sigma0 package¶
Submodules¶
sigma0.oh_model module¶
-
sigma0.oh_model.
gammah
(eps, theta)[source]¶ Incoherent reflectivity for H-pol.
Parameters: - eps (complex number) – Complex dielectric constant.
- theta (float) – Angle in degrees.
Returns: gammah – Incoherent reflectivity for H-pol.
Return type:
-
sigma0.oh_model.
gammav
(eps, theta)[source]¶ Incoherent reflectivity for V-pol.
Parameters: - eps (complex number) – Complex dielectric constant.
- theta (float) – Angle in degrees.
Returns: gammav – Incoherent reflectivity for V-pol.
Return type:
-
sigma0.oh_model.
sigma0_bare
(theta, eps_low, f_rms, f, eps_top=1)[source]¶ Oh et.al. (1992) surface backscatter calculations
This functions calculations surface backscatter using the Oh et al. (1992) surface model.
References Oh et al., 1992, An empirical model and an inversion technique for rader scattering from bare soil surfaces. IEEE Trans. Geos. Rem., 30, pp. 370-380
Parameters: - theta (float) – incidence angle in degrees
- eps_low (complex number) – complex permittivity of lower medium
- f (float) – frequency in hertz
- f_rms (float) – fractional rms height. rms_height in meters divided by wavelength
- eps_top (complex number, optional) – complex permittivity of upper(incoming) medium
Returns: sigma0 – Surface backscatter.
Return type:
sigma0.skeleton module¶
This is a skeleton file that can serve as a starting point for a Python console script. To run this script uncomment the following line in the entry_points section in setup.py:
[console_scripts] fibonacci = sigma0.skeleton:run
Then run python setup.py install which will install the command fibonacci inside your current environment. Besides console scripts, the header (i.e. until _logger...) of this file can also be used as template for Python modules.
Note: This skeleton file can be safely removed if not needed!

sigma0.skeleton.
fib
(n)[source]¶ Fibonacci example function
Parameters: n (int) – integer Returns: n-th Fibonacci number Return type: int
-
sigma0.skeleton.
main
(args)[source]¶ Main entry point allowing external calls
Parameters: args ([str]) – command line parameter list
-
sigma0.skeleton.
parse_args
(args)[source]¶ Parse command line parameters
Parameters: args ([str]) – command line parameters as list of strings Returns: command line parameters namespace Return type: argparse.Namespace
