Abstract

In this paper, a novel method for controlling trailing edge scattering is proposed based on tapered periodic surfaces (TPS) loading. The TPS is realized by periodic square metallic patches with tapered dimensions at the direction perpendicular to the considered edge but keeping its period unchanged. The backscattering properties from the trailing edge with the proposed TPS loading are analyzed and compared with that of original trailing edge for various frequencies. It is observed that wide angular radar cross section (RCS) reduction can be achieved and the maximum reduction of mono-static RCS is 25 dB. Furthermore, it is found that the proposed TPS loading can more effectively suppress edge backscattering for a wide range of azimuth angles than the popular trailing-edge serration method.
