The Dynamic Measurement System of the Projectile Velocity Based on aaser and Wireless Communication Principle

摘要

In this paper 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 depression mechanics of gun muzzle flame. It studies the critical technology of how to overcome the powder gas's optics pollution, depress the flame of gun muzzle, make the components of muzzle bear high-temperature, high voltage, wireless communication and anti-jamming. It creatively designs a multifunction speed detector of gun muzzle which can minish the muzzle flame and insure the enough laser intensity for speed measure, and it adopts the wireless communication had realized the measurement of dynamic speed. Some valuable experimental data was get, thus a sort of new attempt of projectile velocity's dynamic measurement was get.
