Sediment classification was demonstrated using the self-noise of an autonomous underwater vehicle (AUV) received on a short towed array. The adopted approach was to separate the direct path and the surface- and bottom-reflected signals. Electrical interference from the source was used to verify source receiver separation. The amplitude ratio of the bottom reflected to the direct path signal levels,...
The shallow ocean is an uncertain, varying, dispersive environment dominated by ambient and shipping noise as well as temperature fluctuations that alter sound propagation throughout creating a large number of environmental variations. The need to develop processors that are capable of tracking these changes while simultaneously providing enhanced signals implies a stochastic as well as an adaptive...
The shallow ocean environment is ever changing mostly due to temperature variations in its upper layers (< 100m) directly affecting sound propagation throughout. The need to develop processors that are capable of tracking these changes implies a stochastic as well as an “adaptive” design. The stochastic requirement follows directly from the multitude of variations created by uncertain parameters...
