<p>Target apparatus is provided for use in the training of weapon direct fire, including a structure (1) in which a weapon can be placed and which forms a screen (3) of concave truncated spherical shape, at least one target image projector (4) located within the structure (1) for projecting a target image (T) onto the screen (3), with the at least one projector (4) being mounted for universal movement so as to be capable of moving the projected target image (T) over the screen (3), and a visible light projector (8) located on or adjacent the weapon to produce a visual indication (P) on the screen (3) by a projected beam of visible light, of at least a final portion of the flight path of the simulated fired projectile or missile, corresponding to the position at which the weapon was aimed when fired, for a projectile or missile whose trajectory or flight path cannot be controllably varied after firing, or corresponding to the position at which the weapon was aimed when fired and as subsequently controllably varied, for a projectile or missile whose trajectory or flight path can be controllably varied after firing. The or each target image projector (4) is located in the structure at the centre of curvature of the concave truncated spherical shaped screen (3) and mounted for universal movement on a gimballed mounting (5) providing two axis freedom of movement. The visible light projector (8) is a laster projector. An infra-red projector (9) may be included to project a beam of radiation along the line of sight of the weapon together with a detector (10) for this beam. The projector (8) may be operable to indicate visually on the screen (3) the impact of a missile or sequence of projectiles on the target image (T) and/or the whole of the flight path of the missile or projectile.</p> |
