Radar and wind turbines: A guide to acceptance criteria

A wind turbine placed in the vicinity of a primary radar system (PSR) can impact the performance of that system. This paper discusses criteria by which wind turbine placement can be assessed. The effects considered are desensitization overhead and shadowing. The criteria have been implemented in a wind turbine acceptance program that is going to be applied in The Netherlands. We discuss adverse effects that wind turbines placed in the vicinity of a PSR may have on the radar performance, as well as mitigating measures. Subsequently, the models used to assess the influence of the wind turbine are described.
