Abstract
In electronic warfare, the reduction of radar cross-sectional area is the key to target electromagnetic stealth. Based on the study of the structural design technology of phase gradient metasurface (PGM) cells, a novel RCS reduction design method based on the random distribution of reflective PGMs is proposed in this paper. CST studio suite example simulation results show that the RCS of the proposed PGM array has obvious diffuse scattering characteristics, and the RCS is reduced by 40 dB on average for an array of 6*6 PGM cells in the frequency band of 9 ~ 15GHz, which is better than the RCS reduction technology introduced in previous papers.
