Abstract

An RCS reduction surface (25) for reducing a radar cross section of an object is described. The RCS reduction surface (25) comprises at least one absorber portion (26, 28), wherein the absorber portion (26,28) is configured to absorb radar waves. The RCS reduction surface (25) further comprises at least one reflecting portion (30), wherein the reflecting portion (30) is configured to reflect radar waves. A first plane (E₁) being associated with a top surface of the absorber portion (26, 28) and a second plane (E₂) being associated with a top surface of the reflecting portion (30) are spaced from each other by a predefined distance (Δd). The predefined distance (Δd) is configured such that radar waves with a predefined wavelength range that are reflected at the absorber portion (26, 28) and at the surface of the reflecting portion (30) interfere destructively with each other. Further, an RCS reduction member (24) and a radar test system (10) are described.
