Code 10.1: I²EM Backscattering from Single-Scale Random Surface

Code Name: I2EM_Backscatter_model.m

Description: Code computes σ⁰ _pqfor p,q = v or h for a random surface with a specified correlation function.

Input Variables:

ε = ε^' - jε^'':	Dielectric constant of the scattering medium (unitless)
p:	h or v of receive polarization
q:	h or v of transmit polarization
f:	Frequency (GHz)
Θ:	Incidence angle

Type of correlation function:
(1) Exponential
(2) Gaussian
(3) x-power

Surface parameters:
s: rms height (m)
l: Correlation length (m)
x: power coefficient (for function 3)

Output Products: σ⁰ _vv(Θ), σ⁰ _hh(Θ), σ⁰ _hv(Θ)
