Definitions

  • the invention relates to a device for false target generation and camouflage, in particular on ships, to complicate or prevent position determination in the case of external location by means of radar and / or heat measurement, such as. B. infrared measurement.
  • dummy target material e.g. B. to shoot from a ship to complicate the foreign location.
  • the dummy target material consists either of metallic materials (dowels), which cause reflection of the electromagnetic radiation in the radar range, or of so-called infrared flares with heat-emitting substances, which can be measured using heat measuring devices, e.g. B. IR locators are perceptible.
  • This known deception system is only suitable for creating a false target, but cannot be used for the radar and IR camouflage of the ship itself.
  • the disadvantage is that camouflage of such a ship is not achieved despite IR-shielded exhaust gases and that the ship can be located perfectly and with sharp contours by radar.
  • Another method described in DE-A 3 217 336 is intended to produce a closed water curtain in the form of a coherent film which can be located.
  • the contours of a ship can become invisible with such a water curtain, but the reflection of the order rays on the water curtain is registered almost as much as on the object itself. Radar measurements of the ship to be camouflaged are no longer possible with a water curtain. So the ship goes blind. However, if the radar mast protrudes beyond the water curtain, it is sufficient as a marker for the target.
  • a water curtain requires a very large amount of water. It is practically impossible to completely encase a ship, for example to protect it from localization. Operation over a longer period is not intended.
  • the object of the invention is to remedy the disadvantages described above in known devices and to provide a device which is relatively simple and works only with a means which is available at any time in unlimited quantities and is environmentally friendly. The use of expensive, different and environmentally harmful means should be avoided. Furthermore, the further task is to create a uniform device with only one means, with which both electromagnetically acting and heat-emitting false targets can be generated, and, if necessary, IR shielding can also be achieved without an additional device.
  • a ship equipped according to the invention is able, for. B. with ESM alarm almost free of distortion with the liquid mist-producing throwers to generate finely nebulized water clouds with small and tiny drops in such a density that appear as separate targets in radar location, which makes target acquisition of the real target difficult.
  • a continuous water mist generation due to the inexhaustible amount of the apparent mock target, namely water, with a corresponding performance of the thrower a large-area water mist cloud can be achieved, which is larger than the ship to be located, so that the deception and camouflage by blurring the contours even more effectively is.
  • the present invention exploits the knowledge of radar application in meteorology. For example, from the book “Radar and radio navigation", 1973 edition, Vogel-Verlag, Würzburg, para. 1.9.3. known that radar measurements at greater distances are affected by cloud absorption and scattering and raindrops, and that clouds are detected at distances of several hundred kilometers, especially when they start to rain. It has also been found that tracking radars are used more successfully to determine air movements.
  • the invention is based on the idea of producing artificial water mist clouds in order to use them for camouflaging ships.
  • a variety of surprising, unforeseen effects were shown, u. a. that in the production of water mist clouds of fine and very fine drops and a variable density by pressure control at the atomizing nozzles a more or less desired reflection of the radar waves of different frequencies can be achieved.
  • water fog clouds of high density - comparable to heavy rain - z. B. achieved a desired strong reflection, which in turn scattered reflections z by the spherical shape of the precipitation particles. B. cause waves and when returning to the antenna can lead to the desired measurement distortion at the opponent.
  • the dummy target display for IR location using warm water possibly with the addition of an environmentally friendly alkali metal, e.g. B. sodium, for increasing the temperature in the water mist cloud can be carried out simply and effectively.
  • an environmentally friendly alkali metal e.g. B. sodium
  • a ship 1 is shown from the front view, on which - shown schematically - a launcher 2 can be seen on the starboard side.
  • the ejection axis 3 is raised from the horizontal 4 by the angle alpha, the thrower reaching the maximum throw distance at an angle of approximately 45 ° , taking into account the wind direction 5 and speed, and producing a water mist cloud 6 far from the ship 1.
  • a relatively elongated water mist cloud 6 is generated as an apparent target, which apparently moves with the wind as a large target in direction 7 across the course of the ship 1.
  • further water mist clouds 8 can be generated, whereby the impression that several objects are moving in the direction 7 can be obtained upon location.
  • target detection e.g. B. narrow, up to wide, elongated water mist clouds.
  • target detection e.g. B. narrow, up to wide, elongated water mist clouds.
  • a reservoir e.g. B. heated in a pressure tank, not shown, below deck, from which the pumps of the thrower are fed.
  • heat generating chemicals can be added to the medium in such a reservoir, e.g. B. an alkali metal such as sodium or electromagnetic reflecting additives, for. B. a suitable metal powder.
  • a launcher 9 is shown on the port side and is directed upwards from the horizontal 4 at an angle 10. This representation is intended to show how. B. an IR shield, e.g. B. the exhaust gases 11 can be made.
  • the medium producing liquid mist is first expelled on the windward side in approximately vertical direction 12 by the launcher 9.
  • the discharge angle 10 and the discharge pressure are adapted to the wind speed from the direction 5 in such a way that a mist vane 13 wraps around the upper region of the chimney 14 and envelops and cools the exhaust gases 11 escaping from it.
  • the fog flag 13 can be controlled such that, for. B. if necessary, the antennas, for. B the radar antenna 15 protrude from the fog flag 13 and the damping influence on the emitted radar radiation is reduced to a minimum.
  • water mist clouds 16 can be generated against the wind direction 5 by further launchers arranged on the port side, in order to possibly cover further heat-radiating surfaces of the ship on the port side.
  • additional launchers 17 and 18 are expediently arranged on the bow and stern of the ship, so that a contour-blurring apparent target display or IR shielding can be achieved in the event of external location.
  • the turrets arranged around the ship can also consist of turret tubes that can be controlled in terms of direction, height and pressure, which can be fed from a common pressure reservoir, whereby any selection and number of turret tubes can be activated, depending on the tactical requirements.
  • the function of the thrower can either manually or automatically by an electronic control such. B. switchable ESM alarm.
  • the water mist clouds remain for a certain time.
  • suitable, possibly also adjustable nozzles of the water cannons the density of the cloud and the floating time of the droplets or particles can be influenced, taking into account the weather conditions.
  • the device is also advantageous for camouflage purposes or target deception on fixed objects, e.g. B. bridges, floating bridges, ammunition depots and fuel stores, but also on endangered land vehicles, e.g. B. tanks, ammunition and tank vehicles can be used.
  • fixed objects e.g. B. bridges, floating bridges, ammunition depots and fuel stores
  • endangered land vehicles e.g. B. tanks, ammunition and tank vehicles
