Electronic Velocimeter.
Abstract
An electronic velocimeter for measuring the muzzle velocity of a projectile employs a conductive coil mounted between the muzzle and an annular conductive shield. The shield and coil are insulated from each other and encircle the trajectory of the projectile. An oscillator means for generating an oscillator signal is coupled to the coil. This oscillator means is responsive to the projectile passing through the coil. A Timing means responds to the oscillator to produce a timing signal. This timing signal represents the transit time for the projectile to traverse a predetermined interval of the trajectory of the projectile. Knowing this transit time the velocity is readily obtained.
