Numerical simulation of the effects of bathymetry on underwater sound propagation using three-dimensional parabolic models
(NATO. SACLANTCEN, 1998/03)
Two different three-dimensional parabolic equation (PE) methods are
Impulse response of a layered bottom
(NATO. SACLANTCEN, 1967/01)
Numerical methods are used for the Fourier inversion of the frequency-dependent loss transfer function. Because of the non-zero finite values of the integrand for an infinite high frequency, the asymptotic value is subtracted ...

The sea surface as a random filter for underwater sound waves
(NATO. SACLANTCEN, 1974/06)
In this dissertation the phenomenon of scattering and reflection of underwater sound waves from the sea surface is studied by considering the surface sound channel as a random, time-dependent filter. This filter can be ...
