Code Name: S2RTR_DiffuseUB.m
Description: Code computes σ0 vvand σ0 hhfor a weakly scattering Rayleigh layer with albedo a ≤ approximately 0.2. The layer is above a ground surface characterized by the PRISM model (Code 10.5).
Input Variables:
ε = ε' - jε'': | Dielectric constant (unitless) | |
f: | Frequency (GHz) | |
s: | rms height of ground surface (m) | |
a: | Single-scattering albedo of Rayleigh layer (unitless) | |
κe: | Extinction coefficient of Rayleigh layer (Np/m) | |
d: | Layer thickness (m) | |
Θ: | Incidence angle (degrees) |
Output Products: σ0 hh(Θ) and σ0 vv(Θ)
Book Reference: Section 11-2.2 and Eq. (11.23) with n = 2
