Aiming at the large dispersion of initial velocity of an individual rocket, this paper proposed an active initial velocity storage measuring system for the rocket, which measured the velocity based on the induction signal that produced by the induction coil going through two magnets, and the purpose of measuring velocity independently was realized. Every part and the working principle of the system were introduced. On the basis of the analysis of key technologies, the high-speed sampling module, the triggering and signal processing module were designed. Moreover the correctness of the design was validated by experimentation. The experiments show that the error of the measured velocity is - 0.34 m/s to ＋ 0.26 m/s, the system has high accuracy and high reliability of 100 % which meets the requirements of the initial velocity measuring system.
