dc.description.abstract	The problem of angular spreading of sound that has undergone multiple boundary scattering (both sea surface and sea bed) in a shallow water channel is discussed. Measurements made of the horizontal spatial coherence along a line array are related directly to the horizontal angular spread. The data are interpreted within the framework of a probability density function (PDF) for angular spread. The multiple-bounce situation is interpreted by convolving PDF's associated with each single bounce, wherein each single-bounce PDF is computed as if the other boundary interaction were replaced by a perfect mirror reflection.
