Optimizing Resolution and Uncertainty in Bathymetric Sonar Systems [PDF]
, 2013 Bathymetric sonar systems (whether multibeam or phase-differencing sidescan) contain an inherent trade-off between resolution and uncertainty. Systems are traditionally designed with a fixed spatial resolution, and the parameter settings are optimized to

The high-frequency backscattering angular response of gassy sediments: Model/data comparison from the Eel River Margin, California [PDF]
, 2002 A model for the high-frequency backscatter angular response of gassy sediments is proposed. For the interface backscatter contribution we adopted the model developed by Jackson et al. @J. Acoust. Soc. Am. 79, 1410–1422 ~1986!#, but added modifications to

Incoherent change detection using amplitude sidescan sonar images [PDF]
Proceedings of Meetings on Acoustics, 2012 The automatic detection of temporal changes in sonar images is of high interest for monitoring critical areas as ports or channels used by submarines for instance. This problem is addressed here as incoherent change detection between two sonar passes. To be able to compare two surveys, sonar images have first to be registered to each other.
