Abstract

Wind turbines interfere with radar systems due to their large radar cross-section (RCS) and the rotation of the blades. Applying radar absorbing materials (RAM) is considered as a possible mitigation measure. This paper will present RCS modeling results of a generic 40 meters blade. The blade is segmented into 4 sections and the monostatic scattering from each section is modeled. Comparison of the RCS before and after applying the RAM is also shown in this paper. The effect of each section on the total RCS of the blade and the possible impact on the Doppler signature is investigated.
