Analiza obrazów sonarowych dla zapewnienia bezpiecznego postoju statku w porcie

Szulc D.

Logistyka

2009

nr 6

CD-CD

W artykule zaprezentowano wykonane rejestracje sonarowe uzyskane za pomocą sonaru stacjonarnego MS 1000. Przeprowadzona analiza zapisanych obrazów dowodzi możliwości detekcji małych obiektów zalegających w basenie portowym a mogących jednocześnie stanowić potencjalne zagrozenie dla cumujących tam statków.

In the following article have been presented sonar images which were registered by stationary sonar MS 1000 type. The conducted analysis of registered images proves the possibility of the small objects detection laid inside the harbour which can posses a potential threat for moored ships.

Acoustic signal processing in passive sonar system with towed array

Raganowicz A., Rudnicki M., Schmidt J.

2008

Vol. 11

329-338

The aim of this document is to introduce acoustic signal processing in passive sonar system with towed array. The concept of the "acoustic signals processing" includes all possible operations on analogue signals such as amplifying, filtering, sampling and most importantly - operations on digital signals obtained in the sampling process. Digital operations executed in the system include: synchronizing, conversion, sorting, creating deflected beams sets, plotting the power density spectrum received signals and imaging the results. Apart from digital signals processing, we focus on reciprocal connections between microcontrollers and processors in which processing is performed. At the end of this document some exemplary imagings of the output are presented, obtained at the marine testing of this system.
