Study on the impact of bubble curtain on underwater acoustic communication

摘要

Bubble curtain technology has been applied in underwater blasting engineering for decaying the sound wave. Applying it to underwater acoustic countermeasure (UAC) is bound to achieve certain results. So it is important and necessary to assess the effect of bubble curtain on underwater acoustic (UWA) communication. In this paper, we commence from the bubble resonance theory and apply the Bellhop ray model in analyzing the bubble curtain which damps the impact signal at different depths and bubble curtain ranges and verify the correctness of the model. With this method, we get the impact of bubble curtain on underwater acoustic communication based on frequency shift keying (FSK) modulation by simulation and laboratory experiment.
