A broadband technique to reduce the radar cross section (RCS) of complex targets is presented. In such targets, multiple-bounce mechanism dominates their RCS. The proposed technique demonstrates that by treating the multiple-bounce mechanism as a cascaded phenomenon, the problem then simplifies to identifying and implementing a set of orthogonal functions. Robust guidelines for avoiding grating lobes are provided using array theory. The 90° dihedral corner is used to verify the proposed technique. Measurements are reported for a fabricated prototype with artificial magnetic conductor (AMC) technology where a 70% RCS-reduction bandwidth is observed. To generalize the method, a 45° dihedral corner, with quadruple-bounce mechanism, is considered. Generalized guidelines are summarized and applied to reduce the RCS of complex targets using the proposed method.
