Definitions

  • the invention relates to a method and a system for determining and displaying a Shot error according to the preambles of independent claims 1 and 2 respectively.
  • Procedures and systems of this type are used in practice shooting. While it in the event of war when a enemy aircraft is shot at, generally for the gun crew is not difficult, possible hits and therefore success or to determine failure of the fire, this is during target practice, where preferred shooting at non-flammable and non-crashing destinations is more difficult.
  • Various methods have long been used to avoid such difficulties and shot detection equipment used in the attempted Hit a flight target by projectiles fired from ground / air guns.
  • shot error refers to the minimum distance understood between the destination and a projectile.
  • this minimum distance is conventionally carried out as follows: by means of a Image acquisition devices are arranged at a mutual distance from two Score a sequence of pictures or a film of the flight destination and one in the area of the aircraft located projectiles and at the same time found under what angles, based on a reference position, the pictures are taken. These films are then manually processed in an image processing device or semi-automatically two different time-level flight curves of the flight destination and determined two different temporal plane flight curves of the projectile.
  • the two temporal plane flight curves of the flight destination the temporal spatial trajectory of the flight destination and from the two temporal plane flight curves of the projectile spatial trajectory of the projectile calculated; in the temporal spatial trajectories in the mathematical sense, there are four-dimensional curves, since each curve point three length dimensions and one time dimension must be attributed.
  • the two spatial trajectories of the flight target and the projectile are compared and the minimum distance between them is determined, the minimum distance between the flight target and the projectile and thus corresponds to the shot error; this minimum distance is generally not the same as the minimum distance of the trajectories the destination and the projectile.
  • the shot error so determined becomes the Gun crew displayed.
  • projectiles are generally not considered Single storeys but delivered in series fire; instead of individual trajectories Projectiles are then to determine trajectories of projectile sheaves.
  • Bullets are often collapsible bullets, mostly also Disassembly time can be determined.
  • Particular problems arise when multiple destinations are available, which would be necessary to create a realistic scenario.
  • the prevailing meteorological conditions also play a certain role.
  • the target practice can not only be qualified as a 'hit' or 'miss', but that by knowing the movements of the projectiles due to the movement of the destination takes place, a detailed analysis of the shooting errors and a thorough assessment of the gun crews to be trained is possible.
  • the disadvantage of the known method or the known system is to be seen in that the time required by the image processing device and the computer unit around the temporal spatial trajectories of the flight destination and the temporal spatial Delivering trajectories of projectiles is very large.
  • the gun crews Therefore, the gunshot errors only occur after the actual has been completed Shooting exercise brought to the attention in the course of a later exercise critique.
  • a large number of flight passages take place and always do so one or more sheaves are fired are in the subsequent exercise review, where the gunfire, its causes and consequences to the gun crew be announced, the circumstances of the individual passages and gunshots often no longer present.
  • the learning effect for the gun crews is therefore limited, although the teaching staff can assess the progress made is possible.
  • EP-B1-0 018 673 discloses a hit measurement used for the formation of anti-aircraft troops, in which the shot errors can be transmitted to the gun operating teams somewhat more quickly, namely within a few minutes, and can be displayed on a screen.
  • this system has several disadvantages. For example, the time it takes for gunshot reports to be reported to the gun crews is still relatively long. It is more serious, however, that the method used to determine the trajectory requires a distance measurement using a laser device, and that the objects to be detected, i.e.
  • the flight target and the projectiles must in principle be in the middle of the recorded area and cannot leave it, since otherwise it is no longer possible to assign the depicted points to the individual shots of a sheaf; Furthermore, the system is not suitable for the mirror shooting explained below, which is often carried out and is practically indispensable in shooting training.
  • the object of the invention is thus seen in a method and a system create a reliable determination while avoiding the disadvantages mentioned and allow rapid display or feedback of the shot errors, so that the Shooting training of the gun crews in a realistic Can play the scenario efficiently and with an economical and ecological reasonable effort is feasible.
  • the image processing for the flight destination and the projectile take place in real time as well as the triangulative calculation of a chronological sequence of points of the flight destination, the sequence from which a temporal spatial trajectory of the destination is calculated; in quasi real time find the calculation of two temporal plane flight curves of the projectile and the triangulatory calculation of a temporal spatial trajectory of the projectile from its two temporal plane flight curves instead; also takes place in quasi real time the comparison of the temporal spatial trajectories of the flight destination and the projectile or the determination of the shot error and its display instead.
  • the advances achieved by the invention are the result of the combination of the in its basic features of the previously known method for determining the shot error on the one hand with the real-time or quasi-real-time calculation processes and the online display of the shot error in quasi real time.
  • the method according to the invention and the system according to the invention can be started adapt various weapon systems and ammunition types.
  • the detection and tracking of the flight destination and the triggering of the shot take place visually-manually on the gun itself.
  • the weapon system in this case includes guns and fire control devices, a fire control device generally interacts with one to three guns.
  • the gun operating team is responsible, apart from in Position the gun and from the ammunition supply to the gun, only control of the course of judging and firing, while the rest Transfer tasks from the gun operating team to the fire control unit, whereby within the scope of the present description the fire control unit crew as to the gun operating team is properly considered.
  • a fire control device recommendable for successful tracking and Bombardment of fast flight targets such as fighter jets is a fire control device recommendable.
  • Each image acquisition unit in the new system has a sensor part that detects the object to be captured externally, follows it and displays it at short intervals. Furthermore, the image acquisition unit has a position measuring device, with which the respectively associated spatial positions of the images are determined on the basis of measurements of angle pairs carried out relative to a reference line, specifically in synchronism with the respective recording of the objects.
  • the sensor part has a camera as a sensor. If as ammunition to be fired Tracer ammunition is selected, and if visibility is always acceptable, so a video camera is used. To fire other types of ammunition and / or to perform shooting exercises in exceptional visibility conditions, For example, a FLIR camera can be used, but this is more expensive than the commonly provided video camera. The new system allows the Carry out sensor changes relatively quickly.
  • the position measuring device is generally designed like a theodolite.
  • A is essential very quiet, low-friction and play-free running or a corresponding storage and a corresponding drive.
  • drones In principle, it would be possible to use drones to be used, which are fired at directly, but drones are used with regard to To approach speed and maneuverability on fighter jets, very complex, so that their use is associated with relatively high costs.
  • the advantage of using of drag bags and drones, if any, is that they form flight destinations, which can be directly detected, tracked and shot at, so that at least in this relationship realistic scenarios can be generated. Target practice, that occur within such scenarios are called direct target shooting.
  • the image capture device required for this comprises two image capture units, which are positioned at a mutual distance. Each image capture unit is for the shot determined by an image sequence of the flight destination and the projectiles and with an image processing unit connected, which temporal level flight curves of both the destination like the projectile delivers.
  • the image capture device must have four image capture units. Two spaced apart image acquisition units are on the airspace area of the real plane that cannot be hit should, directed and deliver two image sequences and associated sequences of pairs of angles which with the aid of two image processing units connected to the image acquisition units and a first computer unit a temporal spatial trajectory of the Aircraft are calculated.
  • two further image acquisition units deliver the on the mirror symmetrical airspace area and thus on the real projectiles are aimed, with the help of two further image processing units and a second computer unit has two temporal, level flight curves or flight curve groups of the projectile or projectiles and from them a temporal spatial trajectory or Trajectory family of the projectile or projectiles.
  • One each on the plane and one Image acquisition unit directed at the projectile (s) are adjacent to one another arranged.
  • An advantage of moving target shooting is that it is easily possible to achieve a realistic one Scenario not only with one but with several at the same time in the target area create fictitious or mirrored flight destinations, which one after the other can be shot at, the guns each so-called target change have to perform.
  • the second computer unit Following the determination of the temporal three-dimensional trajectory of the flight destination and the temporal spatial trajectory of the projectile is determined by the second computer unit by comparing the three-dimensional trajectories of the projectiles and the flight target the minimum distance between the flight target and the projectile, which is within the scope of the present Invention is defined as a shooting error.

  • the feedback or notification of the shot error to the gun operating teams can also be carried out in such a way that only one central display unit is present is, and that the feedback to the gun crews is verbal he follows.
  • Such a type of shot error feedback can and is done quickly significantly easier in terms of the equipment required, but much less effective efficient than the display device described above with multiple display units.
  • the stated aim of the invention is to provide a quasi real-time error display realizing, it is an advantage if the shot errors, together with the data, that define their affiliation, can be archived for later viewing.

It must be ensured that the visual perception is not impaired by rain, snow or fog. In addition, the image acquisition units must be protected from direct sunlight by sun visors. The combination of a sun visor with a sliding protective device has proven to be cheap.

  • Each of the image processing units 20.1 to 20.4 supplies the positions of the object captured by the associated image capture unit relative to a reference point, for example the image center of the corresponding captured image.
  • the flight destinations 10 are generally not taken under single fire but under series fire. Instead of the flight curve of a projectile, a flight curve family of a bullet sheaf must then be recorded and processed.
