Dynamic Measurement System of Projectile Velocity Based on Laser and Wireless Communication

We design a dynamic measurement system of the projectile velocity based on laser,photo electricity conversion,wireless communication,timing gauge number,SCM interrupt technology and the restraint mechanics of muzzle flame.It studies the critical technology of how to overcome the powder gas's optics pollution,restrain the flame of muzzle,and make the components of muzzle bear high-temperature,high voltage,wireless communication and anti-jamming.It creatively designs a multifunction speed detector of muzzle which can minish the muzzle flame and insure the laser's intensity for speed measurement,and that it adopts the wireless communication realizes the measurement of dynamic speed.Some valuable experimental data were gotten,the results indicate the system can measure the projectile velocity accurately,it provides a new method for projectile velocity's dynamic measurement.
