The Effect of Internal Wave-Related Features on Synthetic Aperture Sonar
Hansen, Roy Edgar; Lyons, Anthony P.; Sæbø, Torstein Olsmo; Callow, Hayden John; Cook, Daniel A. (2015)In October 2012, the Centre for Maritime Research and Experimentation (CMRE, La Spezia, Italy) conducted trials from the NATO research vessel (RV) Alliance, off Elba Island, Italy. During this trial, data were collected ... -
The impacts of scene stability and acoustic backscatter coherence on automated seabed change detection
Shouldice, Emma; Smith, Sonja; Sæbø, Torstein Olsmo; Crawford, Anna M; Midtgaard, Øivind; King, Jonathan; Johnson, Shawn F; Sternlicht, Daniel D.; Penko, Allison; Lyons, Anthony P.; Bakken, Erik Makino (2023-09)Practical implementation of long-term seabed monitoring for civilian and military activities requires automated tools for detecting temporal seabed changes, such as for detection of new trawling activities or mine-like ... -
Measurements of high-frequency acoustic scattering from glacially eroded rock outcrops
Olson, Derek R.; Lyons, Anthony P.; Sæbø, Torstein Olsmo (2016)Measurements of acoustic backscattering from glacially eroded rock outcrops were made off the coast of Sandefjord, Norway using a high-frequency synthetic aperture sonar (SAS) system. A method by which scattering strength ... -
Modeling the effect of random roughness on synthetic aperture sonar image statistics
Lyons, Anthony P.; Olson, Derek R.; Hansen, Roy Edgar (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 ... -
Quantifying the negative impact of breaking internal waves on interferometric synthetic aperture sonar
Hansen, Roy Edgar; Lyons, Anthony P.; Cook, Daniel A.; Sæbø, Torstein Olsmo (2018)
