Velocity measurement system of projectile and fragment based on virtual instrument

In order to measure the velocity of projectile and fragment, a velocity measurement system for projectile and fragment based on virtual instrument was designed, and systematic composition, measurement principles, hardware and software design were detailed. The function extension of this measurement system could be realized by amending the parameters of instrument panel, and the data processing could be simplified and improved by this measurement system, which made the whole testing process very flexible and convenient.
