This module computes the backscattering coefficient,
σ
^{0},
for a given random rough surface, using the I
^{2}EM model.
Various parameters of the rough surface can be specified, such as the
dielectric constant
ϵ =
ϵ' -j
ϵ'',
the type of correlation function, and the parameters of the
correlation function.
The model is constrained to realistic surfaces with (rms height /
correlation length) ≤ 0.25.
ks is also constrained to be less than 1.
