This module computes the backscattering coefficient,
σ
0,
for a weakly scattering Rayleigh layer with albedo a ≤
0.2. The layer is
The layer is above a ground
surface characterized by the PRISM model with an exponential correlation function.
The dielectric constant of the surface can be specified,
ϵ =
ϵ' -j
ϵ'',
as well as the rms height, frequency,
single-scattering albedo, layer thickness, and the extinction coefficient.
