Generating sounding signals is essential for the operation of active sonar. The system should be highly reliable. This can be achieved through architecture, communication between the devices, and a well-designed and self–testing software. The system presented in the article is responsible for the generation of hydroacoustic sounding signals, and ensures proper interaction between power amplifiers and power supplies. Thanks to its structure, the system ensures a very stable generation of many complex sounding signals in the form of linear or hyperbolic frequency modulated pulses (up or down), continuous transmission wave with increasing frequency and others. It is used in the mine-countermeasure sonar, but can also be used in other types of hydroacoustic systems which require complex sounding signals. The article describes possible technical solutions and sounding signals.
