外形隐身技术在国内外研究与应用领域拥有大量的实验验证与实践应用。本文主要讨论了基于电磁波绕射原理的无限长圆柱体隐身实现方法,并对隐身效果进行讨论。综合讨论了外形隐身对于特定结构实现降低雷达散射截面(RCS)的方法,文章进而分析结构的S参数进行验证,并简要分析其可能的原理与实现方法。改变结构后仍然能够产生隐身效果,中心频点会降低。最后分析新型结构能够减小相应的电尺寸的原因。
Shape stealth technology in the field of research and applications at home and abroad have a large number of experimental verification and practical application. This article mainly discusses the method of realizing the infinite cylinder stealth based on the principle of electromagnetic wave diffraction and discusses the effect of stealth. This paper discusses the method to reduce the RCS of a given structure by using profile stealth. The article further analyzes the S parameters of the structure and verifies the principle and implementation of the method. After changing the structure can still produce a stealth effect, the center frequency will be reduced. The final analysis of the new structure can reduce the size of the corresponding reasons.
