The invention proposes that the weapon barrel or the firing barrel (1), or the muzzle brake (3) be used as a waveguide which, however, is operated below the cut-off frequency of the relevant waveguide mode (TE; TM). The transmission coupler (6, 10.1, 11.1) relevant waveguide mode. An oscillator (4) generates the signal which is then passed to the transmission coupler. The waveguide and the projectile (2) form a system in which the electromagnetic field at the reception coupler (7, 10.2, 11.2) is influenced by the position of the projectile (2). The characteristic rate of change of the intensity of the electromagnetic field at the location of the reception coupler (7, 10.2, 11.2), which results from the change in the distance between the projectile (2) and the reception coupler (7, 10.2, 11.2), is measured and is used to determine the muzzle velocity (V0) .
L'invention propose d'utiliser le tube d'une arme ou le tube de tir (1) ou le frein d'embouchure (3) comme conducteur creux qui est cependant utilisé en dessous de la fréquence limite du mode (TE; TM) du conducteur creux concerné. Le coupleur d'émission (6, 10.1, 1 1.1) active le mode de conducteur creux concerné. Un oscillateur (4) crée le signal qui est ensuite envoyé au coupleur d'émission. Le conducteur creux et le projectile (2) forment un système dans lequel le champ électromagnétique au coupleur de réception (7, 10.1, 11.2) est influencé par la position du projectile (2). La modification temporelle caractéristique de l'intensité du champ électromagnétique à l'emplacement du coupleur de réception (7, 10.2, 11.2) qui résulte de la variation de la distance entre le projectile (2) et le coupleur de réception (7, 10.2, 11.2) est mesurée et utilisée pour déterminer la vitesse de sortie (V0).
