Abstract

Detonating projectiles are fired into a target area by a weapon, the time between firing and detonation being one second or less. By setting the target location at the same distance as e.g. the edge ( 1 ) of a building ( 3 ), however laterally displaced with respect to that edge, it is possible to obtain an effect also in an area invisible to the bearer of the weapon. For simulating this weapon, for example in house-to-house fighting, it is proposed to affix devices ( 5 ) comprising a sensor ( 22 ) and a transmitter ( 27 ) to obstacles. When the weapon is fired, a simulation device provided on the weapon transmits a firing signal to the sensor ( 22 ), the latter activating the transmitter ( 27 ). Similarly to the real effect of the weapon, the transmitter ( 27 ) emits an impact signal in the impact area ( 7 ) which also includes the mentioned area which is invisible to the bearer of the weapon. On account of the independent operation of the transceiver unit ( 5 ), it is possible to simulate the effect of this weapon substantially without delay as compared to reality.

Description

The present invention relates to a method for Simulation of the effect of exploding projectiles according to The preamble of claim 1. Furthermore, the Invention on a device for carrying out the Process according to the preamble of the first Apparatus claim.

A well-known kind of detonating projectiles are those of ballistic weapons (mortars, Guns) are fired. For the simulation will be off the gun alignment and other parameters the trajectory and the detonation point calculated. Because of the relative long flight time of several seconds, this calculation be performed by a central computer.

DE 198 03 337 A1 discloses a method for simulating the threat of subscribers military exercise known by hand grenades or mines. It serves for realistic simutation the threat of practice participants; especially soldiers and vehicles, through individual mines, Mine locks and hand grenades.

Recently, however, there are also infantry weapons, the after work this principle. Essentially it acts this is a gun-like weapon. The shooter aims For example, on a wall edge of a house. The Target device determines this distance and stores it. The shooter then aims past the wall corner and releases the shot out. The projectile flies the previously determined Track and detonate at their end point or even one certain distance before or behind it. Essentially It makes it possible to hit behind the targeted one To achieve a corner. Simply put, it is possible to a certain extent "around the corner".

Since in particular the time of flight with this weapon rather in the Range of milliseconds, it is not possible the Effect of this weapon through a central computer too simulate without a delay far from reality between shot firing and effect to have to accept.

An object of the present invention is therefore to to provide a method to the effect of detonating To simulate projectiles where between launch and Detonation at the destination close to reality low delays occur.

Such a method is specified in claim 1. The Further claims give preferred embodiments as well Devices for carrying out the method.

The inventive method is characterized according to the Main aspect by being one of the ones to be simulated Weapon emitted firing information recorded locally and in the Area of action of the simulated detonation broadcast , especially in the area covered by the Position of the shooter is not visible. Prefers This happens because of the fact that at the obstacle Transmitter receiver unit is present. The recipient of this Unit takes the information sent by the weapon on the successful launch and activates the Transmitter unit, the information in the area of action over the simulated detonation sends out. In this Area of action participants in the exercise, the have corresponding receiver, are about it inform that they are taken and out of the exercise retire or be considered injured.

In a preferred embodiment is in addition Determined from which direction the weapon on the Obstacle is directed to the action space of the detonation be able to pinpoint more accurately. More preferably then points The sender unit also has the option to target only certain areas of the possible hit area with the Impact signal to brush.

The invention will be further explained with reference to an embodiment with reference to figures.

At a wall corner 1 of an indicated house 3 is a Transmitter receiver unit 5 according to the invention. she will be referred to as SE unit for short. It is still Note that the SE unit 5 in relation to simulated detonation-effective space 7 oversized is drawn.

The aim of the simulation is to increase the effect of a projectile simulate flying along trajectory 9 and at point 10 detonates. Idealizing is believed to be the explosion at point 10 an effect in room 7 unfolds. The trajectory 9 is flat. A prerequisite for the simulation is that the appropriate weapon with a device equipped, which are visible in the weapon Target area shot information radiates. Usually this is a simulation device with Laser source. The known versions of these devices already have the ability to reserve and essay too Compensate by the laser beam against the Target direction laterally and / or in height deviating in the Target area is radiated. For explosive projectiles and Other applications it is known with the Laser device in the targeted area a larger area For example, the laser beam zigzags to guide over a given area to detectors in the Equipment of devices and exercise participants in the Activate area of action.

In the simulation of the underlying weapon is first the wall corner 1 anvisiert. The laser beam of Simulation device on the weapon hits the SE unit 5. The receiver present therein is thereby if necessary, put in an alarmed state. Of the Receiver is sensitive to direction, at least approximately to determine the direction of trajectory 9. The SE unit moreover, has a reflection device 20 which reflects the laser beam back on itself. Thereby Is it possible for the target device to determine that you are Ray has hit an SE unit 5. When aligning the Weapon on the destination 10 can then the target device Laser beam so with respect to the orientation of the weapon swivel or widen that he is still the SE unit 5 hits.

When triggering the weapon becomes over the laser beam one corresponding information to the receiver of the SE unit transfer. This then activates transmitter part 27 of the SE unit 5, which in the action area 7 the hit signal radiates. In the present example it is assumed that the area of action 7 essentially represents an ellipse, whose longer axis is perpendicular to the trajectory 9. Devices and / or simulation participants who are in the Area 7 are located and detectors for the signal of the Transmitter of the SE unit 5 carry, so immediately with Trigger the shot by activating its sensors informed that they are the effect of this weapon are exposed.

In other words, the SE unit 5 sets the Effect signal from the simulation device of the weapon is emitted in a order that the hit area 7 covering, even where the hit signal of the weapon even for physical reasons can not get it.

Figures 2 and 3 show the SE unit 5 greatly enlarged. It basically consists of three parts: located at the top the reflection part 20. He serves to that of the weapon reflected laser signal to reflect back on so that the weapon can locate the SE unit 5.

In the middle is the sensor 22. It consists of a number of sensor elements 24, each one sector monitor. The horizontal (virtual) trajectory 9 can for Examples in the division according to Figure 2 with a Resolution of 45 degrees can be determined. The sensor elements 24 may be conventional photosensitive elements that are shielded from each other by partitions 26 to the receive sector-shaped directional characteristic.

At the bottom of the SE unit 5 is the transmitter 27. Er consists of a number of transmitter elements 29, each in covering about one sector of the environment of the SE unit. In addition, controls not shown, the SE unit 5, the transmission power of the transmitter elements 29, by the range of the radiated from the transmitting elements To control the effect signals and thus the shape of the Reproduce area 7.

The control of both the simulation device on the weapon as well as the SE unit 5 is by common means realizable. For example, with each sensor element 24 a threshold amplifier to be connected when receiving a signal responds. He causes everyone Transmitter element is supplied with energy of a certain height, 5 whereby the range of the effect signal in this direction is set. This will be a form of Impact area 7 modeled after the alignment of the respective sensor element 24 and thus the trajectory. 9 equivalent.

Control devices for this purpose are without the expert more accessible and therefore do not need further Detail will be explained.

Another possibility of controlling the SE unit 5 is the respective house 3 with one enough to equip powerful simulation computer that the monitored by the SE units, possibly also only in the environment of the house triggered weapons, especially the simulated type, determined and the corresponding Transmitter units 20 triggers. It is in this arrangement additionally possible, more, not in the SE units to provide integrated transmitter units and / or in the Range of action of each weapon located participants or equipment, for example via radio individually over theirs To inform the area of residence in the sphere of influence. There this local arithmetic unit in principle also at any time Place and number of all participants in their vicinity, Equipment and weapons is informed, it can be complementary to the local SE units 5 the use of the weapons too then simulate, if not according to their actual Purpose, for example in direct fire, which may not be recognized by the SE units 5 can be. However, depending on this is with a certain Delay and thus lesser proximity to reality in the To calculate hit simulation.

Starting from the preceding description of a preferred embodiment are those skilled in the art modified versions accessible without the scope of Invention as defined in the claims to leave. To the Example, it is possible to lower claims on the Directional sensitivity of the transmitter 27 as well as the sensor 22 to give up. Is the transmitter 27 on the Range control and especially on the Directivity omitted, so is a substantially circular area of action surrounding the SE unit simulated. A waiver of any directivity of the Although sensor unit could still be tolerated in extreme cases However, then the SE unit could not be more distinguish whether the special weapon as intended is used and, for example, directly on the obstacle In any case, a proper would Use of the weapon assumed.

Instead of light (laser) could also be to other means of Data transfers are thought of, such as Ultrasound or radio signals, in particular of high Frequency, for example 2.4 GHz. Generally, however, are suitable the latter because of their sensitivity to certain Weather conditions, which are actually the course of the Simulation should not significantly hinder, less well.
