Influence of Transmitting Directivity on Underwater Acoustic Communication System

Hong Xu et al.

Summary: In this study, a finite element method was used to establish a model of the broadband longitudinal vibration communication transducer. The relationship between the directivity of the transmitting transducer and the performance of the underwater acoustic communication system was analyzed. Experimental results showed that the directional longitudinal vibration transducer outperformed the horizontal unidirectional cylindrical transducer in reducing multipath effects and bit error rate, thus improving the overall communication performance of the underwater communication system.

The Effects of Manufacturing Inaccuracies in an Underwater Acoustic Projector Array on the Acoustic Interactions

Hoontaek Lee et al.

Summary: Considering manufacturing inaccuracies in underwater acoustic projectors is important for sound navigation and ranging (SONAR) systems. A wave-based distributed mechanical model accurately calculates the changes arising from small variations and can simulate rapid changes occurring near the transducer resonance. It is shown that mutual loading effects between projector units can intensify changes in the presence of manufacturing inaccuracies, with a voltage adjustment method proposed as a solution.
