摘要
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 paper describes the microwave reflecting technigueused in the two stages light gas gun tube of diameter 500mm:whenthe model moves,the phase change between the emitting microwave andthe reflecting microwave in the gun tube may be recorded,so the con-tinuous measurement of the model motion velocity in the gun tube canbe obtained.
