ESTIMATING RANGE DEPENDENT SEDIMENT THICKNESS AND REFLECTION COEFFICIENTS FROM BATHYMETRIC DATA FOR IMPROVED SONAR PERFORMANCE MODELLING

Stender, Dan Henrik Sekse; Søvik, André Adelsten (2019)

Knowledge about the underwater environment is critical to anti-submarine warfare operations in littoral waters. The sonar settings and depth selections can significantly affect the predicted sonar performance. Bathymetry ...
Sonar scattering from the sea bottom near the Norwegian coast

Vestgården, Jørn Inge; Hjelmervik, Karl Thomas; Stender, Dan Henrik Sekse; Berg, Henrik (2017)

High false alarm rates on active sonar systems in shallow waters is a well known problem which may be a limiting factor for the sonar performance. One way to reduce the false alarm rate is through supervised learning and ...
