A three-dimensional, two-way, parabolic equation model for acoustic backscattering in a cylindrical coordinate system

A new PE model for solving three-dimensional, forward and backward sound propagation in a cylindrical coordinate system is presented. The model marches a wave field in the radial direction including the azimuthal diffraction effects, and solves for a backscattered field based on a three-dimensional, single scattering approach. A periodic sidewall boundary condition is applied for computations i...

Sound propagation in a turbulent atmosphere near the ground: a parabolic equation approach.

The interference of the direct wave from the point source to the receiver and the wave reflected from the impedance ground in a turbulent atmosphere is studied. A parabolic equation approach for calculating the sound pressure p at the receiver is formulated. Then, the parabolic equation is solved by the Rytov method yielding expressions for the complex phases of direct and ground-reflected wave...

One-way Wave Equation Modeling in Two-way Wave Propagation Problems

The exact, well-posed, one-way reformulation of Helmholtz-type wave equations and the generalized Bremmer coupling series are applied to the two-way, scalar, multidimensional Helmholtz equation of mathematical physics. These two constructions provide complementary ways of incorporating one-way wave equation modeling into two-way wave propagation problems. The mathematical framework, for the exp...
