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

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 ...
