Progress Report for The Catholic University of America Contract N00014-94-1-0201.

Abstract

The following topics were studied in detail during the report period: 1) Combined volume and surface scattering in a channel, using a modal formulation. 2) Two-way formulation to account for backscattering in a channel. 3) Data analysis to determine vertical and horizontal correlation lengths of the random index-of-refraction fluctuations in a channel. 4) The effect of random fluctuations on the two-f requency coherence function in a shallow channel. 5) Approximate eigenfunctions and eigenvalues for linear sound-speed profiles. 6) The effect of sea-water absorption on scattering in a shallow channel.
