Method for fire control of an anti-aircraft gun

A method for fire control against aerial targets flying toward a protection object, wherein the position of the protection object is known, the method comprising:

• measuring a measured position of the aerial target,
• estimating a velocity of the aerial target,
• estimating an estimated position of the aerial target,
• predicting a future path of the aerial target from the estimated position of the aerial target and the estimated velocity of the aerial target,
• selecting, from the predicted path, whether the aerial target
• i.) is incoming and thus a threat against the protection object,
• ii.) is passing by and thus not a threat against the protection object, and
• after selecting that the aerial target is incoming:
• setting a model for guidance of the incoming aerial target,
• calculating accelerations to be set by the incoming aerial target to reach the protection object,
• estimating an estimated position of the incoming aerial target,
• predicting a future path of the incoming aerial target from the position of the protection object, the estimated position of the aerial target, the estimated velocity of the aerial target, and the calculated acceleration of the incoming aerial target,
• calculating set-forward points along the predicted path.
