摘要: 主動(dòng)雷達(dá)隱身技術(shù)是目標(biāo)雷達(dá)特征控制技術(shù)(也稱雷達(dá)隱身技術(shù))的重要分支。該文針對(duì)美國(guó)的一篇關(guān)于主動(dòng)雷達(dá)隱身裝置(是一種智能蒙皮)的專利進(jìn)行了深入的定量分析。首先介紹該裝置的基本工作原理，給出電磁場(chǎng)約束方程組；其次，推導(dǎo)移相器轉(zhuǎn)移相位與入射波長(zhǎng)、入射角以及該裝置組成的空間位置關(guān)系等因素的定量關(guān)系；最后，通過(guò)數(shù)值仿真分別討論入射波長(zhǎng)、入射角、空間位置關(guān)系等因素對(duì)該裝置隱身性能的影響，并得出一些有意義的結(jié)論。

Abstract: 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.-
