A method of fire control against aerial targets traveling towards an object of protection. A position of the object of protection is known. A position of the aerial target is measured. The position of the aerial target is estimated. A velocity of the aerial target is estimated. A model of a guidance law of the aerial target is applied. An acceleration of the aerial target sufficient to hit the object of protection is calculated. A future trajectory of the aerial target is predicted based on the position of the object of protection, the estimated position of the aerial target, the estimated velocity of the aerial target, and the calculated acceleration of the aerial target. Points of aim along the predicted future trajectory are calculated. A fire control system includes at least one sensor for measuring the position of the aerial target as a function of time.

Method of fire control for gun-based anti-aircraft defence

The invention relates to a method of, with a projectile () comprising a reactive charge (), combating an explosive-charged weapon unit (), preferably an enemy shell, so that undesirable harmful effects on the environment are reduced, wherein the projectile () is configured to penetrate the surface () of the weapon unit () upon impact so that a passage () is opened into the explosive () of the weapon unit (), through which passage () the reactive charge (), under the influence of the kinetic energy of the projectile (), is transferred to the explosive () of the weapon unit (). The method can be deemed to be characterized in that the reactive charge (), upon contact with the explosive () of the weapon unit (), reacts and starts a hypergolic reaction with the explosive (). The invention also relates to a projectile () for the said method.
