Abstract

Massive windfarms located in front of high frequency over-the-horizon radar (HF OTHR) receive (Rx) antenna arrays modulate strong backscattered ground clutter returns and re-scatter these modulated returns towards the Rx array. In this paper it is shown that these windfarm modulated returns propagated via a ground wave path can be rejected by the optimum processing in 2D Rx antenna arrays with elevation selectivity. We investigate the efficiency of windfarm interference mitigation in Rx arrays with different 2D geometries and specify an optimum geometry for a particular windfarm location with respect to a given RX antenna array.
