A comparison between backscattering coefficients using Gaussian and nonGaussian surface statistics
Abstract
Backscattering coefficients computed using Gaussian and nonGaussian surface statistics are compared. The computations are performed for a class of surfaceheight distributions and surface correlation functions. Results indicate that the coherent component of the scattering coefficient is strongly dependent upon the surfaceheight distribution. The noncoherent component also depends on the surfaceheight distribution and the surface rootmeansquare (rms) slope when the rms surface height is large relative to the incident wavelength. On the other hand, when the surface rms height is moderate or small, the noncoherent component is sensitive mainly to the surfaceheight correlation function.
