Spatial coherence of speckle for repeat-pass synthetic aperture sonar micronavigation
(2021-03-31)
Accurate positioning of autonomous underwater vehicles is a major challenge. The long-term drift is problematic if global position updates are not available, and for applications such as repeat-pass interferometry and ...
3D Rendering of Shipwrecks from Synthetic Aperture Sonar
(2021-10-25)
Synthetic aperture sonar (SAS) bathymetric mapping provides centimeter-scale horizontal resolution of the
seafloor. Typically, SAS data has been visualized as 2D images or gridded 2.5D surfaces, but it can also be
plotted ...
