Sonar-Based Simultaneous Localization and Mapping Using the Semi-Direct Method
Journal of Marine Science and EngineeringThe SLAM problem is a common challenge faced by ROVs working underwater, with the key issue being the accurate estimation of pose. In this work, we make full use of the positional information of point clouds and the surrounding pixel data.

High-Resolution Sonars: What Resolution Do We Need for Target Recognition?
EURASIP Journal on Advances in Signal Processing, 2010 Target recognition in sonar imagery has long been an active research area in the maritime domain, especially in the mine-counter measure context. Recently it has received even more attention as new sensors with increased resolution have been developed ...

Adaptive Beamforming for Active Sonar Imaging.
, 2012 As of today, sonar imaging is the most effective means of documenting the subsea environment. Existing sonar imaging systems generally rely on conventional beamforming methods to form the image. While conventional beamformers are robust and simple, they leave many of the challenges of sonar imaging unresolved.
