Abstract

The simulation device provides training in the firing of rockets or guided missiles by means of a shoulder weapon. As soon as a shot is fired, the firer's field of view is occulted by a shutter. The aim at the instant of firing and the point of impact with respect to the target are displayed on an instructor's video screen. The target can be of a fictitious type generated by a computer and produced within the field of view of both the instructor and the firer at the same time. In the case of a real target, an index can be controlled by the instructor in order to locate the target and follow its progress up to the instant of firing. The result of the firing operation is judged according to the position of the point of impact with respect to the fictitious target or with respect to the index. The choice of the mode of operation is made on a control desk.

Description

La présente invention concerne un dispositif de simulation destiné à l'entraînement à la manoeuvre d'armes épaulables, telles que celles qui servent au tir de roquettes ou de missiles auto-guidés, ou à la manoeuvre d'armes analogues.The present invention relates to a simulation device intended for training in the maneuvering of shoulder weapons, such as those which are used for launching rockets or self-guided missiles, or in the maneuvering of similar weapons.

Des dispositifs de simulation pour l'entraînement au tir sont déjà connus et largement répandus. Ils servent à la formation et à l'instruction des tireurs en leur permettant, en salle ou sur un terrain réel, de s'entraîner au pointage d'une arme sur une cible, sans pour autant faire réellement consommation de projectiles. Le projectile est un projectile fictif, dont un calculateur permet de définir la position pour la comparer avec celle de la cible et apprécier la qualité du tir, en déterminant en particulier si le pointage est correct pour conduire le projectile simulé à un impact sur la cible. Ces dispositifs de simulation sont sans cesse perfectionnés pour reproduire au mieux les conditions des tirs réels, de sorte que les tireurs ne soient pas dépaysés lorsqu'ils passent de l'entraînement en simulation de tir au tir avec des projectiles réels. Toutefois, on s'est surtout intéressé à ce jour à l'entraînement au tir à partir de chars ou d'autres postes de tir analogues. Un dispositif connu selon le brevet français 2 191 715 déposé par la Demanderesse comporte une arme à axe de visée orientable par le tireur, des moyens optiques pour présenter à l'observation du tireur un champ de vision comprenant un terrain de tir et une cible, des moyens de déclenchement d'un tir fictif de projectile par le tireur et des moyens pour déterminer le point d'impact du projectile dans le plan de la cible. Les dispositifs connus de ce type, conçus pour les armes imposantes, telles que canon de char, conviennent bien moins au cas des armes épaulables. La différence est que dans une campagne de tir réel, le tireur reste en place devant son arme dans le cas d'un canon de char, alors que dans le cas d'armes épaulables comme les lance-roquettes, le tireur lache son arme aussitôt le coup parti et il peut même s'en séparer au plus vite en l'abandonnant.Simulation devices for shooting training are already known and widely used. They are used for training and instructing shooters by allowing them, indoors or on real ground, to practice aiming a weapon at a target, without actually making use of projectiles. The projectile is a fictitious projectile, a calculator of which makes it possible to define the position in order to compare it with that of the target and to assess the quality of the shot, in particular determining if the aiming is correct to drive the simulated projectile to an impact on the target . These simulation devices are constantly being perfected in order to reproduce the conditions of real shots as well as possible, so that the shooters are not disoriented when they go from training to shooting simulation with real projectiles. However, most attention has been focused to date on tank training or similar shooting positions. A device known according to French patent 2,191,715 filed by the Applicant comprises a weapon with a line of sight which can be oriented by the shooter, optical means for presenting a field of vision to the shooter's observation comprising a shooting range and a target, means for triggering a fictitious projectile shot by the shooter and means for determining the point of impact of the projectile in the plane of the target. Known devices of this type, designed for large weapons, such as tank guns, are much less suitable for shoulder weapons. The difference is that in a live fire campaign, the shooter remains in place in front of his weapon in the case of a tank cannon, while in the case of shoulder weapons such as rocket launchers, the shooter immediately releases his weapon the shot started and he can even part with it as quickly as possible by abandoning it.

La présente invention répond au souci de mieux adapter les dispositifs de simulation de tir du genre ci-dessus à l'entraînement à la manœu- vre de lance-roquettes de lanceur de missiles auto-guidés ou d'armes analogues, en permettant de placer l'opérateur dans des conditions très proches de celles qu'il sera amené à rencontrer dans les tirs réels. Et dans ce but, il est proposé de munir le dispositif de simulation de moyens d'occultation commandés pour cacher le champ de vision du tireur aussitôt le coup parti, évitant ainsi de donner au tireur la fâcheuse habitude de rester sur place pour voir le résultat de son tir et d'être ainsi vulnérable à une riposte éventuelle.The present invention responds to the concern to better adapt the firing simulation devices of the above kind to training in the maneuvering of rocket launchers for launchers of self-guided missiles or similar weapons, by making it possible to place the operator in conditions very close to those he will encounter in live fire. And for this purpose, it is proposed to provide the simulation device with concealed means controlled to hide the field of vision of the shooter as soon as the shot is started, thus avoiding giving the shooter the annoying habit of staying put to see the result. of his shot and thus being vulnerable to a possible response.

L'invention a donc pour objet un dispositif de simulation pour l'entraînement à la manoeuvre d'armes comprenant :

  • une arme à axe de visée orientable par le tireur,
  • des moyens optiques et électroniques pour présenter à l'observation du tireur un champ de vision comprenant un terrain de tir et une cible,
  • des moyens de déclenchement d'un tir fictif de projectile par le tireur,
  • un calculateur pour déterminer la position d'impact du projectile dans le plan de la cible à partir des données préalablement enregistréesi
  • un poste d'instructeur ayant des moyens de visualisation présentant le champ de vision à l'observation d'un instructeur,

caractérisé en ce que
  • ladite arme est une arme épaulable sur laquelle sont montés lesdits moyens optiques et électroniques,
  • les moyens optiques et électroniques comportent des moyens d'occultation pour éclipser le champ de vision de la vue du tireur lors du déclenchement du tir et des moyens de transmission pour transmettre une image dudit champ de vision aux moyens de visualisation du poste de l'instructeur,
  • les moyens de visualisation comportent un écran pour visualiser le champ de vision transmis ainsi que la position calculée d'impact par rapport à la cible.
The subject of the invention is therefore a simulation device for training in the handling of weapons comprising:
  • a weapon with an aiming axis adjustable by the shooter,
  • optical and electronic means for presenting to the shooter's observation a field of vision comprising a shooting range and a target,
  • means for triggering a fictitious projectile shot by the shooter,
  • a computer to determine the impact position of the projectile in the target plane from previously recorded data
  • an instructor station having display means presenting the field of vision to the observation of an instructor,

characterized in that
  • said weapon is a shoulder weapon on which said optical and electronic means are mounted,
  • the optical and electronic means comprise concealing means for eclipsing the field of vision from the view of the shooter when the shooting is triggered and transmission means for transmitting an image of said field of vision to the display means of the instructor's station ,
  • the display means include a screen for viewing the transmitted field of view as well as the calculated impact position relative to the target.

Dans la mise en oeuvre du dispositif de l'invention, on peut utiliser aussi bien une cible réelle qu'une cible fictive. Dans le premier cas, les exercices sont effectués sur un terrain de tir dans lequel se trouve une cible, généralement mobile. Dans le second, le dispositif comprend des moyens de formation d'une cible fictive apparaissant dans le champ de vision du tireur en superposition sur le terrain de tir. Ces moyens peuvent être par exemple du type de ceux qui ont été décrits dans la demande de brevet déposée par la demanderesse le 12 juin 1981, sous le numéro 81 11574 et publiée le 17 décembre 1982 sous le numéro FR-A-2 507 764 correspondant à EP-A-0 068 937. Ils permettent de visualiser devant le tireur et devant l'instructeur une représentation réaliste, non ponctuelle, d'une cible en évolution. Naturellement, dans un cas comme dans l'autre, la cible n'est pas nécessairement unique et l'invention s'applique aussi bien à des exercices sur cibles multiples.In implementing the device of the invention, it is possible to use both a real target and a fictitious target. In the first case, the exercises are carried out on a shooting range in which there is a target, generally mobile. In the second, the device comprises means for forming a fictitious target appearing in the field of vision of the shooter superimposed on the shooting range. These means may, for example, be of the type described in the patent application filed by the plaintiff on June 12, 1981, under the number 81 11574 and published on December 17, 1982 under the corresponding FR-A-2 507 764 number. to EP-A-0 068 937. They make it possible to visualize in front of the shooter and in front of the instructor a realistic, non-punctual representation of an evolving target. Naturally, in one case as in the other, the target is not necessarily unique and the invention applies equally well to exercises on multiple targets.

Les moyens d'occultation sont avantageusement constitués de manière que lorsqu'il s'agit d'une cible fictive, cette cible se trouve figurée dans le champ de vision du tireur en même temps que le terrain de tir, mais de manière à laisser subsister cette cible fictive sur l'écran du poste d'instructeur à l'occultation du champ de vision du tireur. L'instructeur est ainsi en mesure d'apprécier le résultat du tir d'après la position qu'occupe le point d'impact par rapport à la cible fictive au moment où le projectile fictif est supposé atteindre le plan de la cible. Seul le terrain de tir disparaît de son écran lorsque le tireur déclenche le tir et il peut encore voir le point d'impact et la cible fictive qui sont incrustés sur son écran par des moyens électroniques commandés par le calculateur.The concealment means are advantageously constituted so that when it is a fictitious target, this target is found in the field of vision of the shooter at the same time as the shooting range, but so as to allow to remain this fictitious target on the instructor station screen when the shooter's field of vision is obscured. The instructor is thus able to assess the result of the shooting based on the position occupied by the point of impact with respect to the fictitious target at the time when the fictitious projectile is supposed to reach the plane of the target. Only the shooting range disappears from his screen when the shooter starts shooting and he can still see the point of impact and the fictitious target which are embedded on its screen by electronic means controlled by the computer.

Dans le cas où la cible est une cible réelle, comprise dans le champ de tir, qui s'éclipse donc du champ de vision en même temps que le terrain, il est avantageux que le dispositif mette à la disposition de l'instructeur un index de repérage de la cible, pilotable du poste d'instructeur et visualisé sur l'écran correspondant. Un tel index permet à l'instructeur de poursuivre la cible tant qu'elle est visible dans l'image projetée du champ de vision du tireur et ensuite, après le déclenchement du tir et l'occultation, de conserver une indication de la position de la cible par cet index qui reste visible sur son écran. On utilise de préférence un index présentant un contour non ponctuel et pilotable aussi bien en position qu'en dimensions.In the case where the target is a real target, included in the shooting range, which therefore disappears from the field of vision at the same time as the ground, it is advantageous that the device makes available to the instructor an index target location, controllable from the instructor station and displayed on the corresponding screen. Such an index allows the instructor to pursue the target as long as it is visible in the projected image of the shooter's field of vision and then, after the launch of the shot and the occultation, to keep an indication of the position of the target by this index which remains visible on its screen. It is preferable to use an index having a non-punctual contour which can be controlled both in position and in dimensions.

La figure 1 est une vue d'ensemble d'un dispositif de simulation selon l'invention utilisé pour l'entraînement au tir de roquettes à partir d'une arme anti-char épaulable. Celle-ci est illustrée par un tube lance-roquettes 6 unique, bien que le dispositif puisse en comporter plusieurs, suivant le nombre de tireurs à entraîner dans une même séance. Le cas particulier considéré n'est pas restrictif, non plus, en ce qui concerne le type d'arme, le tube 6 pouvant être plus généralement un lanceur de projectile et le projectile pouvant être par exemple un missile aussi bien qu'une roquette.Figure 1 is an overview of a simulation device according to the invention used for training in firing rockets from a shoulder anti-tank weapon. This is illustrated by a single rocket launcher tube 6, although the device may include several, depending on the number of shooters to train in the same session. The particular case considered is not restrictive, either, as regards the type of weapon, the tube 6 possibly being more generally a projectile launcher and the projectile possibly being for example a missile as well as a rocket.

Sur le tube lance-roquettes 6 est monté un bloc optique 1 qui comprend deux parties : un boîtier optoélectronique 11 situé à l'intérieur du tube de lancement et un boîtier optique 12 placé devant la lunette 13 du tireur et fixé sur la partie interne du boîtier optoélectronique 11.On the rocket launcher tube 6 is mounted an optical unit 1 which comprises two parts: an optoelectronic box 11 located inside the launching tube and an optical box 12 placed in front of the shooter's scope 13 and fixed on the internal part of the optoelectronic box 11.

Un calculateur 3, comportant des circuits logiques à base de microprocesseurs et des circuits analogiques d'interface, permet de gérer le bloc optique 1, ainsi qu'un pupitre de commande 21 et un écran vidéo 22 qui constituent un poste d'instructeur 2. De ce poste, l'instructeur organise les exercices de tir et apprécie les résultats.A computer 3, comprising logic circuits based on microprocessors and analog interface circuits, makes it possible to manage the optical unit 1, as well as a control desk 21 and a video screen 22 which constitute an instructor station 2. From this position, the instructor organizes the shooting exercises and assesses the results.

Une batterie 4 fournit le courant d'alimentation sous une tension de 27 V. Elle comporte également des circuits électroniques qui permettent de la recharger à partir du réseau, ou d'alimenter directement le simulateur à partir du réseau. Un anémomètre 7, sensible à la force et à l'orientation du vent, et situé en avant du poste de tir dans la direction de la cible. permet de prendre en compte le vent transversal dans les calculs. Enfin des câbles de raccordement 5 assurent les liaisons fonctionnelles nécessaires entre le calculateur et les différents éléments.A battery 4 supplies the supply current at a voltage of 27 V. It also includes electronic circuits which make it possible to recharge it from the network, or to supply the simulator directly from the network. An anemometer 7, sensitive to the force and orientation of the wind, and located in front of the firing station in the direction of the target. allows the cross wind to be taken into account in the calculations. Finally, connection cables 5 provide the necessary functional links between the computer and the various elements.

La figure 2 représente une vue de dessus du bloc optique 1 intégré dans le tube 6. Ce bloc optique 1 comprend différents éléments qui ont pour fonction d'une part de présenter à l'observation du tireur, dans la lunette 13, un champ de vision comprenant le champ de tir, avec ou sans cible réelle, un réticule matérialisant l'axe de visée, et éventuellement une cible fictive, d'autre part de reprendre une image de ce champ de vision pour la transmettre au poste d'instructeur.FIG. 2 represents a top view of the optical unit 1 integrated in the tube 6. This optical unit 1 comprises various elements which have the function on the one hand of presenting to the shooter's observation, in the scope 13, a field of vision comprising the shooting range, with or without real target, a reticle materializing the line of sight, and possibly a fictitious target, on the other hand to take an image of this field of vision to transmit it to the instructor station.

Dans le boîtier optoélectronique 11, un dispositif de génération d'image synthétique 111 permet de produire des images de cible fictive sous la commande du calculateur 3. Ce générateur d'image, dans le cas particulier considéré ici, est du type à tube cathodique flying-spot tel que décrit dans la demande de brevet FR-A-2 507 764 déposée au nom de la demanderesse le 12 juin 1981. Les images de cible successives produites sur le tube sont transmises vers le bloc optique 12 et la lunette 13 par un prisme à surface semi- réfléchissante 122 et une lame semi-réfléchissante 121 du boîtier optique 12, l'un comme l'autre orientés à 45 degrés du trajet optique.In the optoelectronic package 11, a synthetic image generation device 111 makes it possible to produce fictitious target images under the control of the computer 3. This image generator, in the particular case considered here, is of the flying cathode-ray tube type -spot as described in patent application FR-A-2 507 764 filed on behalf of the applicant on June 12, 1981. The successive target images produced on the tube are transmitted to the optical unit 12 and the telescope 13 by a prism with semi-reflecting surface 122 and a semi-reflecting plate 121 of the optical unit 12, both oriented at 45 degrees from the optical path.

Une caméra vidéo 112 est disposée dans le boîtier optoélectronique 11, à côté du générateur d'image 111, de manière à effectuer la prise de vue du champ optique visible de la lunette du tireur 13, qui lui est renvoyée par la lame semi- réfléchissante 121 et un prisme à surface semi- réfléchissante 116. L'image est retransmise par l'appareillage électronique pour être reproduite sur l'écran vidéo 22 du poste d'instructeur 2.A video camera 112 is disposed in the optoelectronic box 11, next to the image generator 111, so as to take the picture of the visible optical field of the shooter's scope 13, which is returned to it by the semi-reflecting blade 121 and a prism with a semi-reflecting surface 116. The image is retransmitted by the electronic equipment to be reproduced on the video screen 22 of the instructor station 2.

Le bloc optoélectronique contient en outre un gyroscope 113 qui fournit des informations au calculateur sur les mouvements qui peuvent être imprimés à l'arme pendant les opérations, de sorte que le calculateur puisse compenser ces mouvements dans les calculs. De même, un détecteur de devers 114, relié également au calculateur, permet de corriger le calcul du point d'impact en fonction du devers.The optoelectronic block also contains a gyroscope 113 which provides information to the computer on the movements which can be printed on the weapon during the operations, so that the computer can compensate for these movements in the calculations. Likewise, a slope detector 114, also connected to the computer, makes it possible to correct the calculation of the point of impact as a function of the slope.

Chaque élément du boîtier optoélectronique est en lui-même bien connu de l'homme de l'art et ne nécessite pas de description plus détaillée. Il en est d'ailleurs de même des différents organes optiques du boîtier optique 12.Each element of the optoelectronic package is in itself well known to those skilled in the art and does not require a more detailed description. It is also the same for the various optical members of the optical unit 12.

Dans ce dernier se trouve en particulier la lame semi-transparente 121 déjà mentionnée, qui est située devant l'objectif de la lunette 13 et qui permet de transmettre au tireur l'image du paysage, en lui superposant les images réfléchies provenant du généateur d'images 111. Elle permet aussi de renvoyer l'ensemble de ces images, constituant l'image globale du champ de vision du tieur, vers la caméra vidéo 112, à travers un diaphragme 125, réglable automatiquement. Deux filtres gris commutables 124 permettent d'atténuer la luminosité du paysage.In the latter is in particular the semi-transparent blade 121 already mentioned, which is located in front of the lens of the telescope 13 and which makes it possible to transmit to the shooter the image of the landscape, by superimposing on it the reflected images coming from the generator. images 111. It also makes it possible to return all of these images, constituting the overall image of the field of vision of the third party, to the video camera 112, through a diaphragm 125, which is automatically adjustable. Two switchable gray filters 124 attenuate the brightness of the landscape.

Le tireur voit en outre dans la lunette 13 un réticule lié à l'axe de visée de l'arme, qui peut, soit être gravé à l'intérieur de la lunette ou projeté dessus par des moyens optiques classiques, soit être produit par le générateur d'images 111, sous la commande du calculateur, et une cible fictive, générée par le dispositif .111 et superposée au paysage.The shooter also sees in the scope 13 a reticle linked to the aiming axis of the weapon, which can either be engraved inside the scope or projected onto it by conventional optical means, or be produced by the image generator 111, under the control of the calculator, and a fictitious target, generated by the device .111 and superimposed on the landscape.

Le bloc optique comporte par ailleurs, selon l'invention, un voile d'occultation 123, actionné par un électro-aimant à rotation 126, qui peut être amené en travers du trajet optique pour supprimer la vision du paysage dans le lunette 13 après le départ simulé de la roquette. Ce déplacement du voile 123 s'effectue sous la commande d'un ordre qui est émis du calculateur au moment où le tireur déclenche le tir en appuyant sur la gâchette de son arme. Tel qu'il est placé sur la figure 2, ce dispositif d'occultation laisse toujours subsister à la vue d'une personne regardant par la lunette, les images provenant du générateur d'images 111. De ce fait, la disposition représentée convient mieux au cas où la cible est une cible réelle, qui est alors éclipsée avec le paysage au moment de l'occultation par le voile 123. Dans une variante de réalisation, le voile est déplacé pour se trouver entre la lame 121 et la lunette 13, de sorte que les images provenant du générateur 111, en particulier celles représentant une cible fictive, sont cachées à la vue du tireur en même temps que le paysage lors de l'occultation.The optical unit also comprises, according to the invention, a concealing veil 123, actuated by a rotating electromagnet 126, which can be brought across the optical path to suppress the vision of the landscape in the telescope 13 after the simulated rocket departure. This movement of the web 123 is carried out under the command of an order which is issued from the computer at the time when the shooter triggers the firing by pressing the trigger of his weapon. As it is placed in FIG. 2, this concealment device always allows the images coming from the image generator 111 to remain visible to a person looking through the telescope. As a result, the arrangement shown is better suited if the target is a real target, which is then eclipsed with the landscape at the time of concealment by the veil 123. In an alternative embodiment, the veil is moved to be between the blade 121 and the telescope 13, so that the images from the generator 111, in particular those representing a fictitious target, are hidden from the view of the shooter at the same time as the landscape during the occultation.

On a fait apparaître en outre sur la figure 2, une bonnette 127, disposée devant le boîtier optique 12. Elle est utile dans le cas d'un entraînement en salle. En effet, alors que dans la présente description, on s'est plutôt référé à un entraînement à l'extérieur, devant un terrain de tir réel, le même dispositif peut être utilisé, dans des conditions similaires, pour un fonctionnement en salle. Le terrain de tir est alors constitué par une image de paysage projetée dans le champ de vision du tireur. Il peut s'agir par exemple d'images fixes projetées à partir de dispositives dans le cas où la cible est une cible dite fictive formée par ailleurs, ou d'images projetées à partir d'un film figurant une cible mobile se déplaçant sur un terrain fixe, le mode de fonctionnement étant alors celui d'un entraînement sur cible dite réelle.In addition, FIG. 2 shows a windscreen 127, placed in front of the optical unit 12. It is useful in the case of indoor training. Indeed, while in the present description, we have rather referred to training outside, in front of a real shooting range, the same device can be used, under similar conditions, for indoor operation. The shooting range is then constituted by a landscape image projected into the shooter's field of vision. These may for example be fixed images projected from devices in the case where the target is a so-called fictitious target formed elsewhere, or images projected from a film depicting a moving target moving on a fixed ground, the operating mode then being that of a so-called real target training.

Sur la figure 3 on voit mieux que le calculateur 3 est en relation fonctionnelle avec les organes du poste du tireur, qui apparaissent dans la partie supérieure de la figure, et ceux du poste de l'instructeur, que l'on a représentés dans la partie inférieure. Ainsi, ce calculateur reçoit des informations, principalement du dispositif de lancement ou déclenchement du tir 14, d'un dispositif de commande de la génération d'une cible fictive 15, à la disposition de l'instructeur, et d'un dispositif de pilotage d'index 16 dont l'utilité apparaîtra plus loin. Il reçoit aussi des signaux de synchronisation d'un ensemble électronique de commande vidéo 17, qui gère le fonctionnement de la caméra 112 et assure la sommation des signaux vidéo reçus de la caméra et du calculateur pour les transmettre au moniteur vidéo 18 commandant la visualisation sur l'écran du poste d'instructeur. Des organes plus accessoires dont les informations interviennent en plus dans les calculs n'ont pas été représentés.In FIG. 3, it is better to see that the computer 3 is in functional relation with the organs of the shooter's station, which appear in the upper part of the figure, and those of the instructor's station, which have been represented in the lower part. Thus, this computer receives information, mainly from the launching or triggering device of the shot 14, from a device for controlling the generation of a fictitious target 15, available to the instructor, and from a piloting device. index 16 whose usefulness will appear later. It also receives synchronization signals from an electronic video control unit 17, which manages the operation of the camera 112 and adds the video signals received from the camera and the computer to transmit them to the video monitor 18 controlling the visualization on instructor station screen. More accessory bodies whose information is also involved in the calculations have not been shown.

D'autre part, le calculateur émet des ordres, comme on l'a déjà expliqué, principalement en direction du générateur d'images 111, que l'on a représenté avec son tube cathodique 19 et l'alimentation (20) en courant à très haute tension de ce dernier, et en direction du dispositif d'occultation 23, qui comprend le voile 123 et son moteur d'entraînement 126. Il produit aussi des signaux d'incrustation vidéo, qui sont transmis à l'ensemble électronique 17'en vue de la visualisation des informations correspondantes sur l'écran 22 du poste d'instructeur. Enfin, le calculateur 3 détermine, en fonction principalement de caractéristiques préalablement enregistrées du projectile simulé, de la distance de la cible et des autres paramètres mentionnés, quel serait le point d'impact de ce pojectile dans le plan de la cible.On the other hand, the computer emits orders, as has already been explained, mainly in the direction of the image generator 111, which is shown with its cathode ray tube 19 and the current supply (20) at very high voltage of the latter, and in the direction of the concealment device 23, which comprises the web 123 and its drive motor 126. It also produces video overlay signals, which are transmitted to the electronic assembly 17 ' for viewing the corresponding information on the screen 22 of the instructor station. Finally, the computer 3 determines, mainly as a function of previously recorded characteristics of the simulated projectile, the distance from the target and the other parameters mentioned, what would be the point of impact of this pojectile in the plane of the target.

La figure 4 montre les indications qui sont visualisées sur l'écran de l'instructeur sous la commande des signaux d'incrustation. On n'y a pas représenté le paysage qui s'y ajoute, retransmis du champ de vision du tireur, avec éventuellement une cible réelle évoluant sur le terrain, jusqu'au moment de l'occultation. On a par contre fait figurer la cible fictive 43 qui y apparaît, dans le cas d'un fonctionnement avec cible fictive, retransmise par la caméra 112 du générateur d'images 11. Les signaux d'incrustation contiennent les informations nécessaires à la visualisation d'un réticule 41, identique à celui qui est présenté à la vue du tireur et lié comme lui à l'axe de visée 45, d'un index 44 que l'instructeur détermine, sous la forme d'un rectangle variable en position et en dimensions, dans le cas d'un fonctionnement avec cible réelle, et d'une croix d'impact 42 caractérisant la position du point d'impact déterminé par le calculateur.FIG. 4 shows the indications which are displayed on the instructor's screen under the control of the overlay signals. We did not represent the landscape which is added to it, retransmitted from the field of vision of the shooter, with possibly a real target evolving on the ground, until the moment of occultation. On the other hand, the fictitious target 43 which appears there, in the case of an operation with a fictitious target, retransmitted by the camera 112 of the image generator 11. The overlay signals contain the information necessary for viewing 'a reticle 41, identical to that which is presented to the viewer of the shooter and linked like him to the line of sight 45, with an index 44 that the instructor determines, in the form of a variable rectangle in position and in dimensions, in the case of operation with an actual target, and an impact cross 42 characterizing the position of the point of impact determined by the computer.

On reviendra maintenant à la figure 1 pour décrire le pupitre de commande 21 du poste d'instructeur 2 et décrire comment l'instructeur sélectionne les différentes conditions de fonctionnement et assure les différentes commandes, en particulier par les dispositifs 15 et 16 de la figure 3 et en introduisant dans le calculateur 3 les paramètres nécessaires à la simulation.We will now return to FIG. 1 to describe the control desk 21 of the instructor station 2 and to describe how the instructor selects the different operating conditions and provides the different commands, in particular by the devices 15 and 16 of FIG. 3 and by introducing into the computer 3 the parameters necessary for the simulation.

Une première partie du pupitre 21 permet à l'instructeur, après la mise sous tension (commandée sur le calculateur), de choisir entre trois fonctions, suivant qu'il actionne une touche « initialisation 211, une touche « cible fictive 212, une touche « cible réelle » 213. En général l'instructeur choisit d'abord la touche « initialisation » 211, car il lui faut s'assurer que l'harmonisation des origines est correcte. En effet, les origines ou axes de référence pour la génération de cible fictive et l'incrustation vidéo du réticule de visée doivent être confondues avec l'origine du réticule de la lunette du tireur. Pour ce faire l'instructeur utilise la zone 219 du pupitre de commande qui lui permet, en agissant sur les boutons de potentiomètres groupés par trois, d'abord d'aligner sur le réticule de la lunette du tireur une croix de référence générée par le simulateur, centrée sur un axe de référence, ensuite d'aligner sur la croix le réticule incrusté sur l'écran. Les trois potentiomètres de chaque groupe permettent de déplacer l'image correspondante respectivement en X, en Y et en rotation (fig. 4).A first part of the desk 21 allows the instructor, after the power up (controlled on the computer), to choose between three functions, depending on whether he presses a key "initialization 211, a key" dummy target 212, a key "Real target" 213 . In general, the instructor first chooses the "initialization" key 211, because he must ensure that the harmonization of the origins is correct. Indeed, the origins or axes of reference for the generation of a fictitious target and the video overlay of the aiming reticle must be confused with the origin of the reticle of the shooter's scope. To do this, the instructor uses zone 219 of the control console which allows him, by acting on the potentiometer buttons grouped by three, to first align with the reticle of the telescope of the shooter a reference cross generated by the simulator, centered on a reference axis, then align the crosshairs on the screen with the cross. The three potentiometers of each group allow to move the corresponding image respectively in X, in Y and in rotation (fig. 4).

Pour un mode de fonctionnement en cible fictive, l'instructeur dispose de la partie 218 du pupitre, qui lui permet d'enregistrer les paramètres de plusieurs cibles fictives avant les séances d'instruction, à savoir par exemple, pour chaque cible : un numéro repère, la.distance d de la cible à son apparition, sa vitesse, son orientation dans l'espace par rapport aux directions horizontale et verticale, sa position en X et en Y par rapport au centre du champ (toujours au moment de son apparition), la pente du terrain sur lequel elle évolue, sa luminosité. Il lui est possible également de modifier la trajectoire linéaire enregistrée d'une cible donnée, en cours d'exercice, par action en temps réel sur un manche de pilotage 215 qui permet de modifier l'orientation de la cible et de faire varier sa vitesse.For a fictitious target mode of operation, the instructor has part 218 of the desk, which allows him to record the parameters of several fictitious targets before the instruction sessions, namely for example, for each target: a number landmark, the distance d of the target at its appearance, its speed, its orientation in space relative to the horizontal and vertical directions, its position in X and in Y compared to the center of the field (always at the time of its appearance ), the slope of the terrain on which it operates, its brightness. It is also possible for him to modify the recorded linear trajectory of a given target, during exercise, by action in real time on a control stick 215 which makes it possible to modify the orientation of the target and to vary its speed. .

La partie 214 du pupitre s'utilise en conjonction avec le manche de pilotage 215 lorsque l'instructeur a choisi le mode de fonctionnement sur cible réelle. Dans ce mode de fonctionnement le calculateur génère sur l'écran vidéo l'index rectangulaire 44 et l'instructeur amène cet index en superposition sur la cible (qu'il observe sur le paysage retransmis par la caméra) au moyen du manche de pilotage 215. En même temps, en agissant sur des potentiomètres 216 et 217 en fonction de la hauteur de la cible et de sa largeur, il règle la grandeur de l'index pour que celui-ci corresponde aux dimensions de la cible. En commandant cet index l'instructeur poursuit la cible jusqu'au départ du coup, ce qui permet au calculateur de déterminer par l'évolution de la grandeur, de la position et de la vitesse de l'index, la distance, la position, la vitesse et le sens de déplacement de la cible au moment du déclenchement du tir.Part 214 of the desk is used in conjunction with the control stick 215 when the instructor has chosen the operating mode on real target. In this operating mode, the computer generates the rectangular index 44 on the video screen and the instructor brings this index superimposed on the target (which he observes on the landscape retransmitted by the camera) by means of the control stick 215 At the same time, by acting on potentiometers 216 and 217 according to the height of the target and its width, it adjusts the size of the index so that it corresponds to the dimensions of the target. By ordering this index, the instructor pursues the target until the start of the shot, which allows the computer to determine by the evolution of the magnitude, the position and the speed of the index, the distance, the position, the target's speed and direction of movement when the shot was fired.

Les circuits électroniques associés aux différents organes du simulateur, en particulier ceux du pupitre de commande, sont classiques et à la portée de l'homme de l'art. Ils ne feront donc pas d'objet d'une description plus approfondie.The electronic circuits associated with the various organs of the simulator, in particular those of the control console, are conventional and within the reach of those skilled in the art. They will therefore not be the subject of a more detailed description.

Le fonctionnement du simulateur est illustré, dans le cas d'une simulation sur terrain réel avec cible fictive, par les dessins des figures 5a, 5b, 5c, qui montrent dans des étapes successives, à gauche ce que voit le tireur dans la lunette, à droite ce qui apparaît sur l'écran de l'instructeur.The operation of the simulator is illustrated, in the case of a simulation on real ground with a fictitious target, by the drawings of FIGS. 5a, 5b, 5c, which show in successive stages, on the left, what the shooter sees in the scope, on the right what appears on the instructor's screen.

Tout d'abord l'instructeur indique au tireur la position d'apparition de la cible (par exemple : char en lisière du bosquet à droite). Le tireur prépare son arme et la dirige vers l'endroit désigné. L'instructeur, lorsqu'il estime que le tireur vise la zone indiquée, décide du départ de la cible, en provoquant la génération d'une cible fictive dont il a préalablement enregistré les paramètres (fig.5a). Durant la poursuite de la cible par le tireur, il peut modifier l'évolution de celle-ci en agissant sur le manche de pilotage 215 et ainsi compliquer la tâche du tireur pour l'habituer à se méfier de la facilité apparente de poursuite.First of all the instructor indicates to the shooter the position of appearance of the target (for example: tank at the edge of the grove on the right). The shooter prepares his weapon and directs it to the designated location. The instructor, when he considers that the shooter is targeting the indicated area, decides on the departure of the target, by causing the generation of a fictitious target whose parameters he has previously recorded (fig.5a). During the pursuit of the target by the shooter, he can modify its evolution by acting on the control stick 215 and thus complicate the task of the shooter to accustom him to being wary of the apparent ease of pursuit.

Pendant que le tireur pointe son arme (fig. 5b), l'instructeur apprécie son travail au moyen du réticule de la lunette reproduit sur le moniteur vidéo. Quand il estime sa visée correcte, le tireur commande la mise à feu de la roquette fictive. Le déclenchement du tir provoque instantanément le déplacement du voile d'occultation du bloc optique, qui obstrue alors la vision du paysage pour le tireur et l'instructeur, et même celle de la cible fictive pour le tireur dans le cas représenté (fig. 5c). Le tireur pose alors son arme et s'éloigne, puis rejoint l'instructeur devant l'écran vidéo pour apprécier le résultat du tir. Ils peuvent y voir le réticule de visée incrusté 41, la cible fictive 43, dont la position est figée à l'instant de déclenchement du tir augmenté du temps de trajet simulé de la roquette, et la croix d'impact 42 figurant le point d'impact.While the shooter points his weapon (fig. 5b), the instructor appreciates his work by means of the telescopic reticle reproduced on the video monitor. When he considers his aim correct, the shooter orders the firing of the fictitious rocket. The triggering of the shot instantly causes the movement of the concealment veil of the optical unit, which then obstructs the vision of the landscape for the shooter and the instructor, and even that of the fictitious target for the shooter in the case shown (fig. 5c ). The shooter then puts down his weapon and moves away, then joins the instructor in front of the video screen to assess the result of the shot. They can see there the inlaid aiming reticle 41, the fictitious target 43, whose position is frozen at the instant of launching of the firing increased by the simulated travel time of the rocket, and the impact cross 42 representing the point d 'impact.

Dans le cas d'une simulation de tir sur cible réelle, le fonctionnement est sensiblement le même sauf que la cible disparaîtra de l'écran de l'instructeur avec le paysage. C'est pourquoi dans ce cas, le calculateur génère l'index 44 qui va permettre à l'instructeur de poursuivre la cible réelle, au moyen du manche de pilotage, jusqu'à l'instant où le déclenchement du tir provoque l'occultation, et d'indiquer ainsi au calculateur la position de la cible et les paramètres de son évolution. Par la suite le calculateur considère la vitesse de la cible comme constante durant le trajet du projectile fictif. Pour juger le résultat du tir, l'instructeur compare la position de l'index 44 avec la position de la croix 42 symbolisant l'impact.In the case of a real target shooting simulation, the operation is essentially the same except that the target will disappear from the instructor's screen with the landscape. This is why in this case, the computer generates the index 44 which will allow the instructor to pursue the real target, by means of the piloting stick, until the moment when the triggering of the shot causes the occultation. , and thus indicate to the computer the position of the target and the parameters of its evolution. Subsequently, the computer considers the speed of the target as constant during the path of the fictitious projectile. To judge the result of the shot, the instructor compares the position of the index finger 44 with the position of the cross 42 symbolizing the impact.
