Wideband Interferometry in Synthetic Aperture Sonar
(2013)
Synthetic aperture sonar (SAS) interferometry can provide very high resolution images and topographic maps of the seafloor over large swaths. Processing of interferometric data to retrieve reliable depth estimates of the ...
Challenges in Seafloor Imaging and Mapping With Synthetic Aperture Sonar
(2011)
Synthetic aperture sonar (SAS) is emerging as an imaging technology that can provide centimeter resolution over hundreds-of-meter range on the seafloor. Although the principle of SAS has been known for more than 30 years, ...
Wideband Synthetic Aperture Sonar Back Projection with Maximization of Wave Number Domain Support
(2017)
Wideband and widebeam synthetic aperture sonar (SAS) can provide information on the frequency- and aspect-dependent scattering in a scene. We suggest an approach to predict the quality of the sensor data over the available ...
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 ...
A wavelet schrinkage approach to detect candidate point scatterers in synthetic aperture sonar images for resolution estimation
(2023)
Autonomous Underwater Vehicles (AUVs) that are equipped with side-looking synthetic aperture
sonar (SAS) have become a popular asset for efficient high resolution imaging and mapping of the
seafloor. There are situations ...
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 ...
