Abstract
This chapter is concerned with gaining information about acoustic targets from ensembles of backscattered acoustic signals. Emphasis is given to backscatter from point targets, such that individual acoustic cross sections are small compared with the cross sectional area of the interrogating sound beam at ranges of interest. Biological scatterers in the ocean usually constitute such point targets and are used here to provide an example of ensemble processing. Such processing calls for the adoption of a model describing aspects of the scattering and the development of processing techniques. The assumptions involved in the model and processing technique used are of central importance. In this description, attention is given to the use of Monte Carlo techniques to evaluate the assumptions employed and the robustness of the techniques described.
