Synthetic Aperture SONAR (SAS)
13.02.2023 von 16:00 bis 17:30
Kaiserstr. 2, 24143 Kiel, D-Aquarium
In order to increase the azimuth resolution of radar or sonar images, the technique of synthetic aperture can be applied. In contrast to radar, this approach is relatively new to sonar.
In this talk, the principle of synthetic aperture sonar (SAS) will be explained and then the processing steps to obtain a focused SAS image will be presented. In addition to the fundamental SAS topics, some of the effects that can be observed in the images and the possibilities of this technique will be covered.
Short CV
Holger Schmalj
ohann is a research scientist in experimental and applied underwater acoustics at the Bundeswehr Technical Center for Ships and Naval Weapons, Maritime Technology and Research (WTD 71) in Kiel. He received his diploma in physics from the University of Kiel in 2000 and his doctorate (Dr. rer. nat) from the University of Hamburg in 2004. From 2005 to 2008 he worked as a scientist in a research project funded by the German Armed Forces at the Research Institute for Underwater Acoustics and Marine Geophysics (FWG) in Kiel. He then changed permanently to FWG and has worked since the integrating of FWG in 2009 at WTD 71. There he is currently responsible for the “High-resolution imaging with sonar” project. His research interests lie in the field of sonar signal processing, in particular with regard to detection of mine-like objects.
