Small object detection in side-scan sonar images based on SOCA-YOLO and image restoration
Although side-scan sonar can provide wide and high-resolution views of submarine terrain and objects, it suffers from severe interference due to complex environmental noise, variations in sonar configuration (such as frequency, beam pattern, etc.), and ...

Simulation of side-scan sonar [PDF]
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 ...
