Abstract

The invention relates to a method for simulating a battlefield, whereby real , armed, participants (11), acting on a training range which represents the battlefield, fire simulated shots at targets (12) located on said training range. The hits on the targets (12) which are located in the action zone are transmitted from the hypothetical projectile impacts of the simulated shots. In order to avoid the disadvantages of conventional methods of battlefield simulation which operate with laser light, a central unit (14) maintains exclusive radio contact with the participants (11) and targets (12) and all data relevant to the shooting simulation is exchanged via said central unit (14).

Description

Method for Simulating a Battlefield The present invention relates to a method of the type defined in the preamble to Patent Claim l, for simulating a battlefield.
The objective of such a battlefield simulation is to reproduce real combat situations on a spatially limited training area and thereby permit tactical training. All the manoeuvres are monitored from a central unit, and intervention in the combat situations is possible, should this be necessary.
Depending on the combat situation, the combatants and the targets can exchange roles, so that the targets can then deliver fire power and the combatants become targets that are shot at.
In one known method for simulating a battle field, in particular for representing the battle-field data that are generated (DE 40 26 207 A1), at least two vehicles, preferably armoured vehicles that are taking part in a military exercise, are each equipped with a dual simulator that determines combat and operating data, for example, the results achieved by gunnery and the hits obtained, quantities of ammunition, and the operational status of the vehicle. In order to permit an immediate and ongoing assessment of the situation of all vehicles taking part in the exercise, and do this in the form of a general overview in a central assessment centre, the vehicles are in radio contact with the central unit and transmit their position data, as well as the combat and operating data ascertained by the dual simulator, to the central unit, where a computer assesses these data in order to represent intermediate and/or end results and/or an overview of the complete situation.

In a known system for combat simulation with combatants, e.g., armoured vehicles, that are moving about within a training area, (US 5 382 958), a central combat command unit activates a plurality of relay stations that are distributed throughout the training area by radio. Each relay station receives information with respect to position and time from a GPS.
Each relay station repeatedly sends position information about the battle field within a time frame, and selected relay stations also send gunnery information that includes the type of ammunition, range, and effect. Using the information received from at least three relay stations, the combatants can determine their position relative to a point of impact that has been transmitted.
US 4 744 761 describes a system that simulates the effectiveness of indirect fire, e.g., artillery fire, in which-depending on the type of ammunition selected and a selected target-control signals and, depending on the controls signals, a multitude of radio waves are transmitted to the target area and an indication is provided as to what in the selected target area has been hit by the type of ammunition fired. To this end, a master station is positioned close to the gun that is firing, and close to the target area there is a plurality of remotely controlled substations as well as displays that are associated with a plurality of objects located within the target area. The master station communicates by radio directly with the substations and, in their turn, the substations emit radio waves that are received by the display units within the target area. Within the display units, a decoding device determines whether on not the object that is linked to it has been hit or not.
One known battlefield simulation system (US S 788 500) uses a laser for simulating shot, and this emits a laser light continuously (CW laser). The laser light is modulated by pulse code modulation (PCM) and pulse pause modulation (PPM) so that both the combatant who fires the shot as well as the type of weapons system firing to shot can be identified unequivocally. All the combatants are equipped with optical sensors to receive laser light. A
combatant that has been shot at receives the information modulated onto the laser light by way of its optical sensors and from this derives an appropriate result, e.g., a hit or a miss and/or a representation that shows the effect of a hit.
More costly simulators, which are preferably used for tube-type weapons, e.g., tanks, use the laser light of the shot simulator to range the target prior to a shot being fired, to which end the target is additionally fitted with reflectors that return the laser light. The range to the target and the position of the hit relative to the reflector can be determined, and these are then transmitted to the target.
Shot simulators that are based on laser light have various disadvantages. The optical sensors have to be attached to the outside of the combatants in such a way that said combatants can be engaged from any direction. During the battle exercise, steps must be taken to ensure that no sensor is covered over, e.g., by dirt. There must be an unobstructed optical transmission path between the target and the combatant that is delivering fire. Determination of the hit position by the firing combatant is extremely costly, and it is impossible to separate a target from a plurality of such targets that are being painted simultaneously by the laser. The range of the shot simulation is limited because the laser light must not be hazardous to the observers' eyesight.
It is the objective of the present invention to describe a method for battlefield simulation that avoids the disadvantages set out heretofore.
This objective has been achieved by the features set out in Patent Claim 1.
The method according to the present invention entails the advantage that radio transmission of data is largely immune to interference and is not shielded by terrain features, so that the requirement for an unobstructed field of fire is eliminated.
The danger of becoming contaminated is slight both for the sender and the receiver of the radio transmission and, unlike the case of when lasers are used, no special measures to protect the combatants are needed. Furthermore, targets located behind cover, for example, targets concealed by buildings or dense vegetation and trees, which cannot be hit by a laser shot, can also be destroyed, because the actual beam of laser light always travels to the target on a direct path, whereas an actual shot, e.g., one fired from a tube-type weapon, follows a parabolic trajectory.
In the event that several targets are located in the area of the fall of shot, separation of the targets is simple, and the different effects of shot impact on the various targets are displayed.
Useful embodiments of the method according to the present invention, with advantageous developments and configurations of the present invention, are set out in the secondary claims.
In one preferred embodiment of the present invention, the current position of each combatant and each target are continuously reported to the central unit and then, within the central unit, are input into a training area data base that contains position data referring to fixed objects such as houses, walls, streets, stands of trees, and the like. Thus, the central unit has a continuously updated overview of the combat situation and all of the combatants and targets involved in combat.
In a preferred embodiment of the present invention, each target-and preferably each combatant and each target, since the two can exchange roles-has a data base that contains ballistic tables for all the weapons systems being used in the training area, such data bases also including the types of ammunition they fire, and with models for the type and degree of casualties or damage caused by a hit, as well as characteristics that identify the combatant or the target. Thus, the targets have what is needed to compute hits and to determine the effect that the hits will have on a particular target.
According to one preferred embodiment of the present invention, hypothetical falls of shot are determined in the central unit using the data sent by the firing combatant, and with the help of the ballistic tables that are in memory, and only the targets that are endangered by their position within the effective area of the fall a shot are addressed from the central unit in order to exchange data. When this is done, on the basis of the data base for the training area that is stored in the central unit, cover that is offered by buildings or trees in the direction of the target is also taken into account. The number of combatants and targets communicating with each other simultaneously is reduced to a minimum by this procedure.

According to one preferred embodiment of the present invention, when a simulated shot is fired by a firing combatant, the shot data such as direction, elevation, lead, and position of the firing weapon, the type of weapon and type of ammunition, as well as identification of the combatant delivering the fire is sent to a central unit and these shot data are transmitted from the central unit to the targets that are endangered, and these in their turn recalculate the position of the hypothetical fall of shot and inform the central unit of this together with the identification of the reporting target. Based on the computed position of the fall of shot and their own positions and movement at the time of impact, the targets determine the type and degree of their casualties or damage, and report this information to the central unit. In the event that the target position and the position of the hypothetical impact agree with respect to time and position, a hit is indicated visually and/or reported to the central unit.
The present invention will be described in greater detail below on the basis of embodiments shown in the drawings appended hereto. These drawings show the following:
Figure 1: elements of a battle field with an actual combat situation;
Figure 2: a block diagram showing the battle field simulation method.
Figure 1 shows elements of a training area that is being used as a battle field in which armed combatants 11, for example, troops, tanks, guns, and the like, are in action and fire simulated shots at passive combatants hereinafter designated targets 12, which are, for instance, troops, tanks, guns, vehicles, and the like. In the embodiment shown in Figure 1, a tank is shown as an armed combatant 11, and a truck that is moving across the terrain is designated as target 12. In the event that the targets 12 also have a weapons system at their disposal, then they can exchange their roles at during the battle, so that target 12 is now the combatant delivering fire and the armed combatant 11 now represents the target. All combatants 11 and targets 12 are equipped with a satellite-supported positioning apparatus, e.g., GPS or DGPS, which continuously determines the positions of the combatants 11 or of the targets 12, and with a computer unit and with a data bank and or data base (Figure 2) that contains ballistic tables for all of the weapons systems in use on the battlefield, statistical information relevant to all of the weapons system in use on the battle field, and models for the type of possible casualties or damage that will be caused in the event of a hit. Both the combatants 11 and the targets 12 possess radios with which they can communicate with the central unit 14. Radio communications between the central unit 14, the combatants 11, and the targets 12 are indicated by the arrows 15 shown in Figure 1. The central unit 14, which is similarly equipped with a radio, also has a computer unit with a terrain data base 16 that contains the positions of fixed objects in the terrain, such as houses, walls, roads, trees and the like, and a data base 17 which-as the in the case of the targets 12 and armed combatants 11-contains ballistic tables for all the weapons system being used in the training area, including information about the types of ammunition used by these.
During a combat exercise, all combatants 1 l and all targets 12 continuously report their actual positions as provided by the GPS (x, y, z coordinates of battle tanks and trucks in Figure 1) to the central unit 14, which stores them in the terrain data base 16; these stored variables are continuously updated. In the event of a simulated shot being fired by a combatant 11 , the firing data, such as the position of the weapon 18 that has been fired (x, y, z coordinates in Figure 1 ), the alignment of the weapon (elevation E, lead ~), type of weapon, type of ammunition, and the identification of the combatant 11 that is firing are all sent to the central unit 14. Using these firing data, the hypothetical, simulated, or virtual trajectory and the hypothetical fall of shot are determined in the central unit 14 with the knowledge from the data base 17.
The firing data are transmitted from the central unit 14 to those targets 12 located within the area affected by the hypothetical fall of shot as computed by the central unit 14, which could be hit or damaged, which is to say, which could be endangered. The hypothetical fall of shot is again determined by the endangered targets 12 using the firing data about the firing combatant that have been transmitted and the knowledge from the data base 13; when this is done, their own movement, and the direction of such movement during the flight time of the projectile are taken into consideration. If their own position and the hypothetical fall of shot agree by time and position, the target provides a visual indication of a hit; this can be done, for example, by emitting a flash 19, as is shown in Figure 1. At the same time, the hit is reported to the central unit 14. If no direct hit is identified, but the position of the target is only in the immediate vicinity of the fall of shot, the type and degree of possible casualties or damage to the target 12 is determined using the knowledge obtained from the data bank, and then reported to the central unit 14.
