A training apparatus for aiming and gunnery comprises a target tracer, a central control and monitoring unit and equipment at each of a plurality of anti-aircraft guns or other weapons for combatting moving targets. The target tracer is provided with a range finding radar and a TV camera which, by means of an aiming instrument, are continuously held aimed at a moving target. Furthermore, the target tracer has rotational position indicators for indicating the positions of the radar and the camera with respect to a horizontal and a vertical axis. From information obtained from the radar and the indicators, a data processing unit in the central control unit calculates the correct aiming allowance point for each of the weapons, which points can be shown, on the one hand, one at a time on a common TV monitor, and, on the other hand, on a separate TV monitor for each weapon. In both cases, the field of view observed from each respective weapon by means of TV cameras mounted on the weapons, is overlaid on the TV monitor in question, such that on correct aiming of the weapons, the displayed aiming allowance point coincides with the image of the moving target. For checking that the tracing of the target is effected accurately, use is made of the image, obtained from the TV camera of the target tracer, on the common TV monitor.
Training apparatus for aiming and firing at moving actual targets with a plurality of weapons intended for such targets, said apparatus comprising a target tracer (1) and an associated data processing unit (11) for deriving magnitudes representing the requisite aiming allowance point of each respective weapon from signals received from the target tracer which indicate range and direction to the target at different points of time, i.e. target parameters, and from magnitudes which represent the performance and position of the weapon, i.e. weapon parameters, a TV camera, (3.sub.1, 3.sub.2, . . . 3.sub.n) arranged in parallel with a direct aiming sight of the weapon and mounted on each weapon, a mixer unit (10) and a TV monitor (9), said TV camera being connectible, by the intermediary of said mixer unit (10) to said TV monitor (9) common to the weapons, whereby a signal corresponding to the magnitude representing the aiming allowance point of each weapon is combinable in said mixer with the video signal emanating from the TV camera of the weapon for supply to the TV monitor.
