An Electromagnetic Towed Hydroacoustic Source with a System for Hydrostatic Pressure Control and Compensation

摘要

A hydroacoustic towed emitting system has been developed based on an electromagnetic source with a system of hydrostatic pressure control and compensation. The frequency range of emitted signals is 140–270 Hz, the sound pressure is as high as 3700 Pa, and the depth of immersion is 1–25 m. The system has been designed for carrying out targeted routine investigations in different seasons of the year in shelf water area using a small vessel. The system has been tested successfully.
