Abstract
For a spherical acoustic wave incident on a horizontally
stratified ocean bottom, the reflected pressure field and the
plane-wave reflection coefficient are related through a two-dimensional
spatial-wavenumber Fourier transform. An algorithm
is proposed to evaluate the plane-wave reflection coefficient
from the bottom reflected field as a function of angle of
incidencè.
The algorithm is based on the "Projection-Slice" theorem
associated with the two-dimensional Fourier transform. This
technique is implemented to evaluate the plane-wave reflection
coefficient for a perfectly reflecting ocean bottom and for an
isovelocity-low speed ocean bottom model.
