Code 11.1: S2RT/R Backscattering from Rayleigh Layer with Diffuse Upper Boundary

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
