摘　　要：等离子体隐身是利用等离子体回避雷达探测系统的一种技术。本文介绍了飞机等离子体隐身的原理,提出了一种在飞机机翼封闭前缘内产生离子体的隐身结构设计方案,进而采用CST NWS高频电磁分析软件,对等离子体隐身结构机翼与金属机翼的RCS进行了分析、对比。研究表明,在前缘设置等离子体隐身结构可以改善机翼的总体雷达散射特性。Plasma is one anti-radar stealthy technology applied to aircraft.In the present paper,the plasma stealth principle is introduced,one stealth design scheme with plasma filled in leading edge of wing structures is brought forwards,and the high-frequency electromagnetism software CST is used to analyze the RCS,radar scattering section,for both the stealth wing and metal wing.The study shows that the plasma stealth structure can improve the radar scattering properties of aircraft wing.
