TOTS project : Shallow water tomography

***Shallow water tomography : new trends in array processing

Duration : 2010-2013.
Coordinator : Barbara Nicolas (GIPSA-Lab)
ISTerre research team involved : Waves and structures
External collaborations : GIPSA-Lab

Summary
TOTS stands for « Tomographie Océanique en zone peu profonde : nouvelles perspectives en Traitement du Signal » (Shallow water tomography : new trends in array signal processing) and addresses three different problems which can be seen as shallow water acoustic tomography :

  • Sound speed tomography providing the spatio-temporal sound speed structure of a ocean portion,
  • Detection-localization of a target in a shallow water environment, performed from the tomography of the acoustic impedance of the target,
  • Surface tomography whose goal is to retrieve the range-dependent elevation of the ocean surface.
