Design of a stealth wind turbine

A hybridization method of Geometrical Optics and Physical Optics (POGO) has been developed to calculate the radar cross section (RCS) of electrically large targets. The GO technique takes high order interactions into account while the PO technique allows to get rid of caustics problems. This hybrid technique is well suited to calculate the field radiated by meteorological radars and backscattered by wind turbines. These radars, having to estimate the clouds speed by calculating the Doppler effects, are very sensitive to moving targets as explained in [1].
