ABSTRACT
The submitted contribution provides one of the possible approaches of evaluating the impact of building windmills (WE) in a given location exerted on the operational parameters of the radio-location system (RLS). For the reason of providing the required coverage the RLS is protected by a protective zone of determined by the distances and height of plains of the protection zone band. If, in the protection zone, there are any obstacles which overlap with the determined planes, then deformation of the RLS coverage in the vertical plane may occur resulting in the loss of radar signal on flying objects.
