Abstract:
Locating and surveying underwater dumping sites of unexploded ordnance UXO is challenging, particularly when they are buried beneath the seafloor sediment. Low-frequency LF sonars have a demonstrated capability for detecting buried objects. However, high clutter densities observed in relevant operational environments will limit their use unless a capacity is developed to distinguish between clutter e.g., natural objects, debris, and seafloor topography and UXO. In this project, a two-stage detection approach has been developed for UXO detection. This approach has been applied to MUD-2011 data and the evaluation demonstrated that it is capable of reducing the number of contacts corresponding to natural clutter with 60 compared to a threshold detector.
