Abstract: An RCS reduction surface for reducing a radar cross section of an object is described. The RCS reduction surface comprises at least one absorber portion, wherein the absorber portion is configured to absorb radar waves. The RCS reduction surface further comprises at least one reflecting portion, wherein the reflecting portion is configured to reflect radar waves. A first plane being associated with a top surface of the absorber portion and a second plane being associated with a top surface of the reflecting portion are spaced from each other by a predefined distance. The predefined distance is configured such that radar waves with a predefined wavelength range that are reflected at the absorber portion and at the surface of the reflecting portion interfere destructively with each other. Further, an RCS reduction member and a radar test system are described.
