Interferometric synthetic aperture sonar large scale simulated data benchmark of a ship wreck

open access: yesElectronics Letters, 2023
Interferometric synthetic aperture sonar (InSAS) systems produce high resolution seafloor imagery and 3‐D bathymetry by exploiting the phase differences between image pairs formed from data collected by vertically separated arrays.

An X-Band Radar System for Bathymetry and Wave Field Analysis in a Harbour Area

open access: yesSensors, 2015
Marine X-band radar based systems are well tested to provide information about sea state and bathymetry. It is also well known that complex geometries and non-uniform bathymetries provide a much bigger challenge than offshore scenarios.
