Characterization of non-Gaussian rough surface scattering

In this paper, we examine the scattering properties of rough differently co rrelated surfaces using the IEM model. The effective correlation length of such a surface is pointed out and its effect on the backscattering behavior is discussed. It may be found from the cases considered here that the non- Gaussian effects are very significant even with the same correlation length and height variance. This can be seen From the surface spectra where the r oughness scales are distributed. Among the non-Gaussian correlated surfaces , the exponential correlated has more small scale roughness at the high fre quency components.
