| 摘 要： | 本文详细研究了压缩区内飞行体与等离子体之间的非稳态相互作用，得到了这种相互作用的控制方程。作为辐射源的飞行体天线系统，可以激发出可探测到的电磁弧波。带电粒子密度扰动对电磁弧波的影响表现为一个振幅的衰减因子。这表明，可通过对这种电磁弧波的探测而发现隐身飞行体的踪迹。

| Abstract: | In this paper,non steady interaction between moving bodies and plasma in compression region is investigated in detail and its dominating equations are obtained It is shown that as the radiation source,the radiation from antenna system could excite an electromagnetic soliton The influence on the soliton by density disturbance of charged particles is a weakening factor of amplitude These show that we can trace out a stealth vehicle by mean of observing the electromagnetic soliton |
