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>

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 information to a weapon system to point the weapon in the direction of an objective, or target.

'goal.

L'invention concerne un procédé de visualisation de cette direction et un appareil pour la mise en oeuvre du procédé.The invention relates to a method for displaying this direction and to an apparatus for implementing the method.

Plus précisément, l'invention concerne un procédé de visualisation, sur un moyen de visualisation à deux dimensions, de la direction d'observation d'un objet d'une scène observée par un système de désignation d'objectif qui en détermine, par rapport à une position de référence, un angle d'azimut et un angle de site, procédé dans lequel on reporte sur le moyen de visualisation l'angle d'azimut selon une direction correspondante à partir d'une représentation de la position de référence, caractérisé par le fait qu'on reporte l'angle de site sous la forme d'une représentation de l'objet selon la direction de l'angle d'azimut et à une distance, depuis la représentation de la position de référence, fonction de l'angle de site.More specifically, the invention relates to a method of visualizing, on a two-dimensional visualization means, the direction of observation of an object of a scene observed by a system of designation of objective which determines, with respect to to a reference position, an azimuth angle and a site angle, process in which the azimuth angle is transferred to the display means in a corresponding direction from a representation of the reference position, characterized by the fact that the elevation angle is reported in the form of a representation of the object in the direction of the azimuth angle and at a distance, from the representation of the reference position, a function of l 'elevation angle.

L'invention concerne aussi un appareil de visualisation pour la mise en oeuvre du procédé de l'invention, comportant des moyens de visualisation agencés pour reporter, à partir d'une représentation d'une position de référence, un angle d'azimut d'un objet observé, caractérisé par le fait qu'il comporte des moyens de calcul agencés pour déterminer, en fonction d'une valeur d'angle de site de l'objet, une distance entre une représentation de l'objet et la représentation de la position de référence et pour commander en conséquence les moyens de visualisation.The invention also relates to a display device for implementing the method of the invention, comprising display means arranged to report, from a representation of a reference position, an azimuth angle of an observed object, characterized in that it comprises calculation means arranged to determine, as a function of a value of the site angle of the object, a distance between a representation of the object and the representation of the reference position and to control the display means accordingly.

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 assembly of a target designation system and of a weapon system implementing the method of the invention , shown schematically in the single figure of the accompanying drawing.

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 an anti-aircraft defense system, having surface-to-air missiles and remote from the target designation system 1. The two systems 1, 11 are connected by a data link 20. The geographic positions of the two systems 1, 11 are known and their relative position is memorized in a memory 13 belonging to a computer 12 connected to the link 20 and located, in this example, in weapon system 11.

Le système 1 de désignation d'objectif comporte un détecteur passif 2, ici infrarouge, qui est dans cet exemple entraîné 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 in this example is driven by a scanning device 3 around a vertical axis to monitor, in all directions of azimuth, a volume of space surrounding the lens designation system 1. This volume is here limited to a range of elevation angles of six degrees. The detection signal at the output of the 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 aircraft, 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 objective designation system 1 and the objective 31, the straight line 10 of the objective direction 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 transmitted on the link 20 by the computer 4 to the computer 12 of the weapon system 11. The computer 12 then determines by triangulation, by means of the relative position memorized in the memory 13, a set of possible positions of the objective 31, (segment 33, between the detector 2 and the point 32), in a coordinate system linked to the weapon system 11 and calculates corresponding firing directions passing 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 the computer 12. The latter could also have been arranged in the system 1 for designation of objective and control the scanning through the 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 objective direction 10.

Dans cet exemple, afin de imiter 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, in order to imitate the extent of the scanning of the weapon system 11, all the possible positions 33 of the objective 31 are restricted by estimating the distance D, from the detector 2 to the objective 31, of after the measured amplitude of the detector 2 detection signal and its variation over time. The spectrum of this signal as well as the atmospheric propagation conditions also make it possible to estimate the distance from the objective 31 to the objective designation system 1. Similarly, the determination, by means of the detector 2, of the angle of presentation of the airplane 31 and of its type makes it possible, by means of correspondence tables, to estimate the energy radiated towards the detector 2 and, by comparison with that received, to determine approximately the distance D sought. This estimate of distance D is here carried out by the computer 4 and transmitted to the computer 12. The latter could have made this estimate itself, from the signal from the detector 2, transmitted in an appropriate form on the 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 provided that they are launched in one of the firing directions and that a missile self-director carries out the scanning to acquire the image of the lens. The shooting can also be carried out after acquisition of the objective 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 the case where the distance D is estimated or when the auto-director "catches" the objective 31, the triangle formed by the detector 2, the system weapon 11 and objective 31 is then defined and the weapon system 11 can determine its distance from objective 31 in order to compare it with its firing range and provide a corresponding indication to an operator of the system.

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.In the event that the weapon system does not have any detector, it should then fire ammunition in all possible directions of fire 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 the systems 1, 11, and in particular if several weapon systems are provided surrounding the objective designation system 1 remotely, the latter comprises a display console 6 associated with a computer 7 receiving, from the computer 4, the digital signal 5 of elevation angle and azimuth of the objective 31. The computer 7 converts the digital signal 5 into an analog video signal symbolically representing the objective 31. It can be expected that this symbolic representation depends on the values of the azimuth and site angles. The video signal is applied to a video control circuit 7V to be inserted into a video signal scanning a whole screen 8 of the console 6. The computer 7 also provides, to circuit 7V, commands for positioning the image 41 of the image. objective 31 on 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 represented at the central point of the screen 8 and a crown 9 centered on this point is provided to receive the symbolic representation 41 of the objective 31. A deflector circuit of the circuit 7V is controlled from the positioning commands of the computer 7, that is to say as a function of the azimuth and elevation angles, in order to deflect the scanning beam from the screen 8 in such a way that the symbolic representation 41 is carried, relative to the center of the screen 8, in the direction of azimuth detected and that this symbolic representation 41 is more or less close to the internal edge of the crown 9 depending on whether the angle of site 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 for which the distance to the objective designation system 1 is known approximately are also marked in polar coordinates (distance, azimuth) in the circle surrounded by the crown 9, on which are reported, around the position 40 of the objective designation system 1, the positions of several weapon systems, here four, the covered area 44- 47 by each of these, as well as the only characteristic points of the landscape.

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 objective 31, the operator of the system can choose to activate the defense missile best placed to intercept objective 31 The estimated trajectory 42 followed by the latter and its estimated speed vector 43 are also represented associated with its image 41.
