9 Claims

1. A method for calculating a bursting point of at least one projectile fired from an air defense gun barrel at a target object, comprising:

measuring a position of the projectile,

estimating a position of the projectile,

estimating a speed of the projectile,

measuring a position of the target object,

estimating a position of the target object,

estimating a speed of the target object,

estimating a trajectory of the target object,

calculating optimal bursting points for the projectile based on the estimated position of the projectile, the estimated speed of the projectile, the estimated position of the target object and the estimated speed of the target object,

communicating the bursting points for the projectile to the projectile.
