Computing the influence of wind turbines on RF systems taking into account terrain

The main effects of wind turbines on radars have been described in previous papers [1-3]. They include shadowing by the larger parts and generation of false echoes. Previous studies have been focusing on the influence of moving objects, such as wind turbines, on aeronautical and maritime radars, usually working in the L/S band and in the X-band respectively. Here, we will not only take into account terrain properties, but also compute systems very close to each other and at lower frequencies, where UTD is not valid any more. Also, particular attention will be paid to the computations of systems that are in the near-field of the antenna.
