Diving Technology Design in a Mine Countermeasure System. Part II, Reliability

Kłos Ryszard

Polish Hyperbaric Research

2022

nr 2(79)

7--26

The article is another paper in an unintended series on designing the technology of diving. It refers to the elements of the methodology used in the works to develop the technology of using the Mx/O_2-SCR CRABE SCUBA type diving apparatus in the mine countermeasure system as an example. The previous article focused on the impact of the NATO Standardization Organization requirements on the purpose of the main process implemented in the system that constitutes the aforementioned diving technology. The present article discusses the reliability of the process implemented in the system.

Artykuł jest kolejnym z niezamierzonego cyklu dotyczącego projektowania technologii nurkowania. Artykuł odnosi się do elementów metodyki stosowanej przy pracach nad opracowaniem technologii wykorzystania aparatu nurkowego typu Mx/O_2-SCR CRABE SCUBA w systemie wojny minowej, jako przykładu. W poprzednim artykule skupiono się na wypływie wymagań standaryzacyjnych NATO Standardization Organization na cel głównego procesu realizowanego w systemie stanowiącym wspomnianą technologię nurkowania. W tym artykule omówiono niezawodność procesu realizowanego w systemie.

Digital signal processing applied to the modernization of Polish Navy sonars

Marszal J.

Polish Maritime Research

2014

nr 2

65--75

The article presents the equipment and digital signal processing methods used for modernizing the Polish Navy’s sonars. With the rapid advancement of electronic technologies and digital signal processing methods, electronic systems, including sonars, become obsolete very quickly. In the late 1990s a team of researchers of the Department of Marine Electronics Systems, Faculty of Electronics, Telecommunications and Informatics, Gdansk University of Technology, began work on modernizing existing sonar systems for the Polish Navy. As part of the effort, a methodology of sonar modernization was implemented involving a complete replacement of existing electronic components with newly designed ones by using bespoke systems and methods of digital signal processing. Large and expensive systems of ultrasound transducers and their dipping and stabilisation systems underwent necessary repairs but were otherwise left unchanged. As a result, between 2001 and 2014 the Gdansk University of Technology helped to modernize 30 sonars of different types.
