Abstract

In order to be able to successfully ward off the threat of a property (14) by a projectile (15) attacking along a flat path (16) even if only a small residual distance remains, the approach path (16) is detected sensory and separated from at least one in the surroundings the property (14) installed launching device (12) at least one defense missile (13) started. Whose starting direction (20) is not oriented to the current location of the threat, but it tends to be relatively close to the property (14), approximately transversely to the current approach path (16), then the projectile (15) head-on into this train (16 ) until the defense warhead (23) in the head-on encounter constellation is ignited with a minimum residual distance.

Description

The The invention relates to a method according to the preamble of claim 1.

To the scenarios of potentially endangered power plants and the like real estate belongs the terrorist attack with ground-to-ground missiles as attack projectiles. by virtue of their low, in intelligent weapons even terrain guided approach lane, especially when starting in not too big Target distance from the terrain coverage out, such attackers are very late, so with little remaining Remaining flight time, elucidated. This requires a rapid and functionally reliable defense reaction to the If necessary, the attacking projectile can effectively fend off the final approach to be able to.

Thus, this threat scenario is not the steep descent of a reentry warhead, as in the DE 41 28 313 A1 described that a defense missile should meet the reentry warhead on a large target distance about the rules of proportional navigation on a collision course. A comparable kinematic situation does not exist if, according to the present scenario, the attacker can only be detected sensory in the last few meters of his approach against the property to be protected. To make matters worse, that the gun to start a defense missile regularly not stationed in the immediate vicinity of the property to be protected and operated. Rather, one or more defensive guns are preferably of the type described in the DE 10 2004 017375.3 is described in more detail, installed off the property distributed on the edge of the surrounding land. However, this requires an unfavorable for the collision course transverse course of the defense trajectory with respect to the approach path of the attacking projectile.

In Recognition of these facts is the present invention technical problem, an effective procedure for Fending off the threat of attacking a property along shallow approach trajectory Projectile even in already close target approximation.

This object is achieved by the feature combination specified in the main claim. After that, the defense missile is launched at the threat approximately transverse to the extension of their current approach path, so roughly with a certain tendency immediately in front of the property to be protected, launched to then turn the attacking projectile "head on" in its approach path Finally, a splitter - or gas pressure warhead with optimal frontal approach between Abwerflugkörper and attacking projectile initiated to deflect or even destroy the attacking projectile.Thus, with regard to the Zündauslösesensorik can be resorted to the technology that has already proven itself for the protection of moving objects, which even with a Abwehrseinrichtung are equipped for the defense missile, which is given from the outset, the "head on" situation of frontal encounter, such as in the DE 100 24 320 A1 described in more detail. In such frontal encounter no proportional navigation needs to be flown, it depends only on the prediction of the expected minimum residual distance; the entire problem of a complex collision course control on a small residual distance is thus bypassed.

to closer explanation the invention and its developments and modifications and their Benefits will be except to the further claims The following description of one in the drawing with limitation the essence is strongly abstracted and not outlined to scale an application of the method according to the invention.

In terrain 11 are several launchers 12 for highly agile maneuverable missiles using front or tail rudders 13 away from a potentially threatened and therefore protected property 14 such as a civil power plant or a military facility installed. The threat is through an attacking projectile 15 given, its approach path 16 comparatively close to ground flat. The approach of an attacking projectile 15 is detected by sensors, in particular of radar devices 17 in the field 11 distributed and one or more of the launching facilities 12 are assigned such that the one in the field 11 available launch facility 12 which provides the best defensive outlook on the current threat.

From this launching device 12 However, in view of the already relatively close approach of the threat, there is no direct, direct combat 18 of the attacking projectile 15 under the sight of a collision point advanced approximately on the principle of the stationary bearing 19 , Rather, the defense missile 13 from the launcher 12 first a starting direction 20 given that tends to be (roughly speaking) relatively close to the threatened property 14 approximately across the current approach path 16 the sen soriously understood threat. Immediately, however, the defense missile pivots 13 self-steering or remote-controlled in a defense trajectory 21 one concentric to the current approach path 16 runs, that is, at least approximately the approach path 16 but corresponds to the approaching movement of the attacking projectile 15 is head-on in the opposite direction, as shown in the schematic diagram of the drawing.

Even if this head-on defense missile 21 not to an immediate collision with the projectile 15 on its approach path 16 inevitably results in a very close mutual approach in the passage of attacking projectile 15 and defense missiles 13 , So as soon as the on-board sensor 22 of the defense missile 13 and / or one of the radar devices 17 in terrain 11 In the course of their tracking operation, the approach to a tendency to detect a minimum distance and thus to the passenger moment sensory, the warhead 23 of the defense missile 13 ignited, so that by the splinter or gas pressure effect the attacking projectile 15 destroyed or at least disturbed or out of its orbit 16 is deflected, bringing the current threat to the property 14 is repulsed.

To the threat of a property 14 through a longitudinally flat path 16 attacking projectile 15 Even with only a small remaining distance to successfully fend off, so according to the invention, the approach path 16 Sensory detected and at least one in the area away from the property 14 installed launcher 12 at least one defense missile 13 started. Its starting direction 20 is not oriented to the current location of the threat, but tends to run relatively close to the property 14 approximately across the approach path 16 then to the projectile 15 head-on into this train 16 turn around until the defense warhead 23 in this head-on encounter constellation is ignited at about minimum residual distance.
