An Image Quality Improvement Method in Side-Scan Sonar Based on Deconvolution
Remote Sensing, 2023 Side-scan sonar (SSS) is an important underwater imaging method that has high resolutions and is convenient to use. However, due to the restriction of conventional pulse compression technology, the side-scan sonar beam sidelobe in the range direction is ...

RV Pelagia Cruise 64PE372, 27 Jun - 11 Jul 2013. Flow dynamics and sedimentation in an active submarine channel: a process-product approach [PDF]
, 2014 Novel technologies are providing new opportunities to study the structure and dynamics of submarine sediment-gravity flows; these flows are the dominant process for transfer of sediment into the deep ocean, but are very hard to monitor due their ...

Earth Surface Processes and Landforms, Volume 49, Issue 13, Page 4485-4505, October 2024.This study examines an offshore sand bank in four dimensions (spatially and temporally) using repeat bathymetric mapping (lidar and multibeam echosounder data) along with geophysical and grain‐size data. Results demonstrate current‐swept features at the seabed, including dunes and sand ribbons that both migrate northwards between 2008 and 2019. Lateral

Clustering Acoustic Backscatter in the Angular Response Space [PDF]
, 2007 Backscatter mosaicking is a necessary step in the analysis and interpretation of sidescan and multibeam sonar records. However, due to limitations intrinsic to the mosaicking technique, backscatter mosaics are restricted in their capacity to ...

Fisheries, Volume 49, Issue 10, Page 454-462, October 2024.Side‐scan sonar (SSS) is a powerful tool that can be used to address many key questions in fisheries science. In principle, SSS uses dual transducers to transmit a narrow‐beam, wide‐angle acoustic signal as the survey vessel transits an area. The intensity of reflected sound is recorded to generate an image mosaic comprised of benthic substrates and ...

The limits of spatial resolution achievable using a 30kHz multibeam sonar: model predictions and field results [PDF]
, 1998 A Simrad EM300 multibeam sonar was used to attempt to resolve small (-5m high) targets in 450m of water. The targets had previously been surveyed using a deeply towed 59 kHz sidescan sonar.
