This module computes the bistatic scattering coefficient,
σ
0,
for a given 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'',
the type of correlation function, a few parameters of the
correlation function, and the bistatic angles.
The relative azimuth angle is defined as the scattered azimuth angle
minus the incident azimuth angle.
The model is constrained to realistic surfaces with
( rms height / correlation length ) ≤ 0.25.
