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 plays a very important role in the modern war. In order to gain the initiative in future wars, all countries attach great importance to the research and development of stealth technology in aircraft. Plasma is a novel stealth technology, which is a new way to realize stealth radar and the latest development of stealth radar technology. Discusses the basic principle of plasma stealth. Through the theoretical analysis and numerical simulation, the relationship between the reflection and absorption attenuation of electromagnetic waves in the plasma and the collision frequency and the electromagnetic wave frequency of the plasma was calculated and the plasma stealth was studied. The results show that using the plasma to stealth the radar wave is feasible.
