改进微波实验中测量驻波比的方法

Improvement of the Method to Measure the Standing Wave Ratio in the Wave Experiment

介绍微波实验中测量驻波比的一种新方法．设计了一个巧妙的测量检波电流的电路，使用该电路可便捷地测量微波的中小驻波比，测量范围宽，且测量精度也有所提高．

This paper introduces a new method to measure the standing wave ratio in the wave experi-ment. A circuit measuring the detected current is designed. By using this circuit, the middle or small standing wave ratio can be measutal convenienily, and the cendnty of measument is improved.
