• Seafloor characterisation using multibeam sonar echo signal processing and image analysis

  Publikacja

  • Z. Łubniewski
  • A. Stepnowski
  • A. Chybicki

  - HYDROACOUSTICS - Rok 2010

  The authors propose the approach to multibeam seafloor characterisation which relies on the combined, concurrent use of two different techniques of multibeam sonar data processing. The first one is based on constructing the grey-level sonar images of seabed using the echoes received in the consecutive beams. Then, the parameters describing the local region of sonar image, namely, the local standard deviation of a grey level, and...
