RCS and radar propagation near offshore wind farms

The wind farm impact on marine radars has not been widely reported. Some past publications have touched on the subject but there has been no accurate model in place to readily examine the effects of different farm geometries, tower shapes and turbine sizes. This paper discusses the radar propagation modeling near offshore wind farms including the methods used to model individual turbine mono and bi-static RCS, and the multiple reflections of radar signals within the wind farm. An initial qualitative comparison between the results of the model and measured data is provided.
