Abstract:

Active radar stealth technology is an important branch of stealth technology. A quantitative analysis is made about an active radar stealth device. Firstly, the basic Component and working principle of the device 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 device 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 understanding the active radar stealth technology.
