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.

A method for the warding-off of an airborne object approaching a target area through a guidable defensive airborne body intercepting said airborne objects, comprising the steps of: (a) determining and mathematically extrapolating an approach trajectory of the airborne object to said target area through the intermediary of a navigational computer when said object is still at an extremely considerable distance from said target area; (b) determining a spatially and timewise optimized collision point between said defensive airborne body and said airborne object upon launching said airborne body from the vicinity of said target area, determining ahead of said collision point an acutely-angled transient funnel sector about approach trajectory of said airborne object which is tangent therewith at the collision point between said airborne object and said airborne body, and transmitting data thereto and at points along the path for a nominal trajectory for said airborne body for homing into the base of said transient funnel sector prior to the launching of said defensive airborne body; (c) computing in a simulation computer in a time-staggered sequence on board said defensive airborne body subsequent to launching thereof with consideration of a dynamic model of the airborne body which has the nominal trajectory momentarily specified to a superordinated flight controller and position-finding information obtained on board the defensive airborne body relative to an airborne object acquired thereby, a four-dimensional point in space and time of the closest approach by the defensive airborne body which is to be actually expected from the actual conditions of motion to the airborne object which is to be intercepted; (d) iteratively repeating said computation with consideration of the actual relative positional data of the defensive airborne body to the airborne object which is to be intercepted, until computed modified trajectory data indicate expectations of a sufficiently close actual approach to the airborne object in a specified relative orientation of the defensive airborne body; (e) varying in the flight controller the guidance inputs for the originally preset and assumed nominal trajectory pursuant to the extent of such corrected trajectory; (f) and repeating the time-staggered iterative preliminary computation of the actually expected collision conditions with the changed trajectory data and the actual relative position-finding information, so as to correlate such data and information with the inputs to the flight controller.
