闭式等离子体隐身技术及等离子体参数的优化

Closed-plasma Stealthy Technique and Optimization of the Plasma Parameters

提出了一种等离子体隐身技术,即闭式等离子体隐身技术,从而解决了开放式的等离子体隐身技术的诸多问题。通过计算入射到覆盖闭式等离子体的金属平板上的电磁波的反射率,得出了在低温下,提高等离子体密度和温度,有利于更好的吸收电磁波结论。最后计算了未覆盖与覆盖闭式等离子体导体圆锥的雷达散射截面,结果表明:采用闭式等离子隐身技术有很好的隐身效果。

A plasma stealthy technique, the closed-plasma stealthy technique, is provided in this paper. The technique solves some problems of opened-plasma stealthy technique. The reflectivity of incident electromagnetic waves in metal plane with the closed-plasma is computed. The results show that it can absorb more electromagnetic waves in low temperature when its density or temperature is improved. Finally the radar cross section（RCS） of the conducting cone with the closedplasma coated is computed. The results show the closed-plasma stealthy technique is a good one.
