Acoustic signatures of underwater UXO measured by low frequency broadband SAS
conference paper
The remediation of underwater unexploded ordnance (UXO) requires a capability to detect and classify objects on or beneath the seafloor. This can be facilitated partly by use of modern high-frequency imaging sonar. However, this technology is limited in two respects: 1) the high frequencies employed by these systems cannot penetrate into the sediment to detect buried objects; and 2) the operational effectiveness and efficiency is severely limited by a high false alarm rate in cluttered environments. For these reasons, significant research effort is being put into the use of low frequency broadband sonar. In this paper, we demonstrate the latest experimental results from the MUD system. We show SAS images and multi-aspect acoustic colour plots of various objects (including UXO) buried beneath a layer of mud.
