A Gray Scale Correction Method for Side-Scan Sonar Images Considering Rugged Seafloor

IEEE Transactions on Geoscience and Remote Sensing, 2023
Affected by acoustic transmission loss (TL), angular responses of sediments, time varying gain (TVG) residuals, and so on, side-scan sonar (SSS) images have the problem of gray attenuation perpendicular to the track direction.

Bistatic side scan sonar

The Journal of the Acoustical Society of America, 1992
This discloses an improved side-scan sonar capable of locating objects on e ocean floor including the strip directly beneath the sonar transmitter and receiver, which in prior arrangements had to be obtained by another pass. The arrangement includes a platform having acoustic transmitters spaced apart a substantial distance on either side of acoustic ...

Side scan sonar acoustic variability

OCEANS '88. 'A Partnership of Marine Interests'. Proceedings, 2003
The authors report the results of research on the inherent variability of side-scan sonar imagery to determine the magnitude and nature of image intensity fluctuations. Two experiments are presented in which a Klein 100-kHz system is operated under controlled conditions that remove all but purely instrumental and acoustic causes of image variability ...
