TLDR
In this article, the authors apply the full wave approach to rough surface scattering and apply it to composite models of rough surfaces, where the principal distinguishing feature of the individual rough surface is its correlation distance, which can be applied to scattering by rough seas as well as by hilly terrain.Abstract:
The full wave approach to rough surface scattering is applied to composite models of rough surfaces. In this work the principal distinguishing feature of the individual rough surface is its correlation distance. Thus this model can be applied to scattering by rough seas as well as by hilly terrain. It is shown that the full wave approach accounts for both specular scatter and Bragg scattering. The scattering cross section for the composite surface, with two or more roughness scales, is shown to be a weighted sum of the scattering cross sections for the individual rough surface heights. Shadowing effects are accounted for explicitly in the analysis. The full wave solutions satisfy reciprocity, duality, and realizability relationships in electromagnetic theory.read more

TL;DR: In this article, the small-slope approximation (SSA) for wave scattering at the rough interface of two homogeneous half-spaces is developed, which is applicable irrespective of the wavelength of radiation, provided that the slopes of roughness are small compared with the angles of incidence and scattering.

A physical radar cross-section model for a wind-driven sea with swell
S. Durden,J. Vesecky +1 more
TL;DR: In this paper, a new spectrum model for the ocean surface was proposed and the two unknown parameters in this spectrum were determined by fitting it to radar observations, and it was shown that this spectrum combined with two-scale scattering theory can predict much of the observed dependence of the radar cross section on radar frequency, polarization, angle of incidence, and wind velocity at incidence angles in the 0\deg-70\deg range.

On radar imaging of current features: 1. Model and comparison with observations

A new model for sea clutter
TL;DR: In this article, first-order scattering theory is applied to obtain sea clutter cross sections in terms of mean-squared height spectrum of the sea surface, and the results are in remarkably good agreement with observations for vertical polarization at P-, L-, C-, and X -bands.

Backscattering from a Gaussian-distributed perfectly conducting rough surface
TL;DR: In this article, an analytical approach to the problem of scattering by composite random surfaces is presented, where the surface is assumed to be Gaussian so that the surface height can be split (in the mean-square sense) into large and small scale components relative to the electromagnetic wavelength, and a first-order perturbation approach developed by Burrows is used wherein the scattering solution for the large-scale structure is perturbed by the small-scale diffraction effects.
