本文叙述了在50毫米二级轻气炮发射管内采用的微波反射技术:当模型运动的时候,将射入炮管内的微波和从模型上反射的微波间的相位变化记录下来,便可以获得炮管中模型运动速度的连续测量。
This article describes the microwave reflection technique used in the launch tube of a 50mm two-stage light gas gun. When the model moves, the phase change between the microwaves shot into the barrel and the microwaves reflected from the model can be recorded Continuous Measurement of Model Movement Speed in Tube.
