Windmill clutter mitigation using active meta-surfaces

Windmill clutter mitigation using active meta-surfaces is introduced. The active meta-surfaces are smart metamaterial whose elements are loaded with tunable lumped elements. Using the Gaussian white noise as the control signal, the reflecting signal of the meta-surface would act like noise which makes the radar receiver very hard to detect. The concept and simple simulation are shown to show that the wind turbine clutter can be mitigated and bring no harm to air surveillance radar.
