  • An object protection system is also the subject of DE 10 2004 005 105 A1 , A light ammunition magazine is with the DE 10 2006 004 954 A1 published while the DE 10 2005 054 275 A1 another self-protection system shows.

  • EP 0 588 015 B is also a one-sided transparent infrared nebulas known, which is formed by a curtain of infrared emitting particles, the own thermal imaging device is not or only slightly disturbed while maintaining a sufficient camouflage effect. This is achieved by a special composition of the particles. In order to minimize the influence of this wall on the own thermal imaging device, the device optics are strongly dimmed, whereby a large depth of focus is achieved.
  • a method for generating a one-sided in the infrared spectral transparent camouflage gives the DE 199 14 033 A1 at.
  • a known pyrotechnic Tarnnebel is spread with pyrotechnic scattering particles and irradiated this two-component mist from the side of the applicator with an IR radiation source.

  • the control of the output is carried out by a computer system in conjunction with the digital evaluation of a thermal imager.
  • the computer independently checks the original fidelity and compensates for defects in the pattern (by wind drift or extinguishment of the active masses) by purposeful continuous approaching of the decoy target.
  • the thermal image is monitored pixel by pixel over the entire thermal image, with each pixel acting as a quasi-point radiometer.
  • the associated pixel index (brightness value), which is proportional to the radiation density, is obtained for each pixel. From the image coordinates, the computer can determine the firing coordinates as well as the type of ammunition for the next firing sequence.
  • Imaging agents disclosed therein may be, for example, explosive substance, flammable substance, incandescent or luminescent material, or other materials that provide a good visible temporary image, radar image, and / or a thermal imitation of a target.
  • the firing of the projectiles may preferably be controlled by a microprocessor to allow accurate firing of the projectiles at the selected speed.
  • the object of the invention is to provide a device and an optimized method for producing a one-sided transparent mist, whereby an optimal privacy of an object is realized.
  • the effectiveness of a fog system or fog cloud is dependent on the environmental parameters on site, such as wind speed. Wind direction and relative humidity, etc. Such parameters are disregarded due to the non-predeterminable values.
  • the fog is often driven by the action of the wind not only from the line of sight, but also the fog cloud accordingly defibrated, so that gaps. Also, the proper motion and the spontaneous use of the fog system in 360 ° are not considered. Similar influences arise in calm weather, however, driving the vehicle. Again, it may happen that the line of sight is briefly interrupted by the fog.
  • the effectiveness of, for example, an infrared nebula is dependent on the density of the infrared emitting particles. Due to environmental and systemic effects temporal and spatial inhomogeneities of the wall arise, which leads to a restriction or to a loss of effectiveness.
  • the invention is therefore based on the idea to create multi-spectral fog walls, in which the threat direction, threat distance, wind direction, wind speed, direction of travel and speed in the temporal and spatial application of the visual and infrared line-of-sight are taken into account.
  • the charm of the idea lies in the fact that these information / parameters are not measured separately or even need to be known. Rather, quality and quantity, that is, the density and homogeneity of the cloud of fog (s) are determined.
  • friend-side transparent smoke walls can be generated that do not disturb a private thermal imaging device while maintaining a sufficient camouflage effect. This ensures that the platform, such as a vehicle, by the homogeneously distributed infrared radiating particles and a one-sided transparent infrared effectiveness is created, but these are protected against wind attack and vehicle independent of an enemy attack.
  • the measurement of the cloud of fog for density and homogeneity and thus the effectiveness of the fog wall in the vicinity of the line of sight is accomplished in the visible range, for example by a TV camera.

  • a wind sensor can be integrated, its information for better alignment of the projector and thus the formation of the smoke screen can be used. This creates a good smoke screen for the viewing area as well as a sufficient infrared effect in the fog wall.
  • the method for generating a line of sight interruption is now independent of wind and travel. It is created in the visible wavelength range opaque in the infrared areas but a residual transmission fog cloud. This is achieved (manipulated) by a clever choice or selection and coordination of the fog substance itself, the fog concentration and the thickness of the fog wall, as well as the infrared particles during fog burn. Disturbance variables are largely eliminated by the digital image processing of a thermal image and the thermal image is thus "friend-friendly" optimized.

Although this is significantly disturbed by the infrared particles ( Fig. 6a ), but can be improved by means of complex image-optimizing methods and algorithms.
