本文根据反射叠加原理对高精度波导接头的微小反射提出了一种实验研究方法。文中给出了多个相同波导接头叠积反射与单个波导接头反射系数间的近似计算公式。应用本文所提出的方法可利用普通的微波测量系统(如反射仪、驻波测试仪等)对波导接头不连续性所产生的微小反射(反射系数约在.001数量级)进行测量可获得满意的结果和精确度。
In this paper, an experimental research method is proposed for the micro-reflection of high-precision waveguide joints based on the principle of reflection superposition. In this paper, the approximate formulas for calculating the reflection coefficients of multiple waveguide joints with the same waveguide and the reflection coefficients of a single waveguide joint are given. The proposed method can be used to measure the small reflections (reflections of about .001 orders of magnitude) produced by discontinuities in waveguide joints using conventional microwave measurement systems (eg, reflectometers, standing wave testers, etc.) Results and accuracy.
