Non-Destructive Method for Velocity Estimation of Small Caliber Projectile

This work presents the development of a novel non-destructive approach for the measurement of high-speed small caliber projectiles with desired accuracy level. The velocity of the projectile is computed from the time taken by the projectile to travel a predefined fixed distance between any two locations under observation. The system development mainly encompassed the design and testing of an electronic circuit for processing the optical signals from the primary optical sensors. The system so developed exhibited an accuracy of +/- 1% during the trials with projectiles of different calibers traveling in a velocity band of 390 m/s to 912 m/s.
