Numerical 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 کاملA rough-surface scattering function for Titan radar studies
[1] Numerous studies show a relationship between radar backscattering and surface roughness. While estimating the statistical properties of small-scale topography is of particular interest for geologic analysis of Cassini radar data, there is no analytic description of radar scattering over a wide range of incidence angles and roughness. This paper presents an empirical function that links the ...
متن کاملA Two-scale Model for Composite Rough Surface Scattering
A new two-scale model is proposed for wave scattering from a composite surface. For each single scale surface roughness, we use a weighted sum of the newly developed statistical integral equation model and the second-order small slope approximation. With these two unifying models collaborating at each scale, this proposed compound model may capture the actual scattering mechanisms and lead to m...
متن کاملThe Pml for Rough Surface Scattering
In this paper we investigate the use of the perfectly matched layer (PML) to truncate a time harmonic rough surface scattering problem in the direction away from the scatterer. We prove existence and uniqueness of the solution of the truncated problem as well as an error estimate depending on the thickness and composition of the layer. This global error estimate predicts a linear rate of conver...
متن کاملRytov Series Approximation for Rough Surface Scattering
A Rytov series approximation for rough surface scattering is presented for an analytical description of the close relation of topographic statistics and topographic scattering. The Rytov series approximation is not subject to the stringent restrictions that apply to the Born series approximation. Numerical calculations of the Rytov series approximation are conducted for several benchmark models...
