【摘要】 从理论上得到一组在考虑非静态极限下描述空间飞行器远尾区内等离子体与场之间的非稳态非线性相互作用耦合方程,并对其进行数值解,通过采用数值模拟计算方法,表明由于高频包络场的调制不稳定性,会产生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】 Under the nonstatic limit, a set of equations are obtained theoretically, which describe the nonsteady, nonlinear interactions between plasma and field in the wake region of a moving body in space. The numerical calculations are also completed. The simulated results show that the potential solitons and density cavitons are formed due to the modula-tional instability if the envelope of high frequency modulational field is sufficiently intense. There will be important for detecting a disguised moving body.更多还原
