INFLUENCE OF WIND FARMS ON THE EFFECTIVE OPERATION OF GROUND-BASED RADARS

In the current international context, when the airspace must be permanently monitored, Romania, the NATO eastern border, faces new problems regarding the influence of wind farms on terrestrial radars. Near the conflict zone are large wind power plants, which sometimes can interfere with the terrestrial radars. The distance and direction of the monitored object are estimated by evaluating the produced echo. The transmitted radio frequency can be perturbed by a reflective object, such as wind turbine blades, in motion, for some orientations produced by the wind direction. Some elements regarding terrestrial radars, theoretical and experimental aspects, associated with the measurements' results, and a few conclusions are presented, to illustrate the possible influence of wind turbines on the airspace surveillance capacity.
