Device for simulating shots for direct shot

Weapon systems with a high-power laser in their fire control system for Distance measurement is integrated.

The invention relates to a device for simulating shots, of weapon systems that require a fire control system to operate successfully which contains a range finder, e.g. a Nd: YAG laser, as a component.

The well-known simulation of shots by means of lasers, which to this function is also used on the main battle tank or other flat fire weapon systems are adantiert, is here with the existing laser for distance measurement carried out for the real fire fight. To do this are certain measures and technical Facilities required to achieve the objective of simulating gunfire such as tactical Training of the teams and a high degree in shooting training with the for to achieve another purpose intended and existing laser device.

This goal is based on existing fire control systems such as the laser, the measuring receiver for determining distance and the evaluation electronics according to the invention is used with a comparatively extremely low Effort to achieve.

Shooting simulation devices equipped with lasers are known are. These lasers emit light outputs below the eye damage limit, so that there are no dangers for participants. The output power is approx. 5 powers of ten below those of known distance measuring lasers in Fire control systems e.g. of battle tanks. It is also known to have reflectors at the target to attach that reflect this low light output and thus on the shooting Weapon system to determine whether the target has been hit.

Likewise, it is known that aryl target receivers are attached to the Laser signals of the firing weapon system received and if the laser light simultaneously Information is given to recognize this and thus to receive information.

The disadvantage of this state of the art is that it occurs in real combat used laser not used and therefore not the special handling of this laser is practiced, the original controls of the fire control system are not used and an avoidable high technical effort is required.

The invention is based on the object of avoiding these disadvantages and to greatly reduce the effort with which this goal is achieved.

In the case of the device according to the invention, this is initially high Eye-damaging laser light from the high-power laser integrated in the fire control system by a before placed absorption filter on an eye-harmless one Measure, or reduced to a very small safety area. The power level is then still relative in comparison to known shooting simulation devices high, because the laser light consists only of a single light pulse, or a from 0 m different security areas <: h is accepted what by the absorption coefficient of the filter is determined.

This means that the high-power laser is prepared for practice use.

Since the divergence of the distance measuring laser of fire control systems is very is small (e.g. 0.4 mrad) in order to avoid unnecessary false echoes in real use, the effective beam cross-section is normally essential for all target distances smaller than the target area. For this reason, the target must be tightly sealed with reflectors be occupied that have such a small distance from each other that even if if the tent is in relative proximity (e.g. 500 m) one of the reflectors is hit will. However, this requirement means that? the reflectors are an essential part Represent a cost factor and equipment e.g.

with triple prisms suitable for small targets not for large targets it makes sense that for an armored turret z.ti.

approx. 25 triple prisms would be required. Therefore either with Retroreflective sheeting or other simple but poorer performance Retroreflective material worked, as they are known from P 29 36 012.1-51. on the other hand is the zone in which the target must be retroreflective on a high, to limit the horizontal ring zone, as this can be expected when shooting Fnzuzlelen and the reflectors also effective in the so-called partially covered position must be, so that the part of the target that is not in partially covered position visible is also not occupied with reflectors.

This ensures that in the case of a greatly reduced safety zone the Distance measuring lasers can be used for exercises chin.

The usability as S device for simulating shots is according to the invention achieved by a laser pulse again by pressing the shot button is sent out, and thus the following in the fire control system of the firing weapon system Information is available: 1. Measured value for the distance before the shot was released.

2.Receive reflection signal when the shot button is pressed, which means that the target was correctly positioned when the shot was fired and thus 3. the target distance when firing a shot.

Furthermore, this information about the distance, which existed in the fire control system before the shot was fired and the distance that was present when the shot was fired electronically compared with each other and information generated as to whether the difference both distances are smaller than what would just be allowed for a hit.

These are the distance-dependent areas where the ammunition hits electronically stored.

This electronic test process can be used to decide whether the shot would have resulted in a hit. Is the difference between the two distances outside the hitting area - if the attachment angle were set incorrectly - would be be a fur shot.

This means that the information on whether a hit or not is at the closing point Vehicle in front.

This information must be used as a device for simulating gunfire to be complete according to the invention be transmitted to the destination, in order to ensure there in a known manner that no more simulated ships can be given, i.e. to make the ifblng partner incapable of action.

Since the target is already aimed relatively precisely by the shooter and the information on whether a hit or not is available electronically in a very short time stands (in the nillisecond range), the transmission can according to the invention by means of a Line of sight adjusted information transmission laser happen. The divergence of the laser beam is chosen so large that a receiver at the target the information receives safely and no special requirements sn the location of the or the Recipients.

Significant advantages are achieved with the described facilities: - Extremely cost-effective device to achieve the target to simulate shooting, de ground components that are largely present in the fire control system.

- Exact requirements for the accuracy of shot firing (such as Laser divergence).

- Original controls are used.

- The laser in the fire control system (usually the one for training purposes switched off) can be used to measure the distance and thus the entire process the shooting procedure can be practiced as in the real case.

- Little installation effort for the facility.

- Compatibility with other existing simulation devices achievable through additional laser information transmission.

An exemplary embodiment is described below with reference to the accompanying drawings for the simulation device according to the invention.

As an example, a battle tank (3) (Fig.1) is chosen, which has a independent Vi sier line, whose cannon is tracked and in which Fire control system a high-performance range laser is integrated.

Fig.1 shows the attachment of the large-area reflectors (2) in height the center of the tower. Lens reflectors are shown here. On the tower roof is a Receiver (1) mounted, which receives the laser radiation from the information transmission laser (6) received from all sides k. nn, however, is not always able to use the much smaller surface Laser radiation of the Distance measuring laser (4) to receive.

Fig.? shows the laser attenuation filter (6) in front of the exit window (7) the optical sight. The high-power laser (8) transmits the laser light the stabilized mirror (9) weakened by the filter (6) to the target. That reflected Laser light bundle (10) is via the mirror (9) and spectral beam splitter (11) shown on the distance measuring receiver (12).

The distance is measured in the electronics of the fire control system (13) and displayed on the crew's display device (14). The removal can, however can also be entered. In the control unit of the simulation device (is) the distance entered and saved via an additional cable connection (16) to compare this with the distance measured when the shot was fired can.

In the event that the hit area is not exceeded, the information transmission laser (21) controlled so that the hit information is sent to the target. Not with the recipient (18) the hit information is received. The activity tests () for the distance measuring laser remains unchanged.

The signal from the button for firing the shot (20) is over put the control unit of the simulation device on the laser button. On this one "Hit" or "Hit" is displayed on the control unit.
