Synthetic aperture bathymetry estimation with a multielement array

, 2012
Bathymetric estimation from multiple synthetic aperture sonar (SAS) images is challenging for shallow water environments with low frequencies. This is due to the multipath echoes corrupting the desired direct-path echoes.

Low frequency synthetic aperture sonar for detecting and classifying buried objects

, 2012
Sidescan high-frequency (HF) sonar (i.e., with frequencies higher than 100 kHz) is ideally suited forproviding high-resolution images of the seafloor. However, since sound does not penetrate into thesediment at these frequencies, such systems cannot be ...

Low-Frequency Synthetic Aperture Sonar System for the Detection of Objects Buried in Mud

, 2012
Naval mines, underwater improvised explosive devices (UW-IEDs), and underwater unexplodedordnance (UW-UXO) are concerns for harbour security. In conditions without burial, existingcommercial systems, such as the REMUS unmanned underwater vehicle equipped

Noncoherent Autofocus of Single-Receiver

, 2001
A significant problem in Synthetic Aperture Sonar (SAS) imaging is compensating for unknown errors in the sonar path trajectory. Unknown deviations from the ideal sonar trajectory have the effect of blurring and smearing the sea-floor image.
