PyTMatrix-LTE

pytmatrix-lte is a Python package to simulate how particles scatter electromagnetic waves (for example in radar applications).

This project is a maintained update of the original jleinonen/pytmatrix so it works with modern Python versions.

Quick Install

You need:

• Python 3.11 or newer
• gfortran installed on your computer

Install gfortran (example with conda):

conda install -c conda-forge gfortran

Install the package:

pip install git+https://github.com/ltelab/pytmatrix-lte.git

Check that it works:

python -c "import pytmatrix; print(pytmatrix.__version__)"
python -c "import pytmatrix; raise SystemExit(pytmatrix.run_tests())"

Usage

See the usage wiki: PyTMatrix Wiki
