Wind Turbine Analysis
Compatibility analysis between fixed, mobile and radar communication systems and wind farms.
As wind turbines continue to increase in size and wind farms further populate the landscape, radio communications interference analysis become imperative. Due to the large size and metallic construction of the wind turbines, they potentially create interference for radar installations in the form of shadowing, target loss, false target generation, multipath, general noise level elevation, and multiple scatterings.
- Estimation of the received signal and interference levels due to reflection on a wind turbine or a wind farm on Fixed (Microwave links), Mobile or Radar systems.
- Analyses of geometrical and radio constraints to respect by a wind turbine facing various types of radars: High and Medium Altitude, Low Altitude, Landing...
The calculations are made in agreements with the current ITU recommendations and European decrees and take into account not only the communication system to be protected but also the geometry of wind turbines (height of the Mast, length of the Blades, RCS, ...). The results can be made of maps, tables, etc.
As wind turbines become commonplace all over the world, the distances between turbines and radar installations shrink. The closer turbines get to radar, the greater is the intensity of interference effects experienced by the radar. In addition to general noise level elevation and complicated multiple scatterings possible within wind farms, turbines cause the formation of shadow regions, the loss of airborne targets, and the creation of false target plots. Thus degraded, the performance of radar may not be satisfactory to guarantee safe air space operation.
