Application of electromagnetic modeling in naval vessel plasma stealth technology

对等离子体在实现舰船隐身的作用和效果进行研究。首先,对等离子体隐身技术的基本机理和对电磁波衰减的特性进行分析;然后,研究时域有限差分法的应用特点,并利用这种方法对舰船进行电磁建模分析,给出SAR的计算公式。最后,在此基础上,分析等离子体对电磁波能量的折射和碰撞吸收衰减特性,表明等离子体应用于舰船雷达波隐身是可行的,为进一步研究等离子体技术在舰船隐身领域中的应用提供参考依据。

In this paper, the features and effect of the realization of ship plasma stealth is researched. First of all, we analyses the basic mechanism of the plasma stealth technology and the electromagnetic wave attenuation characteristics of the plasma. Then,the application of finite difference time domain method is researched. The electromagnetic modeling of the ship stealth is analyzed based on the method,and the calculation formula of the SAR is achieved. Finally,we know the plasma technology is used in ship radar stealth is feasible,through analyzing the influence of plasma on wave refraction and collision energy absorption, and provides a reference on further studying the application of plasma technology in the field of ship stealth.
