Abstract

The paper focus on the problem that a certain type of rapid rate firing gun, which the army equipped, it's muz-zle velocity is difficult to measure. On the basis of summing up the advantages and disadvantages of all kinds of muzzle velocity measurement method, the paper put forward the phase measurement method of muzzle ve-locity, and thus design a muzzle velocity measuring system. First, the paper elaborated the basic principle of phase measurement and comprehensive use of integrated metal close detector CS209A and analog PLL NE564 to build up the speed measurement system hardware. When the projectile pass through the coil that fixed at the muzzle, which has the fixed distance, the two coil which connected with the two CS209A will re-spectively produce different phase of two signals input NE564. Then the NE564 outputs the phase difference signal to the upper computer software which written by the LabVIEW and calculation of projectile muzzle ve-locity. The results show that the speed measurement system is accurate and reliable, and it is suitable for the popularization of the troops.
