Definitions

  • the invention relates to a method and a device for protecting a ship from missiles with spectrally filtering IR target seekers.
  • Search heads identify their target based on radiation that distinguishes the ship from its surroundings. More recently, search heads that operate on two frequencies have been used, so-called two-color search heads. These search heads evaluate the IR radiation both in the short-wave range, ie approx. 0.9 to 3 ⁇ m, and in the medium-wave range, approx. 3 to 5 ⁇ m.
  • the ratio of short-wave to medium-wave IR radiation is a characteristic parameter with which a ship can be distinguished very well from apparent targets and the radiation from sun reflections on the water surface.
  • the sun reflection on the water essentially only provides radiation in the region of the short-wave IR, so that the ratio of short-wave IR radiation to medium-wave IR radiation is strongly shifted towards short-wave IR radiation.
  • IR dummy targets fired to protect ships also have short-wave IR radiation.
  • a ship on the other hand, generally has practically no radiation in the short-wave IR range, but emits a lot of radiation in the medium-wave IR range, so that there is a strong shift in the direction of the proportion of medium-wave IR.
  • the "intelligent" search heads can evaluate this shift.
  • DE-OS 32 17 336 describes a method and a device for camouflaging watercraft, in which seawater is pumped up and expelled to form a water curtain that descends outside the ship and shields the areas to be camouflaged.
  • This object is achieved by a method for protecting a ship from missiles with two-color IR target seekers, which is characterized in that an interference transmitter arranged on the ship emits short-wave IR radiation at least at times, the radiation intensity of the interference transmitter being set such that the ratio of shortwave to medium-wave IR radiation is shifted so that the ship is not reliably recognized as a target for the two-color IR seeker.
  • missiles with two-color IR aiming heads can be deflected from an attack on a ship if the ship is provided with a radiation source which emits IR radiation practically exclusively in the short-wave range, since in this way the ratio of short-wave can be shifted so far to medium-wave IR radiation that a seeker head working with two IR frequencies does not reliably recognize the ship as a target.
  • the search head must therefore look for another target that corresponds to the signature given to it. These are, for example, clouds or islands that absorb the incident solar radiation without reflecting it and are therefore self-emitters in the infrared range that have approximately blackbody characteristics. Your IR radiation is therefore in a range that makes it attractive to the seeker as a target.
  • the search head does not find a target, it continues to fly under constant "searches" using inertial navigation and retains its previous kinematic flight curve.
  • the seeker head is removed from the ship in a targeted manner by placing IR false targets in synchronization with the operation of the short-wave jammer.
  • the IR jamming transmitter used according to the invention preferably emits IR radiation in the range from 0.9 to 3 ⁇ m, particularly preferably in the range from 2 to 2.5 ⁇ m, but does not emit in the medium-wave or long-wave IR range.
  • the IR jammer preferably consists of a radiation source which emits in the desired region and is surrounded by one or more filters which are (are) impervious to medium and long-wave IR radiation and / or visible light.
  • a blackbody radiator is used as the short-wave source emitting IR radiation.
  • blackbody radiators are radiation sources that emit radiation that approximately corresponds to the radiation of a black radiator.
  • Blackbody radiators are preferred which have a radiant intensity of at least 80 W / sr in the short-wave IR range. Blackbody radiators, whose radiation is guaranteed in all relevant spatial directions, are particularly preferred.
  • a device is preferably used which consists of a tube, the surface of which can be heated to a temperature of approximately 900 to 1100 ° C. In this temperature range, the radiation maximum of the tube is in the short-wave IR range.
  • the tube can be made of metal, ceramic or quartz, for example.
  • the heatable tube is preferably surrounded by a jacket made of normal optical glass.
  • the glass jacket is located at such a distance from the tube that the glass does not melt.
  • a red filter is arranged around this blackbody radiator, which filters out the visible radiation in the range of up to approximately 900 nm, so that the device does not emit any other rays which could offer a target for the target seeker or in another way could alert the ship.
  • the tube can be heated electrically, pyrotechnically or also via a gas burner.
  • the surface of the tube can have a V-shaped structure or a hexagonal funnel structure.
  • thermal radiators with correspondingly high radiation levels in the short-wave infrared range, such as, for example, can be used as IR radiation sources instead of a blackbody radiator.
  • IR radiation sources instead of a blackbody radiator.
  • a pyrotechnic incendiary agent is used as the short-wave IR radiation emitting radiation source, which has a very high radiation intensity in the short-wave IR range.
  • known IR mock targets are particularly preferably ejected, the burning duration and radiation intensity curve of which corresponds to that of the pyrotechnic incendiary device and the radiant intensity in the medium- and long-wave infrared is higher than that of the ship to be protected.
  • the burning time and radiance of both the pyrotechnic incendiary charge and the IR apparent target can be optimally adjusted using radiometer measurements.
  • the IR apparent target is a more attractive target than the ship for the two-color seeker head, due to the ratio of short-wave to medium-wave IR radiation.
  • Pyrotechnic incendiary devices which are suitable for this preferred embodiment are known per se. Are suitable for.
  • the short-wave IR emitter emitting IR radiation (FIG. 1) is attached to the ship in such a way that unhindered radiation in all directions is ensured.
  • the radiation source is preferably attached in the vicinity of or directly at the radiation center of gravity of the ship. A preferred location that meets both requirements is the chimney of the ship.
  • the short-wave IR radiation is emitted simultaneously
  • the hull is cooled, which leads to a reduction in medium and long-wave IR radiation.
  • the ship's hull is rinsed with suctioned sea water.
  • the ABC decontamination system installed on all larger ships is suitable for this.
  • the temperature of the hull is adjusted to the temperature of the sea water, which means that the contours between the sea and the ship are blurred for a seeker.
  • the invention further relates to a device for carrying out the described method, which is characterized by a radiation source which emits short-wave IR radiation.
  • a device for protecting a ship from missiles with IR aiming heads which is particularly suitable for carrying out the method according to the invention, is characterized by a tube which can be heated to a temperature in the range from 900 to 1100 ° C. and by a jacket made of normal optical Glass is surrounded, and additionally has a red filter that is opaque to radiation in the range of ⁇ 900 nm.
  • This device is particularly suitable for shifting the ratio of short-wave to medium-wave IR radiation into the short-wave range and thus to reduce the probability of hits for two-color search heads.
  • FIG. 1 A preferred embodiment of the device according to the invention is shown in FIG. 1.
  • a ceramic tube 1 which can be heated to approximately 1000 ° C. and has a surface area of approximately 470 cm 2, is surrounded by a glass cylinder 2, which is made of normal optical glass and is therefore impervious to medium and long-wave IR radiation.
  • the glass cylinder 2 is located at such a distance from the ceramic tube 1 that it cannot melt when the ceramic tube 1 is heated.
  • the glass cylinder 2 is surrounded by a red filter 3, which is opaque to visible radiation in the range below 900 nm is.
  • the ceramic tube 1 is attached to the ship exposed via a rod 4.
  • the ceramic tube 1 is heated via a heating connection 5.
  • the IR jamming transmitter used in accordance with the invention it is possible to provide such a radiation intensity in the short-wave IR range that the ratio of short-wave IR rays to medium-wave IR rays emitted by the ship is shifted into such a range that for one A two-color search head makes it difficult to impossible to differentiate between ship, sun reflections and IR false targets, thereby significantly reducing the likelihood of hits.
  • a method and a device are made available which, with relatively simple means, make it possible to protect a ship from attack by missiles with two-color target seekers.
