Velocity measuring system of the interception projectile is studied. The position and the time when the projectile pass is recorded through measurement devices consisted of PLC and two transducers. Then veloci- ty of the projectile can be calculated according to the obtained data. The devices designed have many advanta- ges such as simple structure, high precision and can be used to measure high velocity. The experimental results verify its effectiveness.
