항적에 의한 음향산란신호의 실험적 연구

Abstract

Microbubbles are created in copious quantities in the wakes of ocean vessels and, because of their large acoustical cross sections, are responsible for the scattering acoustical signature of the wake.

The acoustic characteristics of the suspended microbubbles can be used to detect and track the ship wake.

In this thesis, we show that the experimental result performed at Korea Maritime University. It was calculated the volume scattering strength via experimental data. We can investigate the motion and distribution of bubble plume within ship wake via volume scattering strength.
