Dislocation aspects of wind-turbines within a wind-farm in some distance to primary radar

Wind turbines WT are planned to be constructed often relatively close to radar systems, e.g. air traffic control, air defense, weather radar. The WT are lossless scatterers on the ground and may affect the radar operation in-acceptably. The dislocation in wind-farms is often tried to optimize by a placement on radials of the radar. This scheme is analyzed theoretically and numerically in this paper. It is shown that an optimization is not possible for practical distances of modern WT.
