Definitions

  • This invention relates to training apparatus, and is more particularly but not exclusively concerned with training apparatus for training tank and/or gun crews in the use of thermal imaging observation systems and/or thermal imaging aiming systems associated with weapons.
  • one form of training apparatus for training tank and/or gun crews in the use of weapons having thermal imaging aiming systems comprises a dummy target, typically a full size silhouette of a tank, which is positioned at a normal operational range with respect to the weapon and sight.
  • This target is provided with local heating devices adjacent the parts thereof which would be likely to be hot if the target were real, eg in the case of a tank, the breech-end of the barrel of the main gun and the engine compartment, so that when the heating devices are energised, these parts will show up in the thermal imaging sight.
  • training apparatus for training weapon crews in the use of thermal imaging observation systems and weapons having thermal imaging aiming systems against real targets having predetermined regions of likely elevated temperature, the apparatus comprising:
  • apparatus for simulating a real thermal target comprising a dummy target, at least one infra-red reflector means secured to the dummy target, and source means, remote from the dummy target, for producing a beam of infra-red radiation which is directed at and illuminates the dummy target.
  • real target means any target at which a weapon would be fired in a real combat situation
  • dummy target means a target which is used for training purposes and which merely represents such a real target, however inaccurately or incompletely.
  • the dummy target comprises a frame covered with cloth or other suitable material and shaped to represent a silhouette of the real target
  • the reflector means preferably comprises one or more patches made from or coated with an infra-red reflecting material and stuck or otherwise secured to the dummy target.
  • the reflector means is retroreflective, that is, it reflects incident light mostly straight back along the line of incidence.
  • the source means comprises an infra-red laser.
  • a low-power carbon dioxide laser advantageously a low-power carbon dioxide laser
  • Figure 1 shows two tanks 10 whose crews are to be trained in the use of thermal imaging aiming systems (not shown) associated with the main guns 12 of the tanks.
  • the tanks 10 are positioned at a firing point 14 on a firing range 16, and are firing at a dummy target 18 in the form of a silhouette of a tank.
  • the target 18 is positioned within the operational range of the guns 12 and their sights, typically at say 1000 metres or 2000 metres from the firing point 14.
  • the dummy target 18 is shown on an enlarged scale in Figure 2, and comprises a wooden or aluminium frame 20 covered with cloth or other suitable material 22. Secured to the portions of the target 18 approximately corresponding to the respective positions of the breech-end of the barrel of the gun and the engine compartment of the tank represented by the target are respective infra-red retroreflective patches 24. These patches 24 may each comprise, for example, a polymeric film moulded, pressed or rolled to form in its surface a multiplicity of small depressions covering the entire surface. Each depression has three mutually perpendicular intersecting walls, such that it effectively constitutes a retroreflector of the corner-cube type. The surface of the film, and thus the surfaces of the walls of each small depression. is then coated with indium oxide or tin-oxide, to enhance its infra-red reflecting capability.
  • infra-red laser projector 26 mounted on a tripod 28.
  • the projector 26 which comprises a relatively low-power (and therefore eye-safe) carbon dioxide laser, produces a beam of infra-red radiation which is directed towards and illuminates the target 18 throughout the duration of each training session. The beam is reflected back along its line of incidence towards the tanks 10, thus enabling the target to be seen, and therefore aimed and fired at, using the aforementioned thermal imaging aiming system associated with each gun 12.
  • the target 18 is relatively inexpensive, which is a considerable advantage in view of its expendable nature. Also, it is light in weight. and therefore relatively easy to transport, and relatively quick and easy to set up. Further, the laser projector 26 is located at and controllable from the firing point 14, which is extremely convenient.
  • the retroreflective patches 24 can be made from aluminium foil stuck to a substrate of polythene or other infra-red transparent material, or sandwiched between two such substrates, and then moulded, pressed or rolled to form retroreflectors in its surface, as described above in relation to the polymeric film patches 24.
  • the intensity of the radiation reflected from different parts of the target 18 can be varied by extending the coverage of the patches 24 and then applying an absorbing coating of paint or some other partially transmitting covering over selected parts of the patches, so as to simulate accurately the different levels of infra-red emission typically produced by real targets.
  • the patches 24 can be simply reflective rather than retroreflective, but that requires the use of a more powerful laser in the projector 26 and/or reduces the range over which the apparatus can be used.
  • the laser projector 26 is more closely associated with the weapon with which it is being used as a training aid, for example by mounting it on or in the turret of the tank 10, in close proximity with the thermal imaging aiming system.
  • the projector 26 can even form part of a more comprehensive training system, such as that manufactured by the Applicant under the trade mark SIMFIRE, mounted on each tank 10.
  • the training apparatus of the invention can be used with weapons other than tank guns, for example with artillery and infra-red homing missiles.
