Abstract

An apparatus and method for measuring muzzle velocity (V₀) of a projectile, which apparatus includes a smooth weapon barrel or firing barrel as a waveguide, a signal generator which is electrically connected via a signal supply line to at least one transmission coupler in order to energize the weapon barrel or firing barrel, and a receiving line for passing on the signals measured at at least one receiving coupler to an evaluation device. If the velocity is measured after the projectile has passed through, the receiving coupler is located between the projectile base and the transmission coupler, while the receiving coupler is between the projectile nose and the transmission coupler when the velocity (V₀) is measured before the projectile passes through. The electromagnetic field of the empty weapon barrel is measured without a projectile, in front of the projectile or behind the projectile, or in combination. The muzzle velocity (V₀) is then determined from the measured signals.
