Assessment of the Shadowing Effect Between Windturbines

Abstract : At VOR or radar frequencies, the field scattered by a windturbine can illuminate nearby windturbines. This depends on the distance between the two windturbines and also on the frequency. This paper proposes an assessment of the shadowing effects between two windturbines at VOR and radar frequencies for typical distances. The interactions between the windturbines is shown to be negligible at VOR frequency while at radarfrequencies, it is not the case.
