Self-Training Can Reduce Detection False Alarm Rate of High-Resolution Imaging Sonar

Applied Sciences
Imaging sonar is a primary means of underwater detection, but it faces challenges of high false alarm rates in sonar image target detection due to factors such as reverberation, noise, and resolution.

Dynamic margin contrastive learning for open-set recognition in long-tailed sonar imagery

Scientific Reports
Long-tail distribution and open-set recognition remain significant challenges in sonar image classification. This study introduces Dynamic Margin Contrastive Learning (DMCL), a novel framework that simultaneously addresses both issues through adaptive ...

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.
