Side-scan sonar generates an image based on the reflection of sound waves. The reflection
takes place with the first encountered object, which, in practice, may be a passing fish or …

Determining the altitude of side-scan sonar (SSS) above the seabed is critical to correct the
geometric distortions in the sonar images. Usually, a technology named bottom tracking is …

The Autonomous Underwater Vehicle's body attitude has a great influence on some specific
underwater tasks, such as topographic prospecting, target detection, etc. Therefore, this …

Precision bottom tracking is a core step in the data processing of side scan sonar (SSS),
which is of critical value for the quality of the final SSS production. Currently, the automatic …

In this paper, we propose an algorithm for estimating the beam aperture of the acoustic
transducers by using the geometric backscattering model for side-scan sonar systems. The …

The bottom tracking is to confirm the first bottom return signal in each ping to divide the data
into the seabed area and the water column area, which is an essential part of side-scan …

In light of the prevailing approach in which data from side-scan sonar (SSS) from
Autonomous Underwater Vehicles (AUVs) are primarily processed and visualized post …

Sea bottom line is the echo boundary between the water column and seabed on side-scan
sonar waterfall image. Tracking it correctly is the basis for geometric and radiative correction …

Gate tracking technology plays a crucial role in the autonomous detection of multi-beam
echo sounding. The quality of the tracking algorithm directly impacts the quality of the …

Accurate 3D reconstruction of underwater scenes is very important in various fields related
to underwater operation. Multi-beam bathymetry sonar can be used to reconstruct terrain …
