It is possible to improve the hit probability of programmable projectiles by means of this method. For this purpose a predetermined optimal disaggregation distance (Dz) between a disaggregation point (Pz) of the projectile (18) and an impact point (Pf) on the target is maintained constant by the correction of the disaggregation time (Tz) of the projectile (18). The correction is performed by adding a correcting factor, which is multiplied by a velocity difference, to the disaggregation time (Tz). The velocity difference is formed from the difference between the actually measured projectile velocity and a lead velocity of the projectile, wherein the lead velocity is calculated from the average value of a number of previous successive projectile velocities.

L'invention est une méthode qui permet d'améliorer la probabilité d'atteinte de l'objectif des projectiles programmables. cette fin, la distance de désagrégation optimale prédéterminée (Dz) entre un point de désagrégation (Pz) du projectile (18) et un point d'impact (Pf) sur la cible est maintenue constante par la correction du temps de désagrégation (Tz) du projectile (18). La correction est effectuée en ajoutant au temps de désagrégation (Tz) un facteur de correction qui est multiplié par une différence de vitesses, cette dernière étant la différence entre la vitesse mesurée du projectile et sa vitesse moyenne, celle-ci étant la valeur moyenne des vitesses d'un certain nombre de projectiles précédemment lancés avec succès.
