| 摘 要： | 文章介绍了时域有限差分法(FDTD)算法的基本原理和等离子体的Debye模型,分析了等离子体隐身的基本原理.以Von Karman导弹弹头为隐身目标,用3DSMAX建立弹头和等离子体层的三维模型,然后导入到基于FDTD算法的电磁仿真软件XFDTD中,计算了不同等离子体频率和碰撞频率下弹头的后向散射,给出了相应的频率-雷达截面积曲线.最后对仿真结果进行了分析,并总结了等离子体隐身的规律和特点.

| Abstract: | The paper introduced the basic principle of finite difference time domain(FDTD) and the Debye model of the plasma,and then analyzed the cause of plasma stealth.Taking the Von Karman missile warhead as the stealth target,we used 3DSMAX to build 3D models of the warhead and the plasma,imported the 3D models into the software XFDTD,calculated backward scattering of the target with different plasma frequencies and collision frequencies,and drew the charts of frequency-RCS.Finally,simulation results were analyze... |
