Definitions
- the invention relates to adaptive camouflage for targets such as vehicles, ships or aircraft, by emitting light from external light sources onto the visible surface of the target.
- Suitable camouflage is used for camouflage compared to electro-optical sensors
- Location target applied in the surface areas visible by external sensors.
- the Illumination is usually set so that the radiance is that of the observed Optical radiation emanating from the target is as good as possible from that emanating from the target background Radiation corresponds.
- DE 34 01 919 A1 describes a camouflage projector which is controlled by a camera becomes.
- the camera films the background area hidden from the viewer's perspective, which is projected onto the surface of the target at the same time and in terms of size.
- the background information be displayed using internal projectors project the semi-transparent target surface.
- projectors can be fast, also spatially and temporally varying Setting the radiance from the target can be achieved.
- the target surface must remain semi-transparent.
- a tolerability measures for radar camouflage are only partially available with internal projectors, because semi-transparent radar absorbers would be required in the visible spectral range. About that In addition, this document does not take into account the military spectral ranges IR and UV.
- FIG. 1 shows part of the target surface 1 of an unspecified target.
- Light sources 2 arranged. The arrangement is preferably such that the light source 2 from the Area in which an observation with external sensors 3 is expected cannot be viewed directly is. These light sources emit light in a short-wave spectral range than the sensor 3 can register. The light from the light sources 2 strikes that observed by the sensor 3 Target surface 1.
- This target surface is provided with a fluorescent coating 4, which converts the striking light into a long-wave light that can be detected by sensor 3. Fluorescent coatings usually interfere with the camouflage measures that are also necessary against radar radiation, since they are usually neither electrically conductive nor are designed to absorb microwaves.
- the primarily expected Observation direction of the sensors on the target are taken into account. For example Illumination of the top of an aircraft by assumed observation Soil sensors not necessary. If parts of the visible from the expected sensor 3 Target surface 1 can only be poorly illuminated, so the corresponding Area size in relation to the entire target surface. If they don't illuminable area small compared to the entire target surface or the resolution of the Sensor 3 is, under certain circumstances, no further efforts to illuminate become.
- IR camouflage in the IR range Embodiments are well known. For use in the IR range, that of the Radiation and thermal insulation initially emitted the target surface below the lowest expected background radiance can be brought. Then through Illumination with appropriate IR light sources the target surface 1 in all situations IR background can be adjusted. This type of IR camouflage takes advantage of the Temperature control for greater flexibility and rapid variation in radiance. When using remote light sources, it is still in the case of a dirty target surface effective.
- the coating 5 is light-guiding. Feeding the to emitting light occurs indirectly either by coupling from the inside through the External structure 1 of the target or by means of lateral coupling of the light from the light source 2 as it is shown in Figure 2.
- the decoupling of what is required to deceive the sensor 3 Light occurs either at discrete locations 6 or distributed over the outside of the area Surface layer 5.
- Large-area light-emitting diodes can be used as light sources, for example serve photoelectric polymers. Materials such as are suitable for the surface layer Electroluminescent films or in a special way mats made of optical fibers. Draw the latter are characterized by their compatibility with radar camouflage measures.
- the illumination of the target surface can also be generated by controllable shutters Patterns that can also be varied spatially and temporally together with the brightness control can be used. In this way, background patterns can be imitated in order to Sensor 3 to complicate the location of the target.
- Deceptive evaluation algorithms from sensors. For example, a rocket reaches a large one Proximity to the detected target limits the field of view of the missile's IR seeker head exclusively on the target surface. In this situation, one can be significant for the sensor 3 Luminous spot are generated, which in the final phase of the approach over the target surface is led that the missile - he following - is guided past the target. A suitable one Guiding the significant light spot is a strongly accelerated movement across Approach direction of the missile to the edge of that seen from the missile sensor 3 Target projection.
