Description

The relief relates to a command device for the anti-aircraft defense, comprising a general lead computer for continuous communication: · the nolar meeting point coordinates (", ':'',': K) bn b / w the polar coordinates u .; r ,; /., is equivalent to.

Since a i-'lujjzeuges also flies straight ahead with constant orbital velocity for the center of a polar orl coordinate system is not linear revolution equations result and not the angular accelerations and higher derivatives must be determined and evaluated, are newer known command devices for evaluation the viMi is a tracking and location device supplied polar coordinates using a transformation and reverse transformation star equipped, with dt in between, lead in map Coordinates is determined. Such Ilakreehner are universal, i.e. H. for each trajectory consultation applicable.

Fs is also known, however, the entire lead calculation to be carried out in polar coordinates.

In general, the first-mentioned known and commonly used type of hit point determination is used Good hit results in a sufficiently short time, provided that the aircraft to be combated is at all is located in the area of action of the flak. Provided that the aircraft to be combated becomes a direct one Assault breach against an object in the immediate vicinity of the flak position, for example against a carrier ship carrying anti-tank guns. lead well-known command devices too late to usable results. because experience has shown that this phase of the standing flight attack of a flight / tight only a few seconds until his bombs are dropped or his On-board weapons lasts.

The task is therefore based on the task of creating a command device of the type mentioned at the beginning to train that a simpler and faster determination of the polar meeting point coordinates Shooting at an object in the immediate vicinity of the anti-aircraft position in a stinging flight attacking aircraft is possible.

According to the invention, this object is achieved in that the command device additionally comprises a simplified high-speed computer which contains polar meeting point coordinates H ₁ ; r ,; )., with linear extrapolation of the polar position coordinates κ ,,,: »·,„; /.
