• Depth Determination Accuracy of the Modified Prony Method in a Swath Mapping Application

  Publication

  • P. Grall
  • J. Marszal

  - Year 2018

  This article presents the performance of the modified Prony method in a swath mapping application. Depth determination accuracy is assessed by processing raw signal acquired by an EdgeTech 6205 swath bathymetry system over flat seafloor. An updated version of the method, proposed previously by the authors, is used to determine the number of signal echoes. The number of signal echoes is essential for performing the low-rank approximation...

• The accuracy of a new approach to order determination for the Modified Prony method in swath mapping application

  Publication

  • P. Grall

  - HYDROACOUSTICS - Year 2017

  This article presents the performance of a new approach to determine the model order for the modified Prony method applied to swath acoustic mapping. Key requirements for any mapping application are depth determination accuracy and angular resolution. Depth determination accuracy is strictly related to angular accuracy and geometrical relations between receiver and sources of the backscattered signal. Angular resolution determines...

• Theoretical analysis of a new approach to order determination for a modified Prony method in swath mapping application

  Publication

  - HYDROACOUSTICS - Year 2017

  This article presents a new approach to determine the model order (number of principal components) in the modified Prony method applied to swath acoustic mapping. Determination of the number of principal components is a crucial step in the modified Prony method. In the proposed approach the model order is chosen based on the underlying physical model of the underwater acoustic environment, and utilised signal processing operations....

  Istotnym założeniem metody SPS-S jest możliwość stosowania treningu słuchowego w warunkach życia codziennego, a więc także poza gabinetami placówek terapeutycznych. Mobilne urządzenie - stymulator słuchu jest oparte na najnowszej technologii mikroelektronicznej, Oferuje on możliwość wykorzystywania wielu programów terapii, które przebiegają z zastosowaniem algorytmów cyfrowego przetwarzania dźwięku. Algorytmy te można podzielić...

  - RELIABILITY ENGINEERING & SYSTEM SAFETY - Year 2022

  To ensure the risk level associated with continuously increasing maritime traffic through particularly sensitive sea areas remains at acceptable level, a periodic risk assessment needs to be carried out by the relevant authorities. As a part of such assessment, allowing for proactive countermeasures to mitigate risk, the frequency of accidents is estimated along with the assessment of geographical locations where the accidents...
