The invention relates to a device for measuring the muzzle velocity (V0) of a projectile (6) or similar and to a method that can implement said device. Said device comprises: a weapon barrel or a filling barrel as a wave guide (1), a signal generator (4) that is electrically connected by a signal supply to at least one emission coupler (2) for exciting the weapon or filling barrel (1), and a receiving line for transferring the measured signals of at least one receiving coupler (3) to an evaluation device (5). The distance between the emission coupler (2) and the receiving coupler (3) is variable and can be individually selected according to the selection mode of the wave guide (1). The position of the receiving coupler (3) in relation to the emission coupler (2) depends upon the preferred measuring method. The receiving coupler (3) is disposed between the base of the projectile and the emission coupler (2) if the speed is measured after the projectile (6) has passed, and the receiving coupler (3) is between the tip of the projectile and the emission coupler (2) if the speed is measured (V0) prior to the passing of the projectile (6). When both measuring methods are combined, at least two receiving couplers (3) are integrated and the emission coupler (2) is then placed between both receiving couplers (3). The electromagnetic field of the empty weapon and filling barrel (1) is measured without the projectile (6), in front of the projectile (6) or behind the projectile (6) or in combinations therewith. The muzzle speed (V0) is determined from the measured signals. |
