eadf 0.4.1

Effective Aperture Distribution Function

Motivation

Geometry-based MIMO channel modelling and a high-resolution parameter estimation are applications in which a precise description of the radiation pattern of the antenna arrays is required. In this package we implement an efficient representation of the polarimetric antenna response, which we refer to as the Effective Aperture Distribution Function (EADF). High-resolution parameter estimation are applications in which this reduced description permits us to efficiently interpolate the beam pattern to gather the antenna response for an arbitrary direction in azimuth and elevation. Moreover, the EADF provides a continuous description of the array manifold and its derivatives with respect to azimuth and elevation. The latter is valuable for the performance evaluation of an antenna array as well as for gradient-based parameter estimation techniques.

Instructions

Installation

Currently we simply have a source only distribution setup. To install the latest tagged release just use pip install eadf. Otherwise you can simply run pip install -e . --user in your local git clone to get a development setup running.

Documentation

We also have recent documentation on readthedocs. Locally you can build it your git clone via python setup.py build_sphinx -E.

Contributing

We are always happy about unhapppy users, who run into problems, report bugs, file pull requests or cheer for our nice package. If you want something merged, please create a pull request against devel and we are happy to review them.
