| 摘 要： | 研究了空间飞行体在运动过程中，其前端压缩区内飞行体与等离子体的、非稳态相互作用问题，得到了在强天线辐射源高频场作用下的控制方程．通过计算表明，飞行体上的天线可作为调制不稳定性的激发源，在等离子体中激发起很强的电磁孤波．

| Abstract: | In this paper, nonsteady interaction between moving body with antenna system and plasma in region of compression is investigated in detail.The dominant equations describing the interaction under the action of high-frequency field of strong antenna radiation source are obtained'After calculation,it is shown that as a pumping source,the radiation from antenna system of moving body can excites a strong electromagnetic soliton via the modulational instabilities. |
