A Mosaic Method for Side-Scan Sonar Strip Images Based on Curvelet Transform and Resolution Constraints [PDF]

open access: yesSensors, 2021
Due to the complex marine environment, side-scan sonar signals are unstable, resulting in random non-rigid distortion in side-scan sonar strip images. To reduce the influence of resolution difference of common areas on strip image mosaicking, we proposed

Side-Scan Sonar Image Segmentation Based on Multi-Channel CNN for AUV Navigation [PDF]

open access: yesFrontiers in Neurorobotics, 2022
The AUV (Autonomous Underwater Vehicle) navigation process relies on the interaction of a variety of sensors. The side-scan sonar can collect underwater images and obtain semantic underwater environment information after processing, which will help ...

Simulation of side-scan sonar [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1986
Acoustic remote sensing is becoming widespread in oceanographic measurement programs. Acoustic systems for such measurements include seafloor subbottom profilers, inverted echo sounders, tomography systems, and side-scan sonars. Numerical simulation of such systems can provide valuable information for system design and for analysis of data from an ...
