一种主动雷达隐身装置的定量分析

主动雷达隐身技术是目标雷达特征控制技术(也称雷达隐身技术)的重要分支。该文针对美国的一篇关于主动雷达隐身装置(是一种智能蒙皮)的专利进行了深入的定量分析。首先介绍该装置的基本工作原理，给出电磁场约束方程组；其次，推导移相器转移相位与入射波长、入射角以及该装置组成的空间位置关系等因素的定量关系；最后，通过数值仿真分别讨论入射波长、入射角、空间位置关系等因素对该装置隐身性能的影响，并得出一些有意义的结论。

Quantitative Analysis of an Active Radar Stealth Device

Active radar stealth technology is an important branch of target radar signature control technology (which is also called as stealth technology). A quantitative analysis is made for an active radar stealth device mentioned in a United States patent, and the stealth device is one kind of smart skin. Firstly, the basic working principle of the device is described, and then the constraint equations of electromagnetic field is given. Secondly, the quantitative relationship between the transfer phase, incident wavelength, incident angle, spatial relationship and other factors is derived. Finally, the stealth performance influenced by incident wavelength, incident angle and spatial position is discussed by numerical simulation, and some meaningful conclusions are drawn.
