Surface integral equation analysis of the electromagnetic interference (EMI) impact of wind turbines on radar systems

Abstract

Wind turbines (WT), as large conducting structures, may disturb the use of radar in civil and military applications. Therefore, an efficient simulation of a radar system in the presence of a WT is required. This paper deals with WT impact to the radar system operation. The formulation is based on the corresponding surface integral equation (SIE), i.e. the electric field integral equation (EFIE) for metallic objects. The solution is carried out using the Boundary Integral Equation Method (BIEM) combined with physical optics (PO). The model aims to account for the rotation of the blades and to ensure corresponding radar cross section (RCS) prediction. Some illustrative computational examples arising from realistic scenarios are given in this paper.
