Abstract

We describe the design of a hydroacoustic emitting station with an electromagnetic transducer that develops acoustic pressure of up to 2400 Pa (188 dB) reduced to a distance of 1 m from the emitter axis in a frequency range of 420–520 Hz (at the level of –3 dB); it has an operating depth of up to 500 m. The applied technical solutions make it possible to use the station for a wide range of oceanological research, as well as for the construction of navigation systems for underwater vehicles and data transmission via a hydroacoustic channel.

摘要

我们描述了一种带有电磁换能器的水声发射站的设计，该电磁换能器在420-520 Hz的频率范围内，将声压提高到2400 Pa（188 dB），减小到距发射器轴的距离为1 m。 –3 dB）；它的工作深度可达500 m。应用的技术解决方案使得该站可以用于广泛的海洋学研究，以及用于水下车辆导航系统的构建和通过水声通道的数据传输。
