Military sonar upgrading methods developed at Gdansk University of Technology

The fast development of electronic technology and digital signal processing methods makes electronic devices, including sonar systems, obsolete very quickly. But because the ships and mechanical components of sonars are operational for a few dozens of years, it makes perfect sense to modernize these devices by using modern components and signal processing methods and overhaul antenna and mechanical systems. The paper presents examples of modernizing sonar systems implemented at Gdansk University of Technology.
