摘要
该文利用数值计算的方法 ,研究了运动飞行器与周围等离子体非稳态非线性相互作用问题 .通过求解非稳态非线性相互作用耦合方程 ,得到了在飞行器远尾区 ,场和密度扰动的分布 .计算结果显示 ,在飞行器的尾区 ,飞行器上的天线系统可以作为调制不稳定性的激发源 ,激发出可探测的密度空洞和电磁孤波 .通过对这种密度空洞和电磁孤波的探测 ,可以跟踪探测隐身飞行器的轨迹 .
In this paper, using the method of numerical simulation, the nonsteady, nonlinear interactions between moving body and plasma have been studied in detail,and the distributions of electric field and density caviton are obtained. The results of numerical calculation show that the density cavitons and electromagnetic solitons which can be detected are excided due to the modulational instability. In other words, one could trace out a stealth moving body by means of observing the electromagnetic solitons and the density cavitons.
