Abstract: A method for the warding-off of flying or airborne objects through the intermediary of guidable defensive airborne bodies. The defensive airborne bodies are launched from the surroundings about the target area which is to be protected; triggered by means of a stationary data transfer device, into a nominal trajectory which, at the latest at a previously specified ideal collision point along the approach trajectory of the target object which is to be intercepted at still a considerable distance, enters approximately tangentially into that particular trajectory. For this purpose, such nominal trajectory is provisionally determined by the ground station pursuant to the constructionally specified dynamics of flight of the defensive airborne body, and the measured or, respectively, extrapolated trajectory of the approaching flying object.
