等离子体复合雷达吸波材料的电磁特性
|
摘要
随着现代先进探测技术的不断发展,对隐身技术的要求不断提高.传统的雷达吸波材料隐身技术在6GHz以上微波频段内有较好的隐身效果,而等离子体隐身技术在低频(6GHz以下)更易于实现.基于此,文中采用雷达吸波材料和等离子体技术复合,利用同轴网格辉光放电产生等离子体与雷达吸波材料相结合,并进行了隐身性能测试.测试结果表明,复合隐身效果优于单一隐身技术的隐身效果,且通过调节等离子体的放电功率等参数,易于实现隐身效果的控制.本文的研究工作可以为等离子体和雷达吸波材料复合隐身技术相关研究提供一定参考.
With the development of the modern advanced detection technology,the stealth technology needs to be constantly improved.The traditional stealth technology,radar absorbing material(RAM)has a stealth effect above 6GHz of microwave.However,plasma stealth technology is easier to implement at low frequency(below 6GHz).Based on this,this paper attempts to combine radar absorbing material technology and plasma technology,and use the plasma generated by coaxial grid glow discharge incorporation with the radar absorbing materials,and then test its stealth performance.The results show that the effect of composite stealth is better than that of single stealth technology,and the control of stealth technology is easier to realize by adjusting the parameters such as the discharge power of plasma.The work in this paper can provide some references for the research on the composite stealth technology of plasma and radar absorbing materials.
