等离子体包覆目标RCS可视化计算

The visual RCS computing of coated target with Plasma

本文研究了高频区等离子体包覆目标的RCS可视化计算,将等离子体包覆目标的RCS计算分两部分完成,首先分析电磁波在等离子体中传播的折射衰减及碰撞衰减,将衰减后电磁波利用GRECO算法完成目标RCS计算,与诸如FDTD等数值算法相比,本方法不受目标大小限制,能够快速计算出等离子体包覆目标RCS值,为等离子体隐身技术的工程应用提供了理论参考。

This paper proposes a new method for the visual RCS computing of coated target with unmagnetized plasma. With high- frequency approximation techniques, the method proposed mainly contains two parts： the bending and absorption of the microwaves by plasma is calculated firstly, then the RCS of target is obtained with GRECO method. Compare to other numerical methods, such as FDTD, the main objective of the algorithms presented is obtaining real-time results for arbitrary and very general target shapes with advantages of GRECO method, providing theory reference for the plasma stealth application.
