抑制表面波等离子体天线噪声的激励源研究

内容简介：从系统设计的角度出发,提出了利用数字频率合成技术和功率增益自动控制技术稳定等离子体激励源的频率和功率,从而降低天线噪声、提高等离子体天线性能.实验结果证明了此方法可行性.

Abstract：A new technology combining digital frequency synthesis with power gain automation is put forward to stabilize the output frequency and the power of the plasma excitation source, thus, to reduce the noises and improve the plasma antenna properties. The experimental results prove the feasibility of this method.
