FINITE-AMPLITUDE NOISE, DIFFRACTION OF AN N WAVE BY A CIRCULAR APERTURE, AND VERTICAL PROPAGATION OF FINITE-AMPLITUDE WAVES IN THE OCEAN

摘要

Basic research on finite amplitude sound waves has been carried out during 1973-74. The following three separate projects are summarized: propagation of finite-amplitude noise, diffraction of an N wave by a circular aperture, and propagation of plane waves of finite amplitude in inhomogeneous media with applications to vertical propagation in the ocean.
