| Zusammenfassung |
The World Meteorological Organization (WMO) has repeatedly expressed concern
over the increasing number of impact cases of wind turbine farms on weather
radars. Current signal processing techniques to mitigate wind turbine
clutter (WTC) are scarce, so the most practical approach to this issue is
the assessment of the potential interference from a wind farm before it is
installed. To do so, and in order to obtain a WTC reflectivity model, it is
crucial to estimate the radar cross section (RCS) of the wind turbines to be
built, which represents the power percentage of the radar signal that is
backscattered to the radar receiver.
For the proposed model, a representative scenario has been chosen in which
both the weather radar and the wind farm are placed on clear areas; i.e.,
wind turbines are supposed to be illuminated only by the lowest elevation
angles of the radar beam.
This paper first characterizes the RCS of wind turbines in the weather radar
frequency bands by means of computer simulations based on the physical optics theory and then proposes a simplified model to estimate wind turbine
RCS values. This model is of great help in the evaluation of the potential
impact of a certain wind farm on the weather radar operation. |
