Research on Projectile Muzzle Velocity Measurement Technology of Antiaircraft Artillery Based on Infrared Region Method

In allusion to the requirement of projectile muzzle velocity measurement for muzzle velocity closed-loop shoot emendation of antiaircraft artillery,the real-time and follow up measurement technology of projectile muzzle velocity of antiaircraft artillery is researched by infrared region method.Two neighbor photoelectricity butts are fixed in the muzzle aftereffect region,the infrared ray shelter effect when projectile flights off from the muzzle is utilized,the time of projectile fly through the two photoelectricity butts is detected,the projectile muzzle velocity can be measured by calculation.It has been proved through ball firing experimentation at outfield that the projectile muzzle velocity in aftereffect region can be measured by the technology in the paper.
