Synthetic aperture sonar (SAS) interferometry can provide bathymetric maps of the seafloor with high resolution over large swaths. Traditional narrowband interferometry relies on advanced phase unwrapping techniques to resolve phase ambiguities. For wideband systems there are alternative techniques to estimate the absolute (or ambiguity-free) phase(More)
The success of synthetic aperture sonar (SAS) is critically dependent on overcoming several challenges. The sonar has to be positioned with accuracy better than a fraction of a wavelength along the synthetic aperture. The ocean environment, and particularly the sound velocity, has to be accurately estimated for successful focusing of SAS images. For(More)
