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.
