The Effect of Clustered Scatterers on Volume Reverberation
Abstract
The long term goal of this work is to further the understanding of how clustering in clouds of discrete scatterers has an effect on both forward propagating and backscattered acoustic fields. Clustering is considered to be present when there are spatially dependent correlations in the fluctuating positions of the scatterers. For example, bubble clouds created by oceanic breaking waves have been observed to exhibit clustering at a level that would have a significant impact on the forward propagating acoustic field. Clustering may also be present in fish aggregations (e.g., nearest neighbor distances, school morphologies driven by behavior, inter-school spacing), and should be considered when examining bioclutter. This work is based on a) refining theoretical approaches so that they include clustering; and b) observing clustering in the important classes of discrete volume scatterers in the ocean.
