Challenges of Labelling Unknown Seabed Munition Dumpsites from Acoustic and Optical Surveys: A Case Study at Skagerrak
(2022-05-31)
The disposal of unexploded ordnance (UXOs) at sea is a global problem. The mapping and remediation of historic UXOs can be assisted by autonomous underwater vehicles (AUVs) carrying sensor payloads such as synthetic aperture ...
Modeling the effect of random roughness on synthetic aperture sonar image statistics
(2022-09-02)
A model has been developed to predict the effect of random seafloor roughness on synthetic aperture sonar (SAS) image statistics, based on the composite roughness approximation–a physical scattering model. The continuous ...
Change detection on shipwrecks using synthetic aperture sonar – North Sea Wrecks Task 3.5 Deep Water Case Study
(2022-12-16)
During the last 15 years, synthetic aperture sonar (SAS) technology has matured substantially. Today SAS represents state-of-the-art in seabed imaging and mapping when used on autonomous underwater vehicles (AUV). SAS ...
