【摘要】 在非静态极限下,理论上研究了空间飞行器近尾区内等离子体与场之间的非稳态非线性相互作用,得到了一组耦合方程,并对其进行数值计算.数值模拟结果表明由于等离子体的调制不稳定性,导致密度空腔和电磁孤波,这对探测隐身飞行器有很重要的意义.更多还原

【Abstract】 Non-steady interactions between plasmas and field in the near wake region of aircraft are investigated in detail.With a non-static limit,a set of equations that describe these interactions are obtained.The results of the numerical simulation show that the cavity of transverse plasmas is excited and density cavity appears when the envelope of plasma becomes sufficiently intensive.This is very important for detecting the moving body with a ’stealth’ characteristic.更多还原
