Definitions
- the invention relates to a method for providing a target signature of an object, such as a land, air or water vehicle or the like, for an imaging radiation-sensitive target seeker with spectral differentiation, such as an IR seeker, simulating a dummy target body.
- Such a method is known from DE-OS 33 11 530 in which the dummy target body, which is intended to emulate a ship-like target signature, is brought into its position outside the watercraft to be simulated by means of an underwater vehicle.
- the disadvantage here is that the dummy target body as a whole has to be built up by means of a corresponding single active mass, and thus the spatial signature could only be achieved remotely and without temporal stabilization.
- a spatial-spectral distribution of the active mass is excluded.
- IR deceptive 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 target seekers, in particular IR target 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.
- this object is achieved in a further development of the generic method by spatially displacing part of the spatial target signature of the object by emitting radiation in the sensitivity range of the imaging target seeker in such a way into the position of the dummy target body to be generated and disassembling it there that a spectrally differentiated three-dimensional dummy target body simulating the target signature of the object for the target seeker head is generated.
- the active masses are brought into the position of the dummy target body at such a time that the three-dimensional dummy target body is produced essentially continuously for a predeterminable period of time.
- the active masses are positioned under computer control under essentially continuous monitoring of the dummy target body.
- the active masses can be positioned by rapid-fire projectiles.
- the invention also provides that the rapid-fire projectiles are fired from several launchers.
- the invention also proposes that the rapid-fire projectiles be fired with such a cadence that a new active mass comes into disassembly essentially at each predefinable active mass location at the point in time at which the previous active mass expires.
- the invention also provides that different active masses are used for areas of the dummy target body to be set up with different attractiveness for the target seeker head.
- the invention also proposes that infrared active masses are used.
- active substance types are used which each contain phosphor granules and phosphor flares in different ratios, the first active substance type with a higher phosphor granulate component being used to simulate relatively cool and the second type of active material with a lower phosphor granulate component being used to simulate relatively warm object surfaces.
- the invention also provides that the active masses of the first active mass type about 80% phosphor granules and about 20% phosphor flares and the active masses of the second active mass type about 25% phosphor grain contain nulat and about 70% phosphor flares.
- the invention proposes that active materials with a decomposition size of at least 10 m are used.
- the invention is based on the surprising finding that it is possible to specify a method for protection against imaging target seekers that is suitable in principle for all conceivable objects by virtue of the fact that in particular computer-controlled, with essentially continuous monitoring of the three-dimensional dummy target body, active substances, e.g. 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.
- active substances e.g. B. in the form of rapid-fire ammunition relatively small caliber
- 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 dummy 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 beam strengths and / or beam densities etc the overall apparent target is made more attractive to the seeker than the destroyer.
- Figure 3 shows a destroyer with a conventional dummy target (torch) 11 without an object-like contour, so that this is not the real object, that is, by an "intelligent" IR seeker head of the third generation. H. the destroyer 10 will be preferred.
- FIG. 4 showing an ammunition transporter 16 with a single chimney 18. Accordingly, the IR dummy target, shown according to the invention, reproduces a dummy target body 16 'with a single "hot spot" 18' according to FIG. 5.
- the invention has been explained above on the basis of the exemplary embodiments shown for the most common application, the protection of ships, but versions for other objects only exist in ammunition caliber and ammunition composition, which each have to 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
- shape, area size, spatial spectral radiation distribution, movement behavior are reproduced true to the original according to the invention.
- the radiance of the dummy target body relative to the object is increased 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 an apparent target body that is effective for all threats and therefore also for several simultaneous attacks from different directions.
- the method according to the invention enables a three-dimensional dummy target to be achieved by the rapid and continuous targeted firing of specific pyrotechnic active substances realize under the following basic principles: firing order with high cadence, e.g. B. with more than three rounds / 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 cadence of 3 rounds / sec. 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.
- the following time table shows an example of a shot sequence:
- a ship does not have a homogeneous surface temperature, but rather large areas with significant temperature differences.
- 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 charge and the quantity of the active mass) generates the three-dimensional dummy 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 (010m or more, depending on the decomposition load 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) fired from a single launcher, whereby a predetermined order of ammunition must be followed, e.g. B.
- one launcher preferably deploys only one type of ammunition.
- the control of the output is undertaken 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 18 512 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 the next series of shots 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.
