利用等离子体的电磁波反射特性, 等离子体可用于设计反射面天线, 设计了金属抛物柱面天线和发光等离子体抛物柱面天线, 并利用CST仿真软件计算了他们的辐射特性, 分析影响发光等离子体抛物柱面天线辐射和散射性能的关键参数。仿真结果表明, 选取适当等离子体柱间距, 等离子体频率, 碰撞频率, 发光等离子体抛物柱面天线具有和金属抛物柱面天线一样的辐射性能, 同时在等离子体天线工作和不工作时其RCS均比金属天线小, 特别在等离子体不工作时其双站RCS缩减程度大于以往相关文献的设计。

By using the electromagnetic wave reflection characteristics of the plasma, the plasma can be used to design the reflector antenna. A metal parabolic cylindrical antenna and a plasma luminescence parabolic cylindrical antenna are designed. The computer simulation technology (CST) software is used to calculate the radiation characteristics and the key parameters influencing on plasma luminescence parabolic cylindrical antenna radiation and scatter characteristics are analyzed. The simulation results show that selecting appropriate plasma column spacing, plasma frequency and collision frequency, the plasma luminescence parabolic cylindrical antenna has the same radiation characteristic as metal parabolic antenna, at the same time, the radar cross-section (RCS) of plasma antenna in operation and without operation are all smaller than that of the metal antenna, especially in plasma without operation, the bistatic RCS reduces to a greater extent than that of the previous related literature design.
