Sonar which penetrates bubble clouds
Sonar which penetrates bubble clouds
Man-made active sonar does not operate well in bubbly water. However
dolphins and porpoises not only function effectively in shallow coastal waters, but also at
times generate large bubble fields to assist with catching prey. Possible physics solutions
to target detection in bubbly water are proposed, and the validities of such proposed
acoustical solutions are explored through theory, simulation and experimentation.
Whether the solutions are exploited by cetaceans is uncertain. However the efficacy of the
new methodology in test tanks, and the implications for man-made sonar, are
demonstrated.

Abstract
Man-made active sonar does not operate well in bubbly water. However
dolphins and porpoises not only function effectively in shallow coastal waters, but also at
times generate large bubble fields to assist with catching prey. Possible physics solutions
to target detection in bubbly water are proposed, and the validities of such proposed
acoustical solutions are explored through theory, simulation and experimentation.
Whether the solutions are exploited by cetaceans is uncertain. However the efficacy of the
new methodology in test tanks, and the implications for man-made sonar, are
demonstrated.
