The module currently features models of antennas similar to commercial antennas:
|
|
|
|
* Geophysical Survey Systems, Inc. (GSSI) 1.5 GHz (Model 5100) antenna (http://www.geophysical.com)
|
|
* MALA Geoscience 1.2 GHz antenna (http://www.malags.com/)
|
|
|
|
A description of how the models were created can be found at http://dx.doi.org/10.1190/1.3548506.

Module overview
|
|
===============
|
|
|
|
* `antennas.py` is a module containing the descriptions of the antennas.
|

|
How to use the module
|
|
=====================
|
|
|
|
The antenna models can be accessed from within a block of Python code in an input file. The models must be used with cubic spatial resolutions of either 1mm (default) or 2mm.

Example
|
|
-------
|
|
|
|
To include an antenna model similar to a GSSI 1.5 GHz antenna at a location 0.125m, 0.094m, 0.100m (x,y,z):
|
|
|
|
.. code-block:: none
|
|
|
|
#python:
|
|
from user_libs.antennas import antenna_like_GSSI_1500
|
|
antenna_like_GSSI_1500(0.125, 0.094, 0.100)
|
|
#end_python:
