| Abstract: | 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. |
