Code 10.2: I2EM Backscattering from Multi-Scale Random Surface

Code Name: Multiscale_I2EM_Backscatter.m

Description: Code computes σ0 vvand σ0 hhfor a multiscale Gaussian surface characterized by a correlation function of the form given in Eq. (10.15b).

Input Variables:

  ε = ε' - jε'':    Dielectric constant of the scattering medium (unitless)
  s1:    rms height of first scale (m)
  l1:    Correlation length of first scale (m)
  s2:    rms height of second scale (m)
  l2:    Correlation length of second scale (m)
  s3:    rms height of third scale (m)
  l3:    Correlation length of third scale (m)
  f:    Frequency (GHz)
  Θ:    Incidence angle (degrees)

Output Products: σ0 vv(Θ), σ0 hh(Θ)
