Repeating Projectile Velocity Measuring System Based on Laser Screen

Study on measuring repeating projectile velocity and firing rate is an important problem for shooting range test.An area cut velocity measuring system based on four light screens was introduced.Output waveform characteristics of the projectile were analyzed,front edge analysis method were used to conform the characteristic point of output waveform,and signal matching method used to conform the characteristic point of output waveform with vibration signals.A measuring software based on vc＋＋ development environment was programmed,using software to process the waveform date to obtain velocity and firing rate of repeating projectile.The experimental results show that the laser screen measuring system is easy to operate,test results are accurate.
