Rapid Computation by Wave Theory of Propagation Loss in the Arctic Ocean
A rapid, accurate method was developed of computing propagation loss as a function of range in the ice covered Arctic Ocean. Input parameters to the propagation model are source and detector depth, wave frequency, ice roughness, bottom topography, and the velocity structure as a function of depth in...

A rapid, accurate method was developed of computing propagation loss as a function of range in the ice covered Arctic Ocean. Input parameters to the propagation model are source and detector depth, wave frequency, ice roughness, bottom topography, and the velocity structure as a function of depth in the ice, water, and bottom. Computation is done by direct integration of the exact integral solution of the wave equation derived from a harmonic point source located in a multilayered, interbedded liquid-solid half space. The integration technique, introduced by H. W. Marsh, employs the Fast Fourier Transform for very rapid evaluation of the integral solution. |
