Abstract

3D FLS is a active sonar that can represent the underwater inside visually in forward direction. We discuss on the decrease of bubbles from breaking waves in 3D FLS frames. In the experiment using the bubbles reduction filter the effect of bubbles was decreased a lot.

3D FLS(Foward Looking Sonar)는 상선등의 앞쪽에서 바다내부와 해저를 시각적으로 표현하는 능동 소나이다. 3D FLS에서 수면파에 의한 수중기포의 영향을 감쇄시키기 위한 방법을 논의한다. 실험으로부터 수중기포 감쇄 필터를 사용하여 수중기포의 영향을 감쇄시킨다.
