Determining the Causes of Geological Clutter in Continental Shelf Waters

Abstract

Geological clutter (geoclutter) is the primary problem encountered by active sonar systems operating in shallow water, because geoclutter is typically confused with returns from an intended submerged target, such as a submarine. To develop operational techniques that reduce the level of physical constraints on signal processing algorithms that minimize the impact of clutter on active target detection and localization, it is first necessary to understand the physical mechanisms that cause geological clutter, which is the primary objective of ONR s Geoclutter Program.
