Research of a Technology in Radar Cross Section Reduction of Missile Wing

简述了弹翼电磁散射机理 ,阐述了电磁阻抗匹配的基本原理 ,设计了弹翼前缘阻抗匹配技术方案及其电磁模型。散射特性实验结果表明 ,在 8GHz～ 18GHz内 ,弹翼RCS可降低 6dB～ 12dB ,说明了所设计的电磁阻抗匹配技术方案对降低弹翼雷达截面 (RCS)具有明显的效果。

In this paper, electromagnetic scattering mechanism of missile wing is briefly described, and the basic theory of electromagnetic impedance matching technology is expounded. The electromagnetic impedance matching technology project of missile wing lead edge and its electromagnetic model are designed. The results of electromagnetic scattering characteristic experiments are 6 to 12dB reduction in wing's RCS compared with its basis within frequency from 8 to 18GHz, and this shows that the efforts has obvious effect in radar cross section reduction of missile wing.\;
