Definitions

  • the invention relates to a device for protecting mobile objects, especially armored vehicles against projectile impact, in particular the impact of Missiles and / or high-speed projectiles, the genus defined in the preamble of claim 1.
  • the locating device comprises e.g. one or more Transmitter and a plurality of receivers, each assigned a group of shaped charges to a receiver which are ignited simultaneously as soon as in its Reception sector a floor is located.
  • Such locating devices have the disadvantage that the constant emission of electromagnetic waves mobile object much easier and over a very much greater distance can already be made out, even then when it is not yet graspable by visual means is. With active self-protection, a considerable amount is possible Probability of treason. This could be because of this be circumvented that the self-protection device only then is activated when immediate combat operations are imminent, so that the mobile object is already from opposing forces, but that's it mobile object on the rise or advance completely defenseless against surprise attacks.
  • the invention has for its object a Protective device of the type mentioned above improve that they make no contribution to a facilitated Detection of the mobile object delivers a reliable Ensures self-protection and at low production costs is available.
  • the task is at a facility to protect mobile objects in the preamble of claim 1 Specified genus according to the invention by the features in Characteristic part of claim 1 solved.
  • the protective device according to the invention has the advantage to locate only with passive means, which by opposing forces can not be identified.
  • a approaching projectile becomes after perception or detection very quickly with regard to its position, direction of flight and Airspeed measured so that the projectile in sufficient distance in front of the object not only with Cluster munition but also harmless with a guided missile can be made.
  • the cost of the Protective devices are also kept low by the fact that when using the invention in tanks Image cameras also as an indirect visual aid for the Tank crew (driver, gunner, commander) serve, the direct one for future generation tanks View will be replaced by a view mirror, and therefore do not have to be procured additionally.
  • uncooled thermal imagers as Image cameras are not just reliable detection approaching projectiles even at night and bright Sunlight or in front of little contrast with the floor Background, but is also ensured by the relatively low procurement cost of such uncooled Thermal imaging devices an attractive price for that Protective device achieved.
  • FIG. 1 shows a main battle tank 10 in plan view, who during his deployment of a threat from a Anti-tank guided missile 11 is exposed.
  • the tank is against destruction by this guided missile 11 10 provided with a protective device with their essential components attached to the outside of the main battle tank 10 is what when retrofitting tanks 10 with such a protective device constructive changes to the tank 10 itself does not occur or only to a small extent.
  • the Protective devices also offer protection against others armor-piercing projectiles.
  • An essential part of the protective device is a device for locating approaching projectiles 11, which has a plurality of sensors designed as image cameras 12, which are distributed over the main battle tank 10 in such a way that a closed monitoring screen is stretched around the tank 10 at a distance from the tank 10.
  • three image cameras 12 are arranged on each long side of the tank 10 and two image cameras 12 are arranged on the front and rear side of the main battle tank 10.
  • the viewing angles of the image cameras 12, which are denoted by ⁇ in FIG. 1, and the distance of the image cameras 12 from one another, which is denoted by a in FIG. 1, are coordinated with one another such that the viewing angles ⁇ 1 ⁇ 2 of adjacent image cameras 121 , 122 overlap.
  • the overlap area is set so that it lies outside a minimum distance in front of the main battle tank 10, which is necessary for the successful projectile control.
  • Uncooled thermal imaging devices are preferably used as image cameras 12, with which approaching projectiles can be recognized very well, since these differ from the rest of the background in a high contrast because of their great heat.
  • these uncooled thermal imagers have the advantage of being available on the market at very reasonable prices.
  • these uncooled thermal imaging devices are also used as indirect sighting means for the tank crew (driver, gunner, commander) for driving and for near-field reconnaissance, so that due to the dual function of the thermal imaging devices, the production costs for the protective device are lower.
  • the image cameras 12 are assigned an image processing unit which continuously determines the projectile position from the coordinates of the projectile image in the two image planes of adjacent image cameras 121, 122 and the mutual distance a between the image cameras 12 and calculates the projectile speed from the changes in position and the scanning frequency of the image cameras.
  • an image processing unit which continuously determines the projectile position from the coordinates of the projectile image in the two image planes of adjacent image cameras 121, 122 and the mutual distance a between the image cameras 12 and calculates the projectile speed from the changes in position and the scanning frequency of the image cameras.
  • the optical axes are denoted by 131, 132, the image planes by 141, 142, the lens planes by 151, 52 and the focal points of the two image cameras 121, 122 by 161, 162, b 1 and b 2 being the image range of each image camera 121 , 122, 11 is the guided missile and 11 'is the image of the guided missile 11 in the image planes 141, 142 of the image cameras 121, 122.
  • x 1 and x 2 are the respective positions of the illustration 11' of the guided missile 11 on the x coordinate of the image plane 141 and 142.
  • the same representation applies to the y coordinate rotated by 90 ° in the image plane 141, 142 of the two image cameras 121, 122.
  • the bearing angle ⁇ 1 and ⁇ 2 can be calculated in azimuth to the guided missile 11, and by means of the known distance a between the optical axes 131, 132 of the image cameras 121, 122, the bearing angles ⁇ 1, ⁇ 2 can be calculated distances r 1 and r 2 projected in the azimuth to the storey 11 calculate based on known trigonometric relationships.
  • the projections of the distances to the guided missile 11 in elevation can be calculated with the same values in the y coordinate of the image plane 141 or 142.
  • the distance from each image camera 121, 122 to the guided missile 11 in space is determined from the two distance components in each case, and thus the position of the guided missile 11 in space.
  • the scanning frequencies of the two image cameras 121, 122 are synchronized with one another, so that the new position of the guided missile 11 can be determined with each exposure of the image cameras 121, 122. Due to the changes in position of the guided missile 11, its trajectory and, with the aid of the scanning frequency of the image cameras 121, 122, its flight speed can be determined with high precision.
  • a device for combating the guided missile 11 activates which control agent emits and which Guided missile, so that this still in sufficient distance from the main battle tank 10 by destruction or distraction is rendered harmless.
  • the control device an example of a number of discharge hoppers 17 for Hollow charges or fragmentation ammunition that are placed over the main battle tank 10 are distributed and each have a specific Cover sector. From the locating device is now the discharge funnel 17 is controlled in the combat sector directed the trajectory of the guided missile 11 is. The guided missile 11 penetrates into an area in which the destructive effect of the discharge funnel 17th the amount of ammunition fired is maximum corresponding discharge funnel 17 ignited.
