Abstract : The long term objectives of this work are to establish efficient and accurate signal processing techniques for seafloor remote sensing operations aimed at characterizing the bottom by acoustic methods. This work focuses on acoustic measurements made with a Hydrosweep DS multibeam echo-sounding system installed aboard R.V.M. Ewing. The objectives are to design and implement a data acquisition scheme that preserves base-banded quadrature samples of the output of individual hydrophone staves. (MM)
