Patent ID: 8020491

Claim:
A method of defending against airborne assault ammunition, including the steps of: locating the assault ammunition using at least one position-locating device; determining the ballistic coefficient of the assault ammunition via an ascertainment of the air resistance force of the assault ammunition; iteratively calculating the flight path of the assault ammunition utilizing the ballistic coefficient; determining a firing control solution for firing of fragmentation-type defense ammunition; firing said defense ammunition with a weapon having a caliber of at least 76 mm, wherein after said firing step, said defense ammunition is adapted to have a fuse thereof set and/or to be remotely detonated; after said firing step, igniting or remotely igniting said defense ammunition at an ignition time point T Z ; and determining the air resistance force of the assault ammunition relative to mass from the difference between two kinetic enemies of the assault ammunition at two locations, and the distance between these two locations.
