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...

Artykuł dotyczy organizacji zobrazowań na monitorach zmodernizowanych w Katedrze Systemów Elektroniki Morskiej a przeznaczonych do poszukiwania min sonarów bocznych z holowanymi nośnikami anten. We wprowadzeniu opisano strukturę takiego sonaru oraz sposób pozyskiwania i charakter odbieranych sygnałów jako podstawę organizowania zobrazowań efektów nasłuchu. Dalej opisano inne czynniki wpływające na organizację obrazów na monitorach...

There is a growing pressure to investigate how to design and build the unmanned underwater vehicles of different types which are devoted towards performing many tasks under the water surface according to the data missions. During the recent years the Department of Ship Design and Subsea Robotics, Faculty of Ocean Engineering and Ship Technology, Gdansk University of Technology designed and built a few types of unmanned underwater...
