The small slope approximation reflection coefficient for scattering from a "Pierson-Moskowitz" sea surface
Firstand second-order reflection coefficients are presented for the small slope approximation. The first-order reflection coefficient is identical to the Kirchhoff, or physical optics, result, and the secondorder reflection coefficient reduces to those of perturbation theory and the Kirchhoff approximation in the appropriate limits. Numerical results are obtained for acoustic or TE-polarized el...
متن کاملNumerical Studies Of Rough Surface Scattering Models
I have continued to work on the development of theoretical surface scattering models. My objective is to discover or devise a model that accurately predicts scattering from rough surfaces but which also can be used in practical models of acoustic propagation and scattering. In conjunction with this objective, I have been working with another ONR researcher to develop an exact numerical method f...
متن کاملModels for Scattering from Rough Surfaces
Models for scattering of electromagnetic waves from random rough surfaces have been developed during the last two centuries and the scientific interest in the problem remains strong also today due to the importance of this phenomenon in diverse areas of science, such as measurements in optics, geophysics, communications and remote sensing of the Earth. Such models can be categorised into empiri...
متن کاملReflection loss from a "Pierson-Moskowitz" sea surface using the nonlocal small slope approximation
The lowest-order nonlocal small slope approximation (NLSSA) reflection coefficient is derived, and numerical results are presented for one-dimensional (1-D) surfaces, satisfying the Dirichlet boundary condition. Reduction to the perturbation expression occurs in the small height limit, and the first term of the reflection coefficient gives the Kirchhoff approximation (KA) result. Numerical resu...
