Theory of cross polarized power returned from a random surface
TLDR
In this article, the cross-polarization of electromagnetic waves by a statistically rough surface is calculated for a circularly polarized incident wave and a homogeneous dielectric surface with either a Gaussian or an exponential correlation function.Abstract:
Cross polarized power resulting from depolarization of electromagnetic waves by a statistically rough surface is calculated. This is done for a circularly polarized incident wave and a homogeneous dielectric surface with either a Gaussian or an exponential correlation function. The polarized return power is also obtained so that comparison between the two could be made.read more

A noncoherent model for microwave emissions and backscattering from the sea surface
S. T. Wu,A. K. Fung +1 more
TL;DR: In this paper, the effect of small irregularities upon the scattering characteristics of the large undulations is included by modifying the Fresnel reflection coefficients; whereas, the effects of the small irregularities upon those of the normal irregularities are taken into account by averaging over the surface normals of large irregularities, and the same set of surface parameters are employed for a given wind speed to predict both the scattering and the emission characteristics at both polarizations.

Backscattering from an undulating surface with applications to radar returns from the Moon
TL;DR: In this article, the backscattering properties of a smoothly undulated surface are discussed by means of a joint distribution of heights and surface slopes, and it is shown that only those regions which are tilted so as to be normal to the incident radiation are effective in the back scattering.
