Bayesian seabed classification using angle-dependent backscatter data from multibeam echo sounders

Landmark, Knut; Solberg, Anne H Schistad; Austeng, Andreas; Hansen, Roy Edgar (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 ...
A Radon-Transform-Based Image Noise Filter - With Applications to Multibeam Bathymetry

Landmark, Knut; Solberg, Anne H Schistad; Albregtsen, Fritz; Austeng, Andreas; Hansen, Roy Edgar (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 ...
Reducing scalloping in synthetic aperture radar images using a composite image transform

Landmark, Knut; Solberg, Anne H Schistad (2015)

In burst mode SAR imaging, echo intensity depends on the target's azimuth position in the antenna pattern. As a result, an amplitude modulation known as scalloping may appear, particularly in ScanSAR images of ocean ...
