Bayesian seabed classification using angle-dependent backscatter data from multibeam echo sounders
(2014)
Acoustical seabed classification is a technology for mapping seabed sediments. Processed multibeam sonar data yield the variation of the seabed scattering strength with incidence angle, and this paper examines the effect ...
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 ...
A Radon-Transform-Based Image Noise Filter - With Applications to Multibeam Bathymetry
(2015)
This paper describes a linear-image-transform-based algorithm for reducing stripe noise, track line artifacts, and motion-induced errors in remote sensing data. Developed for multibeam bathymetry (MB), the method has also ...
Automatic detection of marine gas seeps using an interferometric sidescan sonar
(2016)
There is a significant need for reliable, cost-effective, and preferably automatic methods for detecting and monitoring marine gas seeps. Seeps at the seafloor may originate from natural sources including sediments releasing ...
Low-Complexity Adaptive Sonar Imaging
(2016)
We have studied the low-complexity adaptive (LCA) beamformer in active sonar imaging. LCA can be viewed as either a simplification of the minimum variance distortionless response (MVDR) beamformer, or as an adaptive extension ...
