Opis:: R&D MTC has began designing and building the next generation wideband Diver Detection Sonar (DDS, with cylindrical multielement piezocomposite transducer. The paper will focus on key features of DDS technology demonstrator, with special attention on technologies of the transducer. The new transducer is designed at the cooperation with the producer of the transducer - Materials Systems Inc. (Littleton, USA), remainder hardware and software solutions are designed in R&D MTC. In this article specific theoretical and technological principles of the wideband cylindrical piezocomposite transducer will be presented. The implementation of the transducer to the wideband Diver Detection Sonar (DDS) will be described. The results of transducer measurements, transmitter modules, matching circuits modeling and examples of application will be also presented.

Opis:: 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.
