A new approach is presented to reduce the monostatic radar cross section (RCS) of a metal surface. In this approach, called Polarization Cancelation, the polarization of incident wave is rotated by several angles so that the reflected wave becomes zero in direction of incidence. The characteristics and mechanism of the polarization rotation and RCS reduction are investigated. The presented approach is verified by simulation and measurement results.
