摘　　要：主动雷达隐身技术是雷达隐身技术的重要分支。针对一种主动雷达隐身装置进行了深入的定量分析:介绍了该装置的基本组成和工作原理,给出了电磁场约束方程组,在此基础上推导了对消场的表达式,通过对不同入射频率和入射角的数值仿真,着重分析了移相放大器的放大幅度和转移相位对装置隐身性能的影响,并分别给出了放大幅度和转移相位的取值范围。所做工作对进一步认识智能蒙皮式主动雷达隐身技术具有非常重要的理论和工程实践意义。Active radar stealth technology is an important branch of stealth technology. A quantitative ana- lysis is made about an active radar stealth device. Firstly, the basic Component and working principle of the de- vice are described, and then the constraint equations of electromagnetic field is given. Secondly, the cancellation field expression is derived, and then an analysis of phase shift amplifier＇s influence to an active radar stealth de- vice is made, through numerical simulation of different incident frequency and angle. Finally, the values scope of amplitude and phase are discussed. It is very important theoretical and practical significance for further under- standing the active radar stealth technology.
