Definitions

  • the invention relates to a method for protecting objects, in particular ships, emitting radiation, in particular IR radiation, against missiles which are equipped with intelligent search heads, in particular scanning, imaging, correlating and / or spectrally filtering search heads, preferably IR search heads , in which by firing a flammable throwing body from a launching tube installed on or near the threatened object, disassembling the throwing body and simultaneously firing and distributing the throwing material in addition to the target in the area of the search optics of the seeker head, an apparent target cloud, in particular infrared - Apparent target cloud, with higher radiation power, in particular infrared radiation power, than the threatened object.
  • intelligent search heads in particular scanning, imaging, correlating and / or spectrally filtering search heads, preferably IR search heads
  • IR search heads in which by firing a flammable throwing body from a launching tube installed on or near the threatened object, disassembling the throwing body and simultaneously firing and distributing the throwing material in addition to the target in the area of the search optics of the seek
  • Such a method with which objects, for example S-boats, can be adequately protected against missiles equipped with infrared guidance seekers under certain circumstances, forms the basis for those described in DE-OS-34 21 734 A1 (see the preamble of claim 1 ) and EP-PS 0 240 819 B1 inventions disclosed. It uses the function of the search heads as follows:
  • the search heads have optics that have relatively large opening angles at the beginning of the so-called search phase, which usually begins at a distance of about 10 to 15 km from the object, so that they have, for example, a search range of about 3000 to 5000 m in azimuth and approximately 300 to 500 m in elevation.
  • the search head switches as the missile approaches the object, which is also referred to as lock-on.
  • the angle of view of the optics of the seeker head is greatly reduced, both in azimuth and in elevation.
  • the area covered by the search window of the search head is then only 100 m in azimuth and about 50 m in elevation. This area then becomes smaller and smaller as the missile approaches to the point of impact.
  • the infrared target cloud to be formed to deflect the missile may therefore only be about 40 to 50 m to the side of the object's center of radiation and only about 25 to 30 m above the boat, so that it can still be seen from the already reduced viewing angle of the optics of the infrared steering seeker head is detected. Furthermore, it must have a significantly higher infrared radiation power compared to the actual object.
  • the conventional method has the disadvantage that there is still no distraction or protection in the time between the launch and the deployment of the dummy target.
  • DE-AS 10 96 805, DE-PS 258 538 and DE 34 21 734 A1 describe projectiles which emit effective energy during the flight in the infrared range, but there are no references to the placement of seekers here.
  • the invention has for its object to improve the apparent target effectiveness of the generic method in such a way that a search head on the object to be protected can be reliably guided away from the object.
  • this object is achieved in a further development of the generic method in that, when the throwing body is fired, a radiation device located in the throwing body is put into operation, which forms a form of energy corresponding to the subsequent apparent target, starting immediately after the launch until the false target is built up, in particular an IR false target , radiates in search head relevant intensity.
  • the radiation device emits continuously.
  • the invention also proposes that the radiation device emits in a clocked manner.
  • further throwing bodies are fired at such a temporal and / or spatial offset, their respective emitting devices are put into operation and, with subsequent ignition and distribution of the throwing means located in them, are disassembled such that one propagates from the previous apparent target cloud Chain of successive further new dummy target clouds, in particular infrared dummy target clouds, is created by those of the respective radiation devices caused energy beam trajectories are connected.
  • the radiation device in the invention can be a pyrotechnic set, e.g. have a gas generator, a flare or a rocket engine.
  • the invention is based on the surprising finding that it is possible to decisively improve the protection effectiveness of the known method by generating a preliminary apparent target in the silhouette of the object to be protected even when the projectile is shot down by means of the radiation device which takes effect immediately, and which produces the rest of the object to be protected outshines and is identified by the seeker head. From this moment on, the search head no longer "sees" the rest of the object to be protected, to which it has already been connected, but the provisional apparent target. As the throwing body moves away from the object to be protected, the search head follows the preliminary apparent target that is moving out of the silhouette of the object to be protected, which is formed by the radiation device in the manner of a tracer ammunition, and is thus reliably guided into the later, final apparent target.
  • the search head can also be deflected if the dummy target e.g. blooms due to poor positioning outside the field of view of the seeker head. This results in a simplification of the self-protection system, the protective effect taking effect immediately after the shot.
  • the drawing consisting of a single figure, shows a search body approaching an object the sequence of the method according to the invention.
  • a controlled missile FK provided with an infrared seeker head, which has located a ship S, initially moves towards the ship S on a flight path F1.
  • a missile is launched from the ship S to be protected along a throw path WB from a position WK1 in the direction of the position of an apparent target SZ.
  • a rocket motor is ignited with the launch of the missile, which continuously emits heat similar to a tracer ammunition, whereby the ship S is already outshone when the missile is fired in position WK1 for the infrared seeker head of the missile FK.
  • the missile FK therefore already targets it in the missile position WK1 and then changes its trajectory continuously from F1 to F2, F3, F4 and F5, while the missile continuously moves through the positions WK2, WK3 and WK4 along the trajectory WB in the direction of the Sham target position SZ, missile position WK5, moves and then forms the sham target SZ, where the missile FK hits the sham target.

Procédé destiné à la protection d'objets, en particulier de bateaux, qui émettent un rayonnement, notamment un rayonnement infrarouge, contre des missiles équipés de têtes chercheuses intelligentes, notamment de têtes chercheuses à scanner, à prise de vues, à corrélation et/ou à filtrage spectral, de préférence de têtes chercheuses à infrarouge, selon lequel un nuage de cible leurre, notamment un nuage de cible leurre à infrarouge émettant un rayonnement plus intense que l'objet menacé, notamment une intensité de rayonnement infrarouge, est engendré à côté de la cible dans la zone de l'optique de recherche de la tête chercheuse par le tir d'un corps de lancement chargé d'une masse de lancement inflammable à partir d'un tube de tir installé sur ou à proximité de l'objet menacé, par la dispersion du corps de lancement, et par la mise à feu et la répartition simultanées de la masse de lancement, caractérisé en ce qu'un dispositif de rayonnement se trouvant dans le corps de lancement est déjà mis en route lors du tir du corps de lancement, lequel commence à émettre immédiatement après le tir une forme d'énergie correspondant à la future cible leurre, et ce jusqu'à la constitution de la cible leurre, notamment de la cible leurre à infrarouge, qui est d'une intensité significative pour la tête chercheuse.
