Short summary
To investigate the possible interference of wind turbines with terrestrial navigation aids and Radar systems, the signals of these systems have to measured in the air space used by aircrafts or being under surveillance, respectively. From the measurements performed in areas with and without wind turbines the influence of these on the signals of terrestrial navigation and/or Radars can be derived. Drone-based and state-of-the-art electronics were used for the measurements.
