High Fidelity RCS Simulation of a Turbine Blade

Radar scattering from a turbine’s moving blades can interfere with Doppler radar systems, producing ghost images.  Understanding the scattering properties of a blade can provide radar manufacturers with the necessary information to mitigate any potential issues.  This study compares the radar cross section of a metal turbine blade, a hollow fiberglass turbine blade, and a hollow fiberglass turbine blade with a metal spar using Remcom's XFdtd EM Simulation Software.
