Abstract

It is proposed that the functions of camouflage and jamming be absolutely separated. This allows the use of a small-caliber munition (4) which exclusively deploys jammers (6). These jammers (6) or munitions (4) are preferably fired vertically upwards or laterally from the vehicle (object 9) to be protected. For this purpose, the launch barrels (2) are fitted and aligned vertically on the vehicle or the object (9) to be protected. An adequate light flash (8) is produced in the relevant. spectrum by initiation of a pyrotechnic charge, with the initiation being clocked in time and being arranged offset in height, and with the light flash (8) interfering with the aiming mechanism of the approaching warhead. Alternatively, different heights of the break-up flashes can be generated above and/or to the side of the object (9) by a plurality of munitions (4).

Description

Rheinmetall Waffe Munitioli, II euenburg W.BU.0322.WO/DIE June 13, 2008 DESCRIPTION
Method and launching apparatus for protection of an object against a threat, in particular a missile, as well as munition So-called jamming (interference sources) is used, for example, to divert anti-tank guided missiles by means of deployed jammers. Signatures are produced which correspond to the motor of the enemy rockets. The motor is continuously measured in order to control the rockets from the launching apparatus, and the deviation from the expected flight path is carried out by correction of the rockets. This guidance mechanism is influenced by the additional signatures. The rockets are deflected from the flight path.

Jamming can be carried out optically or pyrotechnically. One optical variant is the generation of light flashes by means of a stroboscopic lamp which is fitted in a stationary position on the vehicle. One pyrotechnic variant is pyrotechnic burning in the relevant spectral band by means of a pyrotechnic flare, similar to a Bengal flare.

When pyrotechnic solutions are present in the munitiorl, the jamming is produced by the same munition that is also used to produce the visual blockade (smoke). Light flashes are generated by means of an appropriate break-up charge, integrated in the smoke muriition (DE 38 35 887 C2; DE 28 42 797 C2; DE 10 2005 020 159 A1).

DE 10 2005 054 275 Al describes a self-defence installation for combat vehicles or other objects to be protected. The launch system of the self-defence insta1lation is in this case fitted primarily with a W.BU.0322.WO/DIE - -pyrotechnic munition, in which irritation bodies are included which, immediately after release, produce a powerful light flash and/or smoke. A smoke munition is added to the irritation bodies, for this purpose.

J
EP 0 512 202 A2 discloses a method for protection of objects which emit IR radiation, in which, after the missile has been located, a large-area pyrotechnic jamming radiation cloud is produced between the missile and the objet, which cloud first of all briefly emits powerful infrared radiation, which itself interferes with the lock-on and tracking electronics of the homing head. This jamming radiation cloud then emits weak infrared radiation for a comparatively long time. Only after this are a plurality of spoof target clouds created, which deflect the missile step-by-step away from the object to be protected.

The disadvantages of the optical solutions are the high level of technical complexity, the heavy weight and the long firing chain before they become effective.

In the case of pyrotechnic solutions, it has been found that, because of the relatively large munition caliber, it is possible to store and to carry in the vehicle only ammunition for a few missions. Furthermore, the munition is heavy. Furthermore, the ammunition consumption is high because of the normal false-alarm rate.
Conventionally, the munition is fired in the threat direction. This generally depends on alignment of the munition launching installation (DE 10 2005 020 177 A1), which can result in a time delay. A plurality of installatiorls are often necessary in order to allow all threat directions to be covered at the same time (DE 10 2005 054 275 Al).

Vu . i~u . 0~__~ . WG / DT F - ~

Known munition launch installations frequently require a large amount of space and are often difficult to integrate, in particular in vehicles.

A further disadvantage is the muni_tiori itself. 'The functions of jamming and camouflage, for example by means of smoke, are in gerieral always deployed together by this munition. However, smoke iri particular is riot always desirable since it carl impede one's own view.
The invention is based on the object of improved jamming associated with an improved integration capability, by saving weight in the launch installation.
The object is achieved by the features of patent claim 1, patent claim 4 and patent claim 6.
Advantageous embodiments are specified in the dependent claims.
The invention is based on the idea of absolute separation of the functions of camouflage and jamming.
This makes it possible to use a small-caliber munition which deploys exclusively jammers. These jammers or munitions are preferably fired vertically in height and/or laterally by the vehicle (object) to be protected. For this purpose, the launch barrels are fitted and aligned vertically on the vehicle or the object to be protected. Arl adequate light flash is produced in the relevant spectrum by initiation of a pyrotechnic charge, which irlitiat.ion is clocked in time and is arranged offset in height, and the light flash irlterferes with the aiming mechanism of the approaching warhead. Alternatively, different heights of the break-up flashes above and/or to the side of the object can be generated by a plurality of munitions.

W.BU.0322.W0/DIE - 4 -This measure for deployment of the jammers is deployed separately from other effects, such as smoke. The smoke munition, which can be fired separately, then does riot itself need to carry out jamming. This allows a plurality of smoke bodies to be included in the actual smoke munition.

Launching is carried out electrically or mechanically, initiated by a small, compact launching apparatus, for example from magazines. The sub-clocking for initiation of the individual light flashes is controlled by electronics. These electronics are preferably a component of the launching apparatus.

The advantages which result from this are a small launch design, with no aiming elements being required, and lower weight associated with this. Because of the lack of aiming elements, simple integration and a simple technical implementation are possible.
The invention will be explained in more detail using one exemplary embodiment and with reference to the drawing, iri which:

Figure 1 shows a launcher with a munition, Figure 2 shows the munition from Figure 1, and Figure 3 shows an integration optiori on/to a vehicle.
Figure 1 shows a compact launching apparatus or a launcher 1_ in a transparent form, preferably with a plurality of launch barrels 2 which are aligned upward parallel and form a magazine 3. One munition 4 is located in each of these launch barrels 2.

Figure 2 shows the design of the munitions 4. The munition 4 comprises a casing 5 from which one or more W.BU.0322.W0/DIE - 5 -sub-munitioris 6(jammers) are fired. Alternatively, the sub-munitions 6 (jammers) can be fired directly from the magazine 3, without a casing. The munition 4 or sub-munitions 6 has/have a comparatively small caliber for vehicle protectiorl muriitions, for example 40 mm (medium caliber).

The munitions 4 or the sub-munitions 6 have interfaces to the launching apparatus 1, via which they are 10 initiated electrically or mechanically. The sub-clocking for initiatiori of the individual light flashes 8 is controlled by electronics 7. These electronics are preferably a component of the launching apparatus 1. In order to initiate the light flash or break-up flash 8, a plurality of sub-munitions 6 and/or a plurality of munitions 4 can be initiated, clocked in time, successively.

The break-up flashes 8 of the jammers 6 are generated spatially above the vehicle 9 (Figure 3) . The break-up height is preferably in the range from about 3 to 15 m above the vehicle 9. In this case, the height rises within the individual light flashes 8. Firing is preferably carried out from the vehicle 9 vertically upward. A lateral break-up can thus be set, with the break-up taking place with decreasing height.

Figure 3 shows an example of an arrangement of a launching apparatus 1 on a vehicle 9. The break-up flashes 8 are generated at heights of, for example, 4 m, 8 m, or 12 rn above the vehicle 9.
