Radio Simulations in Python

Collection of scripts over the years simulating radio communications (commericial and amateur radio). Python scripts by Michael Hirsch, Ph.D.

Install

python -m pip install -e .

Usage

Rain Attenuation

ITU P.838 Specific attenuation model for rain for use in prediction methods

considers:

• rain rate [mm/hour]
• frequency [Hz] 1-1000 GHz
• polarization: 0 (horiz) 90 (vertical) or elliptical (degrees)
• elevation angle (degrees)

Show a plot over whole frequency range by setting frequency -1. Show replication of ITU report plots with -v option.

SSB mod/demod

You can use the -e option to introduce a "mistuned" receiver frequency.:
