A method for reflection measurements of High-power Microwave (HPM) antennas excited with overmoded waveguides is proposed and studied systemically. In theory, principle of the method is proposed and the data processing formulas are developed. In simulations, a horn antenna excited by a TE11 mode exciter is examined and its reflection is calculated by CST Microwave Studio and by the method proposed in this article, respectively. In experiments, reflection measurements of two HPM antennas are conducted, and the measured results are well consistent with the theoretical expectations.
提出并系统研究了一种用于测量由过模波导激励的高功率微波(HPM)天线反射特性的方法。理论上,提出了该方法的原理并推导了数据处理公式。在仿真中,研究了由TE11模式激励器激励的喇叭天线,分别通过CST微波工作室和本文提出的方法计算其反射特性。在实验中,对两个HPM天线进行了反射测量,测量结果与理论预期高度一致。
