Definitions

  • the invention relates to a method for providing a dummy target body after the introduction of claim 1.
  • IR deception principles are currently used worldwide: Burning off fuel, pyrotechnic active materials with metallic components (e.g. magnesium / polytetrafluoroethylene), pyrotechnic active materials on carrier materials (flares) and "warm clouds", generated by an exothermic chemical reaction. All of these principles have the common disadvantage that they create points in the infrared or, at best, structureless clouds that have nothing in common with the contour and IR signature of a military object. The consequence of this fact is that these deceptive principles against "intelligent" imaging seekers, in particular IR seekers, of the so-called third generation are completely ineffective.
  • the invention has for its object to provide a method of the type mentioned, by means of which objects, such as ships, can be effectively protected against object contour sensitive "intelligent" seekers with spectral differentiation.
  • the invention is based on the surprising finding that it is possible to use a method, which is suitable in principle for all conceivable objects, for protection against imaging target seekers thereby to indicate that in particular computer-controlled under essentially continuous monitoring of the three-dimensional dummy target body active masses, for. B. in the form of rapid-fire ammunition relatively small caliber, so spatially or temporally offset at the location of the dummy target to be assembled for disassembly that the target signature of the object to be protected in "deceptive similarity" for imaging target seekers, such as IR heads, is simulated.
  • Different active masses are preferably used in this way, in this way differently warm surfaces of the object to be protected, e.g. B.
  • an object to be protected such as B. a destroyer, an ammunition transport or the like, with different spectral attractiveness for the target seeker, so that the most realistic simulation of the object to be protected is achieved in this way.
  • the IR signature of the destroyer 10 shown there has a fuselage area with a relatively uniform surface temperature and two "hot spots" in the form of two chimneys 12, 14.
  • FIG. 2 shows that, according to the method according to the invention, a dummy target body 10 'has a "fuselage part" with an essentially uniform surface temperature and two "hot spots" 12', 14 ', corresponding to the chimneys 12, 14 of FIG. 1.
  • the three-dimensional IR apparent target according to FIG. 2 has a specific similarity to the destroyer according to FIG. 1 for an “intelligent” IR seeker head, that the seeker head will attack the dummy target body instead of the destroyer if the overall apparent target is achieved by appropriate beam strengths and / or beam densities etc. is made more attractive to the seeker than the destroyer.
  • Figure 3 shows a destroyer with the conventional dummy target (torch) 11 without an object-like contour, so that this is not the real object, i.e. a third-generation "intelligent" IR seeker head. the destroyer 10 will be preferred.
  • FIG. 4 shows an ammunition transporter 16 with a single chimney 18. Accordingly, there is IR dummy target, shown according to the invention, again according to FIG. 5, a dummy target body 16 'with a single "hot spot"18'.
  • the invention has been explained above on the basis of the exemplary embodiments shown for the most common application, the protection of ships, but designs for other objects are only available in nunition caliber and ammunition composition, each of which must be optimized for the respective contour and spatial-spectral IR signature. differentiate.
  • the specific IR criteria of the object to be protected shape, area size, spatial spectral radiation distribution, movement behavior
  • the radiance of the dummy target body is increased compared to the object in order to represent the more attractive target for the IR seeker head.
  • the faithful, three-dimensional replica also has the advantage that the invention creates a dummy target body, which is effective for all threats and therefore for several simultaneous attacks from different directions.
  • a three-dimensional dummy target can be achieved by the rapid and continuous targeted firing of specific pyrotechnic active substances under the following Realize basic principles: firing sequence with high cadence, e.g. B. with more than three shots / sec., Small caliber, ie approx.
  • a sequence of shots with a high cadence is expedient when carrying out the method according to the invention in order to repair defects in the IR pattern which gradually become extinguished and sink as well as defects in the IR pattern which arise as a result of wind drift, and in order to be able to build up the apparent target as quickly as possible when an IR target seeker approaches.
  • a rate of 3 rounds / sec is required for ships. displayed in order to build up a three-dimensional apparent target with approx. 5 to 7 IR active masses in 2 seconds and to maintain it for the desired period.
  • the higher the cadence the more accurate the IR simulation of the object.
  • Small calibers (approx. 40 mm and smaller) are therefore used in order to be able to produce the shape, the area and the IR target signature as true to detail as possible.
  • small calibers offer the advantage of higher possible firing sequences. In general, the smaller the caliber, the more accurate (resolution) the IR replica of the object becomes.
  • a ship does not have a homogeneous surface temperature, but rather large areas with significant temperature differences.
  • the temperature zones most frequently recognizable on the thermal image in a ship are the solar-heated hull (approximately 40 to 60 ° C) and the hot chimney (s) (approx. 100 ° C), which form so-called "hot spots", whereby the chimneys stand out much more strongly due to their higher temperature (corresponding to the radiance).
  • two types of active masses can be fired which have different spectral properties.
  • the decomposition size of the active mass with a diameter of 10 m and more (depending on the decomposition load and the quantity of the active mass) produces the three-dimensional one Apparent target body and can be adapted to the object to be protected.
  • An ammunition 2 (active mass 2) is used for the spatial and spectral replication of the hot spots (chimneys), the characteristics of which are explained below with reference to FIG. 7.
  • the active mass of the ammunition 2 is intended to produce approximately the same spectral radiance.
  • the spatial extent is generated by the decomposition size of the active mass ( ⁇ 10 m or more, depending on the decomposition charge and the amount of active mass) and can be adapted to the dimensions of the object.
  • the types of ammunition are taped (ie all on one ammunition belt) and fired from a single launcher.
  • one launcher preferably deploys only one type of ammunition.
  • the control of the output is carried out in the most favorable case by a computer system in connection with the digital evaluation of an own thermal imaging device.
  • the computer control generates the dummy target pattern in accordance with the object shape and its IR signature.
  • the computer independently checks the fidelity to the original and compensates for imperfections in the pattern (due to wind drift or extinction of the active masses) by deliberately constantly reworking the apparent target.
  • Barr & Stroud IR 18 52 pixels, range 8 ... 13 ⁇ m
  • the computer can determine from the image coordinates together with the associated image indices both the firing coordinates and the type of ammunition for them next firing sequences in order to optimally match the (stored) IR ship pattern in Achieve shape and spectral signature.
  • the computer control sets the dummy target (in the best case) between the object and the IR target seeker at a distance of approx. 50 m to 100 m from the object.
  • the successive separation of the re-sewing and the maneuvers of the ship result in a progressive separation of the apparent target and the ship.
  • the IR beam seeker is "pulled away" from the ship by the increased beam strength of the dummy target compared to the ship.
