Abstract

New field trials on the EM2040 multibeam echosounder show that the Low Complexity Adaptive beamformer can reduce the main lobe width and sidelobe level simultaneously, avoiding the trade-off with shading for the common Delay and Sum beamformer. Advantages and drawbacks for seabed mapping.

Bio

Tor Inge received his master's in mathematics and physics at the Norwegian University of Science and Technology in 2012. His thesis was done in cooperation with the Norwegian Defence Research Establishment (FFI). Shortly after he started working for Kongsberg Maritime in Horten. Currently he is working on improving the beamforming for the EM2040 multibeam echosounder through a Ph.D. at the University of Oslo.
