Areal seabed classification using backscatter angular response at 95kHz

Thumbnail
Abstract
A sediment classification scheme is developed based on the angular response (AR) of the seabed backscatter strength. The AR is characterised based on its mean level and slope over predefined angular sectors, and the presence or absence of abrupt changes in slope. Because the AR is derived from a finite area a test is performed to recognise the presence of sediment boundaries. The AR curves are shown to provide improved discrimmation over angle invariant methods.
