An invited paper co-authored with Jack Sheehan entitled Ocean Acoustic Field Matching Normal Mode Filtering and Non-Gaussian Sources, was published in the July 1993 issue of the IEEE Journal of Oceanic Engineering. This paper provides a theoretical foundation for the experimental findings that the acoustic field radiated from a large submerged object is a non-Gaussian random process. We develop a link between normal mode filtering and statistical field matching which is new and potentially important for underwater sound analysis. The results can be applied to other forms of acoustic radiation.
