Abstract

The visualisation method involves using an object designation system (1). The system determines, relatively to a reference position, an azimuth and a site angles of the object (31) direction. The azimuth angle is carried over on a two-dimensional display (6) w.r.t a corresponding direction from the reference position representation. The site angle is carried over as an object representation according to the azimuth angle direction and at a distance from the reference position which is function of the site angle. The designation system may comprise a passive IR detector (2) with a scanning device (3). This is arranged to determine the direction and elevation of the line of sight to the object relative to a reference direction, leading to the information of a two dimensional view on a screen. The speed vector of the object is also estimated, and a predicted line of travel is determined. use/ <IMAGE>

Description

La désignation d'objectif permet de fournir à un système d'arme des informations permettant de pointer l'arme dans la direction d'un objectif, ou cible. Un système de désignation d'objectif comporte des moyens de détection pour surveiller un volume d'espace déterminé et pour détecter la direction de tout rayonnement provenant d'un objectif, afin de fournir au système d'arme l'information de direction relative de l'objectif.Objective designation provides a weapon system with information allowing to point the weapon in the direction of a target, or target. A target designation system includes means for detection to monitor a determined volume of space and to detect the direction of any radiation from a target, in order to provide to the weapon system the relative direction information of the objective.

On connaít deux types de détecteurs.There are two types of detectors.

Le premier type de détecteur est associé à un émetteur pour constituer un ensemble de détection actif, comme un radar ou un sonar. L'objectif est "illuminé" par l'émetteur et le détecteur reçoit une onde réfléchie.The first type of detector is associated with a transmitter to constitute an active detection set, such as a radar or sonar. The objective is "illuminated" by the transmitter and the detector receives a reflected wave.

Le temps de parcours aller et retour de l'onde permet, en plus, de calculer la distance de l'objectif au détecteur. Disposant de la direction et de la distance, le détecteur peut ainsi fournir, à des calculateurs du système d'arme, la position de l'objectif dans tout système de coordonnées absolues, directement interprétable par les calculateurs. De ce fait, le détecteur et le système d'arme peuvent être éloignés l'un de l'autre, ce qui permet de mettre à l'abri les calculateurs en les plaçant dans des locaux protégés ou camouflés, alors qu'existe le risque que l'émetteur, détectable, et associé au détecteur, ne soit détruit par un missile adverse.The round trip time of the wave allows, in addition, calculate the distance from the lens to the detector. With management and distance, the detector can thus supply calculators with weapon system, the position of the objective in any system of absolute coordinates, directly interpretable by computers. Therefore, the detector and the weapon system can be moved apart on the other, which makes it possible to shelter the computers by placing them in protected or camouflaged premises, while there is the risk that the transmitter, detectable, and associated with the detector, is not destroyed by a opposing missile.

Le second type de détecteur est passif et comporte un capteur, en général un capteur infrarouge. Sa discrétion le met mieux à l'abri des missiles adverses, mais il subsiste toujours un risque de destruction s'il est lui-même détecté ou s'il est au voisinage d'une cible potentielle pour un missile adverse. The second type of detector is passive and includes a sensor, in generally an infrared sensor. His discretion puts him better away from enemy missiles, but there is still a risk of destruction if is itself detected or if it is in the vicinity of a potential target for an enemy missile.

Cependant, comme un détecteur passif ne peut pas déterminer la distance de l'objectif par mesure d'un temps de trajet d'une onde émise et réfléchie sur l'objectif, il était estimé que le système d'arme, toujours dans le cadre de l'application des détecteurs passifs, ne pouvait être qu'au voisinage du détecteur et avoir une ligne de visée harmonisée avec celle du détecteur.However, as a passive detector cannot determine the distance from the objective by measuring a travel time of an emitted wave and reflected on the objective, it was felt that the weapon system, always as part of the application of passive detectors, could not be than in the vicinity of the detector and have a harmonized line of sight with that of the detector.

Ainsi, ou bien le détecteur était actif avec le risque qu'il soit détruit, ou bien le détecteur était passif, avec le risque que non seulement le détecteur mais également le système d'arme soient détruits. Le document FR-A-2 415 285 décrit de tels détecteurs.Thus, either the detector was active with the risk of it being destroyed, or well the detector was passive, with the risk that not only the detector but also the weapon system are destroyed. Document FR-A-2 415 285 describes such detectors.

La présente invention vise, dans l'application d'un détecteur passif, à supprimer ce risque.The present invention aims, in the application of a passive detector, to remove this risk.

A cet effet, l'invention concerne un procédé pour exploiter un système d'arme associé à un système de désignation d'objectif détecteur passif, caractérisé par le fait qu'on déporte le système d'arme par rapport au système de désignation d'objectif, on détermine la position relative des deux systèmes, à partir de cette dernière et d'une direction d'objectif fournie par le système de désignation d'objectif on détermine un ensemble de positions possibles de l'objectif dans un repère lié au système d'arme ainsi que les directions de tir passant par ces positions possibles et le système d'arme, et le système d'arme balaie ces directions de tir.To this end, the invention relates to a method for operating a system weapon associated with a passive detector objective designation system, characterized by the fact that the weapon system is deported from the objective designation system, the relative position of the two systems, from the latter and from a lens direction provided by the system objective designation a set of positions is determined possible of the objective in a reference linked to the weapon system as well as the directions of fire passing through these possible positions and the system weapon, and the weapon system scans these fire directions.

Ainsi, même si la position de l'objectif n'est pas entièrement définie, le système d'arme peut l'acquérir lors du balayage, par exemple grâce à des auto-directeurs à champ étroit de missiles de défense. On comprendra que le balayage peut n'être qu'un balayage électronique d'un système de visée.So even if the lens position is not fully defined, the weapon system can acquire it during scanning, for example through self-directing narrow-field defense missiles. We will understand that the scan may be just an electronic scan a sighting system.

L'invention concerne aussi un ensemble, pour la mise en oeuvre du procédé de l'invention, d'un système d'arme et d'un système associé de désignation d'objectif qui comporte un détecteur passif et des moyens de détermination de direction d'objectif, caractérisé par le fait que le système d'arme est déporté par rapport au système de désignation d'objectif et y est relié et qu'il est prévu des moyens de détermination de la position relative des deux systèmes et des moyens de détermination de direction de tir commandés par le détecteur et agencés pour commander le tir en fonction de la direction d'objectif et de la position relative des deux systèmes.The invention also relates to an assembly, for implementing the method of the invention, a weapon system and an associated system of objective designation which comprises a passive detector and means for determination of objective direction, characterized in that the weapon system is offset from the designation system objective and is linked to it and that means are provided for determining the relative position of the two systems and the means of determination direction of fire controlled by the detector and arranged for control the shooting according to the direction of the objective and the position relative of the two systems.

L'invention sera mieux comprise à l'aide de la description suivante de la forme de réalisation préférée de l'ensemble d'un système de désignation d'objectif et d'un système d'arme mettant en oeuvre le procédé de l'invention, représentés schématiquement sur la figure unique du dessin annexé.The invention will be better understood using the following description of the preferred embodiment of the entire designation system objective and a weapon system implementing the method of the invention, shown schematically in the single figure of the drawing Annex.

Un système 1 de désignation d'objectif est associé à un système d'arme 11, ici de défense anti-aérienne, disposant de missiles sol-air et déporté par rapport au système 1 de désignation d'objectif. Les deux systèmes 1, 11 sont reliés par une liaison de données 20. Les positions géographiques des deux systèmes 1, 11 sont connues et leur position relative est mémorisée dans une mémoire 13 appartenant à un calculateur 12 relié à la liaison 20 et situé, dans cet exemple, dans le système d'arme 11.A target designation system 1 is associated with a weapon system 11, here of anti-aircraft defense, having surface-to-air missiles and deported compared to the objective designation system 1. The two systems 1, 11 are connected by a data link 20. The positions of the two systems 1, 11 are known and their position relative is stored in a memory 13 belonging to a computer 12 connected to link 20 and located, in this example, in the weapon system 11.

Le système 1 de désignation d'objectif comporte un détecteur passif 2, ici infrarouge, qui est dans cet exemple entraíné par un dispositif de balayage 3 autour d'un axe vertical pour surveiller, dans toutes les directions d'azimut, un volume d'espace entourant le système 1 de désignation d'objectif. Ce volume est ici limité à une plage d'angles de site de six degrés. Le signal de détection en sortie du détecteur 2, associé à un signal représentatif de la position angulaire correspondante du dispositif de balayage 3, sont fournis à un calculateur 4 qui en détermine la direction 10 d'un objectif détecté 31, ici un avion, exprimée en angle de site et angle d'azimut, par rapport à un repère lié au système 1 de désignation d'objectif.The objective designation system 1 comprises a passive detector 2, here infrared, which is in this example driven by a device for scan 3 around a vertical axis to monitor, in all azimuth directions, a volume of space surrounding the system 1 of objective designation. This volume is here limited to a range of angles of six degree site. The detection signal at the output of detector 2, associated with a signal representative of the corresponding angular position of the scanning device 3, are supplied to a computer 4 which determines the direction 10 of a detected objective 31, here an airplane, expressed in elevation angle and azimuth angle, relative to a reference linked to the objective designation system 1.

En l'absence d'estimation de distance entre le système 1 de désignation d'objectif et l'objectif 31, la droite 10 de direction de l'objectif 31 correspond, dans la limite de la portée 32 du détecteur 2, à un ensemble de positions possibles de l'objectif 31. In the absence of an estimate of the distance between the designation system 1 of objective and objective 31, the right direction 10 of objective 31 corresponds, within the limit of the range 32 of the detector 2, to a set of possible positions of objective 31.

Un signal numérique 5 de données représentatives de la direction 10 de l'objectif 31 est émis sur la liaison 20 par le calculateur 4 à destination du calculateur 12 du système d'arme 11. Le calculateur 12 en détermine alors par triangulation, au moyen de la position relative mémorisée dans la mémoire 13, un ensemble de positions possibles de l'objectif 31, (segment 33, entre le détecteur 2 et le point 32), dans un repère lié au système d'arme 11 et en calcule des directions de tir correspondantes passant par ces positions possibles 33 et le système d'arme 11, et le système d'arme 11 balaye ces directions de tir (30, 30A) sous la commande du calculateur 12. Ce dernier aurait aussi pu être disposé dans le système 1 de désignation d'objectif et commander le balayage à travers la liaison 20.A digital signal 5 of data representative of the direction 10 of the objective 31 is emitted on the link 20 by the computer 4 at destination of the computer 12 of the weapon system 11. The computer 12 determines then by triangulation, by means of the relative position memorized in memory 13, a set of possible positions of objective 31, (segment 33, between detector 2 and point 32), in a reference linked to the weapon system 11 and calculates corresponding firing directions going through these possible positions 33 and the weapon system 11, and the weapon system 11 scans these firing directions (30, 30A) under the control of computer 12. The latter could also have been arranged in the lens designation system 1 and control scanning at through link 20.

Pour simplifier le balayage ci-dessus, le système d'arme 11 procède au balayage dans un plan contenant la direction d'objectif 10.To simplify the above scanning, the weapon system 11 proceeds to scanning in a plane containing the direction of objective 10.

Dans cet exemple, afin de limiter l'ampleur du balayage du système d'arme 11, on restreint l'ensemble des positions possibles 33 de l'objectif 31 en estimant la distance D, du détecteur 2 à l'objectif 31, d'après l'amplitude mesurée du signal de détection du détecteur 2 et de sa variation au cours du temps. Le spectre de ce signal ainsi que les conditions de propagation atmosphérique permettent aussi d'estimer la distance de l'objectif 31 au système 1 de désignation d'objectif. De même, la détermination, au moyen du détecteur 2, de l'angle de présentation de l'avion 31 et de son type permet, au moyen de tables de correspondance, d'estimer l'énergie rayonnée vers le détecteur 2 et, par comparaison avec celle reçue, de déterminer approximativement la distance D recherchée. Cette estimation de distance D est ici effectuée par le calculateur 4 et transmise au calculateur 12. Ce dernier aurait pu effectuer cette estimation lui-même, à partir du signal du détecteur 2, émis sous une forme appropriée sur la liaison 20.In this example, to limit the amount of system scanning weapon 11, we restrict all the possible positions 33 of objective 31 by estimating the distance D, from detector 2 to objective 31, based on the measured amplitude of the detector 2 detection signal and its variation over time. The spectrum of this signal and the atmospheric propagation conditions also make it possible to estimate the distance from objective 31 to objective designation system 1. Of even, the determination, by means of detector 2, of the angle of presentation of the airplane 31 and its type allows, by means of tables correspondence, to estimate the energy radiated towards detector 2 and, by comparison with that received, to determine approximately the distance D sought. This estimation of distance D is carried out here by the computer 4 and transmitted to the computer 12. The latter could have make this estimate itself, from the signal from detector 2, issued in an appropriate form on link 20.

Dans le cas où le système d'arme 11 dispose, comme ici, de missiles, il peut être prévu qu'ils soient lancés selon l'une des directions de tir et qu'un auto-directeur de missile effectue le balayage pour acquérir l'image de l'objectif. Le tir peut aussi être effectué après acquisition de l'objectif 31 par l'auto-directeur.In the case where the weapon system 11 has, as here, missiles, it can be expected to be launched in one of the firing directions and that a missile self-director scans to acquire the image of the lens. The shooting can also be carried out after acquisition of goal 31 by the self-director.

Dans le cas où la distance D est estimée ou lorsque l'auto-directeur "accroche" l'objectif 31, le triangle formé par le détecteur 2, le système d'arme 11 et l'objectif 31 est alors défini et le système d'arme 11 peut déterminer sa distance à l'objectif 31 afin de la comparer à sa portée de tir et fournir une indication correspondante à un exploitant du système.In case the distance D is estimated or when the self-steering "hooks" the objective 31, the triangle formed by the detector 2, the system weapon 11 and objective 31 is then defined and weapon system 11 can determine its distance to objective 31 in order to compare it with its range of fire and provide a corresponding indication to a system operator.

Dans le cas où le système d'arme ne comporte aucun détecteur, il convient alors qu'il tire des munitions dans toutes les directions possibles de tir indiquées ci-dessus.If the weapon system has no detector, it suitable as it fires ammunition in all directions firing possibilities indicated above.

Pour faciliter l'exploitation de l'ensemble des systèmes 1, 11, et en particulier s'il est prévu plusieurs systèmes d'arme entourant à distance le système 1 de désignation d'objectif, ce dernier comporte une console 6 de visualisation associée à un calculateur 7 recevant, du calculateur 4, le signal numérique 5 d'angle de site et d'azimut de l'objectif 31. Le calculateur 7 convertit le signal numérique 5 en un signal analogique vidéo représentant symboliquement l'objectif 31. Il peut être prévu que cette représentation symbolique dépende des valeurs des angles d'azimut et de site. Le signal vidéo est appliqué à un circuit 7V de commande vidéo pour être inséré dans un signal vidéo balayant tout un écran 8 de la console 6. Le calculateur 7 fournit aussi, au circuit 7V, des commandes de positionnement de l'image 41 de l'objectif 31 sur l'écran 8, qui sont fonction des valeurs 5 des angles d'azimut et de site.To facilitate the operation of all systems 1, 11, and especially if several weapon systems surrounding at a distance are provided the objective designation system 1, the latter comprises a console 6 of display associated with a computer 7 receiving, from the computer 4, the digital signal 5 of the site angle and azimuth of the objective 31. The computer 7 converts digital signal 5 to analog signal video symbolically representing objective 31. It can be expected that this symbolic representation depends on the values of the angles azimuth and site. The video signal is applied to a 7V circuit of video command to be inserted into a video signal scanning a whole screen 8 of the console 6. The computer 7 also supplies circuit 7V with controls for positioning the image 41 of the lens 31 on the screen 8, which are a function of the values 5 of the azimuth and elevation angles.

Dans cet exemple, le système 1 de désignation d'objectif est représenté au point central de l'écran 8 et une couronne 9 centrée sur ce point est prévue pour recevoir la représentation symbolique 41 de l'objectif 31. Un circuit déflecteur du circuit 7V est commandé à partir des commandes de positionnement du calculateur 7, c'est-à-dire en fonction des angles d'azimut et de site, afin de dévier le faisceau de balayage de l'écran 8 de telle manière que la représentation symbolique 41 soit portée, par rapport au centre de l'écran 8, dans la direction d'azimut détectée et que cette représentation symbolique 41 soit plus ou moins proche du bord interne de la couronne 9 selon que l'angle de site détecté est plus ou moins proche de la valeur inférieure de sa plage de détection.In this example, the objective designation system 1 is shown at the central point of screen 8 and a crown 9 centered on this point is planned to receive the symbolic representation 41 of objective 31. A deflector circuit of circuit 7V is controlled from the commands of positioning of the computer 7, that is to say as a function of the angles azimuth and site, to deflect the scanning beam from the screen 8 in such a way that the symbolic representation 41 is carried, by relative to the center of screen 8, in the direction of azimuth detected and that this symbolic representation 41 is more or less close to the edge internal of crown 9 depending on whether the angle of elevation detected is more or less close to the lower value of its detection range.

Les objectifs dont la distance au système 1 de désignation d'objectif est connue approximativement sont aussi repérés en coordonnées polaires (distance, azimut) dans le cercle entouré par la couronne 9, sur lequel sont reportées, autour de la position 40 du système 1 de désignation d'objectif, les positions de plusieurs systèmes d'arme, ici quatre, la zone couverte 44-47 par chacun de ceux-ci, ainsi que les seuls points caractéristiques du paysage.Objectives whose distance to objective designation system 1 is known approximately are also identified in polar coordinates (distance, azimuth) in the circle surrounded by the crown 9, on which are reported, around position 40 of the designation system 1 objective, the positions of several weapon systems, here four, the area covered 44-47 by each of these, as well as the only points landscape features.

Comme le système de désignation d'objectif peut déterminer, par des mesures successives, une vitesse et une accélération de l'objectif 31, l'exploitant du système peut choisir d'activer le missile de défense le mieux placé pour intercepter l'objectif 31. La trajectoire estimée 42 suivie par celui-ci et son vecteur vitesse estimé 43 sont aussi représentés associés à son image 41.As the objective designation system can determine, by successive measurements, a speed and an acceleration of the objective 31, the system operator can choose to activate the defense missile on better placed to intercept objective 31. The estimated trajectory 42 followed by this one and its estimated velocity vector 43 are also represented associated with its image 41.
