This module computes the backscattering coefficient,
σ
0,
for a given three-scale Gaussian random rough surface, using the I
2EM model.
Various parameters of the rough surface can be specified, such as the
dielectric constant
ϵ =
ϵ' -j
ϵ'',
and the parameters of the
correlation function.
The model is constrained to realistic surfaces; for each scale of
roughness,
( rms height / correlation length ) ≤ 0.25.
