摘要
隐身技术在现代战争中具有很重要的作用,为了在未来战争中获得主动权,各国都非常重视飞行器在隐身技术方面的研究与发展。等离子体属于一种新颖隐身技术,它是实现雷达隐身的一种新途径,是雷达隐身技术的最新发展。论述了等离子体隐身的基本原理。通过理论分析和数值模拟,计算了电磁波在等离子体中的反射、吸收衰减与等离子体碰撞频率、电磁波频率的关系,并对实现等离子体隐身进行研究,结果表明,利用等离子体对雷达波隐身是可行的。
Stealth technology has very important effect in modem war. In order to gain the initiative in the future war, many countries are thinking much of the study and develop on aircraft stealth technology. The plasma is a kind of novel stealth technology, is a new approach of radar stealth , and is the newest development of radar stealth technology. In the paper, the basic theories about plasma stealth are described. The relations between reflection, absorption attenuation of electromagnetic waves in the plasma and the plasma collision frequency as well as the electromagnetic frequencies are studied by theory analysis and numerical simulation. Moreover we discuss the plasma stealth implementation. The result shows that using the plasma for radar wave stealth is a feasible method.
