Abstract: In order to meet the target of anisotropy radar cross section (RCS) corner reflector, we design a heterotype polyhedron corner reflector. Through the analysis of electromagnetic scattering characteristics, the structure possesses different electromagnetic scattering characteristics under different incidence directions, having different jamming effects under different threat detection directions, and the maximum RCS can reach 281.84 m². Heterotype polyhedron corner reflector could be deployed in particular arrangement, applied to various scenarios, it will form several false targets around the protected target, disturb radar guided weapon when confronted with danger.
