Abstract. During the increasing dissemination of renewable energy sources the potential and actual interference effects of wind turbine plants became obvious. Turbines reflect the signals of weather radar and other radar systems. In addition to the static radar echoes, in particular the Doppler echoes are to be mentioned as an undesirable impairment Keränen (2014). As a result, building permit is refused for numerous new wind turbines, as the potential interference can not be reliably predicted. As a contribution to the improvement of this predictability, measurements are planned which aim at the high-frequency characterisation of wind energy installations. In this paper, a cost-effective FMCW radar is presented, which is operated in the same frequency band (C-band) as the weather radars of the German weather service. Here, the focus is on the description of the hardware design including the considerations used for its dimensioning.

Short summary
A cost-effective and universal FMCW radar is developed for the RF characterisation of wind turbine plants. This radar is modular and can be easily adapted for different measurement tasks. A long-term goal is to investigate high-frequency characteristics of wind turbines at different locations by their Doppler spectrum. The results obtained will be used to derive a statistical model.
