摘要
根据在短路波导中驻波与频率相关的基本事实,本文利用运动探针在开槽波导上一系列固定位置处的检波电压来拟合驻波图形,实现毫米波的自动测频。文中给出了实施方案,讨论了主要误差修正和取样点的布置原则,并完成了方案模拟实验。
Based on that the stationary wave paltern is related to the operating frequency in the sho-rt-circuited waveguide, the paper proposes a new automalic frequency measurement method in which the pattern is refited by means of the detections of the moving probe along a slotted waveguide at a series of the given locations. In the paper a practicable scheme is designed. The correciion on two main errors is discussed and the simulation experiment is also completed.
