Description

Le domaine technique de l'invention est celui des dispositifs de leurrage, notamment des mines de bord de route.The technical field of the invention is that of decoying devices, including road.

De tels dispositifs de leurrage sont placés en tête d'une colonne de véhicules ou de chars. Ils ont pour but de provoquer le déclenchement des mines à distance des véhicules de combat de façon à dégager un itinéraire.Such decoy devices are placed at the head of a column of vehicles or tanks. They aim to triggering mines from vehicles to clear a route.

On connaít par le brevet FR2748560 un système de déminage permettant de déclencher les mines terrestres posées, enterrées ou disposées en bord de route.Patent FR2748560 discloses a demining system triggering landmines laid, buried or arranged along the road.

Ce système est constitué par un petit véhicule téléopéré qui porte en partie avant des tiges en forme d'aiguilles qui sont enfoncées dans le sol pour initier les mines à senseur de pression. Ce véhicule comporte également des moyens de leurrage permettant d'engendrer une signature infra rouge proche de celle d'un char. Une telle disposition permet d'assurer le déclenchement des mines de bord de route (mines à action horizontale) qui sont généralement dotées de senseurs infrarouges.This system consists of a small teleoperated vehicle which carries in part before needle-shaped stems that are driven into the ground to initiate sensor mines pressure. This vehicle also includes means of decoy to generate an infrared signature close to that of a tank. Such an arrangement allows ensure the activation of roadside mines (mines horizontal action) which are generally equipped with infrared sensors.

Les moyens de leurrage infra rouge décrits comprennent un dispositif qui dirige les gaz d'échappement du moteur du véhicule vers des zones supérieures et/ou latérales du véhicule afin d'échauffer ces dernières.The infrared decoy means disclosed include a device that directs the engine exhaust from the vehicle to higher and / or lateral areas of the vehicle to warm them up.

L'inconvénient d'un tel dispositif est que le véhicule de déminage provoque le tir d'une mine de bord de route directement sur lui. Il en résulte une destruction plus ou moins complète du véhicule démineur, ce qui impose un remplacement ou bien une remise en état longue et coûteuse directement sur le théâtre d'opérations et au milieu d'une zone minée.The disadvantage of such a device is that the vehicle of demining causes firing of a roadside mine directly on him. This results in more destruction or less complete vehicle demining, which imposes a replacement or a long and expensive overhaul directly in the theater of operations and in the middle of a mined area.

C'est le but de l'invention que de proposer un dispositif de leurrage ne présentant pas de tels inconvénients.It is the object of the invention to provide a device decoys do not have such drawbacks.

Ainsi le dispositif de leurrage selon l'invention permet d'assurer de façon sûre le déclenchement des mines de bord de route tout en évitant une destruction du véhicule de leurrage.Thus the decoy device according to the invention allows to ensure the safe release of shipboard mines from route while avoiding a destruction of the vehicle of decoy.

Each panel has a heating element 15a, 15b which is constituted by a flexible conductive element which is fixed at a first portion 17a, 17b of the panel, located substantially in the middle of the side 16a, 16b of the panel 9a, 9b which is in contact with the neighboring panel and wears the clips 14 of fixation.

Les éléments conducteurs seront réalisés par exemple par sérigraphie d'une composition électriquement conductrice ou par fixation de conducteurs métalliques souples sur la surface du panneau. Si le matériau du panneau est un bon isolant thermique, on pourra également disposer un élément chauffant sur chaque face du panneau afin d'assurer une émissivité des infra rouges de même niveau de part et d'autre du panneau.The conductive elements will be made for example by screen printing of an electrically conductive composition or by attaching flexible metal conductors to the panel surface. If the panel material is a good one thermal insulation, it will also be possible to have an element heated on each side of the panel to ensure Emissivity of infra red of the same level on both sides of the panel.

Les éléments conducteurs 15a et 15b sont reliés indépendamment l'un de l'autre à une source de courant 18 qui constitue un moyen de pilotage de la température des éléments conducteurs.The conductive elements 15a and 15b are connected independently of one another to a current source 18 which constitutes a means of controlling the temperature of the elements conductors.

Le moyen de pilotage 18 comprendra un générateur de courant permettant un pilotage de l'intensité.The control means 18 will comprise a generator of current for controlling the intensity.

L'asservissement des températures sera assuré par le moyen de pilotage 18 à partir d'une programmation des températures souhaitées (mises en mémoire dans le moyen 18), et grâce à une lecture de la température réelle des panneaux 9a,9b obtenue par les capteurs de température 19a,19b qui sont également reliés au module de pilotage 18.The enslavement of temperatures will be ensured by the means of piloting 18 from a programming of desired temperatures (stored in the means 18), and thanks to a reading of the actual temperature of the panels 9a, 9b obtained by the temperature sensors 19a, 19b which are also connected to the control module 18.

Les capteurs de température seront par exemple des thermistances ou des thermo couples.The temperature sensors will for example be thermistors or thermo couples.

Suivant une autre caractéristique de l'invention, les éléments chauffants 15a, 15b ont une forme qui assure lors du fonctionnement de l'élément chauffant la production d'un gradient thermique entre la première partie 17a,17b du panneau et une deuxième partie périphérique 20a,20b du panneau.According to another characteristic of the invention, the heating elements 15a, 15b have a shape which ensures operation of the heating element the production of a thermal gradient between the first portion 17a, 17b of the panel and a second peripheral portion 20a, 20b of sign.

Cette forme est ici sensiblement une courbe sinusoïdale amortie dont l'amplitude est maximale au niveau du côté 16a,16b du panneau et décroít lorsque l'élément chauffant s'éloigne de ce côté.This shape is here substantially a sinusoidal curve damped with maximum amplitude at the side 16a, 16b of the panel and decreases when the heating element go away on that side.

Il résulte d'une telle forme du conducteur une longueur d'élément chauffant plus importante au niveau de la première partie 17a,17b du panneau qu'au voisinage de la partie périphérique 20a,20b. La température obtenue sera donc plus forte au niveau de la première partie 17a,17b que dans le reste du panneau.It results from such a shape of the driver a length heating element at the level of the first part 17a, 17b of the panel in the vicinity of the part device 20a, 20b. The temperature obtained will therefore be higher strong in the first part 17a, 17b that in the rest of the panel.

Il en résulte (du point de vue du rayonnement infra rouge émis par les éléments chauffants 15a,15b) l'apparition d'un point chaud au niveau des parties 17a,17b, soit sensiblement au milieu du drapeau 8 formé par les deux panneaux 9a,9b, ainsi qu'un gradient de température autour de ce point chaud.The result is (from the point of view of infrared radiation emitted by the heating elements 15a, 15b) the appearance of a hot spot at parts 17a, 17b, substantially in the middle of the flag 8 formed by the two panels 9a, 9b, as well as a temperature gradient around this hot spot.

Le moyen de pilotage 18 sera réglé de façon à obtenir une température au niveau de la zone centrale 17a,17b du drapeau 8 qui sera entre 5° et 10° supérieure à la température ambiante sur une surface d'environ 0,5 m2.The control means 18 will be set to obtain a temperature at the central zone 17a, 17b of the flag 8 which will be between 5 ° and 10 ° greater than the ambient temperature over an area of approximately 0.5 m 2 .

L'emissivité dans le domaine Infrarouge du drapeau est donc proche de celle d'un véhicule blindé.The emissivity in the Infrared range of the flag is so close to that of an armored vehicle.

La consommation en énergie d'un tel dispositif est de quelque dizaines de Wattheure environ, les batteries du véhicule suffisent à assurer la fourniture d'une telle énergie.The energy consumption of such a device is a few tens of hours, the batteries of the vehicle are sufficient to ensure the provision of such energy.

La forme des conducteurs sera choisie de façon à assurer le niveau de température souhaité. Les capteurs de température 19a,19b permettront de piloter le niveau de température.The shape of the drivers will be chosen to ensure the desired temperature level. The sensors of temperature 19a, 19b will control the level of temperature.

Le drapeau selon l'invention constitue un leurre pour une mine de bord de route 21. Une telle mine est disposée habituellement sur un trépied 22 le long d'un itinéraire de passage de véhicules blindés. Elle comporte un capteur de cible 23 qui associe généralement une détection infra rouge et un télémètre laser.The flag according to the invention constitutes a decoy for a roadside mine 21. Such a mine is arranged usually on a tripod 22 along a route of passage of armored vehicles. It includes a sensor target 23 which usually associates an infrared detection and a laser range finder.

Lorsque le dispositif selon l'invention passe devant le capteur de cible 23 de la mine 21, ce dernier détecte un point chaud dont la signature infra rouge est proche de celle d'un véhicule. Le rayon laser du télémètre est réfléchi par la surface métallisée des panneaux 9a,9b, ce qui pour la mine permet d'assurer la confirmation de la présence d'une cible d'une longueur équivalente à celle d'un véhicule de combat.When the device according to the invention passes the target sensor 23 of the mine 21, the latter detects a hot spot whose infrared signature is close to that of a vehicle. The laser beam of the rangefinder is reflected by the metallized surface of the panels 9a, 9b, which for the mine allows to confirm the presence of a target of a length equivalent to that of a combat vehicle.

Le tir de la mine 21 est donc provoqué par le dispositif leurre selon l'invention. The firing of the mine 21 is therefore caused by the device decoy according to the invention.

Les panneaux souples 9a, 9b sont légers et peu coûteux, ils sont facilement remplacés comme suite à leur destruction par la mine, et le véhicule de déminage conserve toute sa mobilité. Les panneaux peuvent par ailleurs être suffisamment minces pour ne pas déclencher l'explosion du projectile tiré par la mine lors de son impact sur le drapeau.The flexible panels 9a, 9b are light and inexpensive, they are easily replaced as a result of their destruction mine, and the demining vehicle retains all its mobility. The panels can also be sufficiently thin not to trigger the shot projectile explosion by the mine during its impact on the flag.

A titre de variante on pourrait définir un dispositif dans lequel le drapeau serait constitué d'un seul panneau.Alternatively, a device could be defined in which the flag would consist of a single panel.

Avantageusement on pourra prévoir un ou plusieurs systèmes enrouleurs solidaires du support et permettant l'enroulement de chaque panneau. Les enrouleurs seront de préférence motorisés. Cet enroulement est rendu possible par la souplesse du matériau constitutif des panneaux. On facilite ainsi la mobilité du dispositif, les panneaux pouvant être facilement déployés ou repliés. La longueur déployée de chaque panneau pouvant également être modifiée.Advantageously one or more may be provided winding systems secured to the support and allowing the winding of each panel. The reels will be motorized preference. This winding is made possible by the flexibility of the constituent material of the panels. We thus facilitates the mobility of the device, the panels can be easily deployed or folded. The length deployed from each panel that can also be changed.

On pourra à titre de variante réaliser chaque panneau sous la forme d'une feuille d'un polymère conducteur de la chaleur sur laquelle sera appliqué un treillis conducteur souple. Cette structure sera recouverte sur ses deux faces par une feuille de protection qui sera réfléchissante (par exemple une matière plastique métallisée).We can alternatively make each panel in the form of a sheet of a conductive polymer of the heat on which will be applied a conducting lattice flexible. This structure will be covered on both sides by a protective sheet that will be reflective (by example a metallized plastic material).

Cette structure sera facilement enroulable.This structure will be easily rollable.

On pourra ainsi réaliser un dispositif comportant un premier panneau chauffé (à une température comprise entre 5° et 10° au dessus de la température ambiante) qui sera suivi d'un deuxième panneau non chauffé (mais ayant des capacités réfléchissantes).It will thus be possible to produce a device comprising a first heated panel (at a temperature between 5 ° and 10 ° above room temperature) which will be followed a second unheated panel (but with reflective).

La figure 2 présente un dispositif de leurrage selon un deuxième mode de réalisation de l'invention.Figure 2 shows a decoy device according to a second embodiment of the invention.

Ce dispositif diffère du précédent par la structure du drapeau 8 qui n'est pas ici formé par deux panneaux mais par la juxtaposition de plusieurs bandes rectangulaires 24 à la manière d'un rideau souple. Chaque bande est métallisée sur ses deux faces pour assurer son caractère réfléchissant. This device differs from the previous one by the structure of the flag 8 which is not here formed by two panels but by the juxtaposition of several rectangular strips 24 at the way of a soft curtain. Each band is metallized on both sides to ensure its reflective character.

Elle est suspendue par son bord supérieur à la tige 10 et porte des lests 12 attachés à son bord inférieur. Les bandes ont une largeur réduite (environ 150 mm) pour une longueur de l'ordre de 2 m. Une telle configuration permet d'obtenir un drapeau 8 plus souple et pouvant notamment d'adapter plus facilement aux irrégularités du sol.It is suspended by its upper edge at the stem 10 and carries weight 12 attached to its lower edge. The strips have a reduced width (about 150 mm) for a length of the order of 2 m. Such a configuration allows to obtain a flag 8 more flexible and in particular to adapt more easily to irregularities of the ground.

Conformément à l'invention certaines des bandes 24 portent un élément chauffant 15 constitué par un élément conducteur souple collé ou sérigraphié sur la surface de la bande (et éventuellement d'une façon symétrique sur les deux faces de chaque bande afin d'assurer une émissivité infra rouge de même niveau de part et d'autre du drapeau).According to the invention some of the bands 24 carry a heating element 15 constituted by an element soft conductor glued or screen-printed on the surface of the band (and possibly in a symmetrical way on both sides of each band to ensure an emissivity infra red of the same level on both sides of the flag).

Sur la figure 2 seules les bandes 24a, 24b, 24c, 24d, 24e, 24f et 24g portent un élément chauffant (respectivement 15a, 15b, 15c, 15d, 15e, 15f et 15g).In FIG. 2 only the strips 24a, 24b, 24c, 24d, 24e, 24f and 24g carry a heating element (respectively 15a, 15b, 15c, 15d, 15e, 15f and 15g).

Chaque élément chauffant 15 est relié au moyen 18 assurant le pilotage de sa température.Each heating element 15 is connected to the means 18 controlling the temperature.

La surface chauffante des éléments chauffants 15 est différente suivant la bande considérée. Ainsi la bande centrale 24a porte un élément chauffant 15a dont la longueur est supérieure à celle des éléments chauffants portés par les bandes voisines 24b et 24c. Les bandes périphériques 24f et 24g sont celles pour lesquelles l'élément chauffant a une longueur minimale. La bande centrale pourra donc être portée à une température supérieure à celle des bandes latérales.The heating surface of the heating elements 15 is different depending on the band considered. So the band central 24a carries a heating element 15a whose length is greater than that of the heating elements worn by the neighboring bands 24b and 24c. The peripheral bands 24f and 24g are those for which the heating element has a minimum length. The central band can therefore be worn at a temperature higher than that of the sidebands.

Globalement, la courbe formée par la juxtaposition des différents éléments chauffants a ici sensiblement la forme d'une sinusoïde amortie de part et d'autre de la bande centrale 24a.Overall, the curve formed by the juxtaposition of different heating elements here has substantially the shape of a sinusoid damped on both sides of the band central 24a.

Chaque bande 24 peut porter également un capteur de température 19 qui est relié au moyen de pilotage 18 et qui permet la mesure de la température réelle de la bande considérée.Each band 24 can also carry a sensor of temperature 19 which is connected to the control means 18 and which allows measurement of the actual temperature of the band considered.

La température de chaque élément chauffant porté par une bande est asservie par le moyen de pilotage 18 à une valeur différente pour chaque bande. The temperature of each heating element carried by a band is enslaved by the steering means 18 to a value different for each band.

Il résulte d'une telle configuration que la température de la bande centrale est supérieure à celle des bandes latérales et qu'il y a donc un gradient thermique entre la bande centrale 24a et les bandes latérales.It results from such a configuration that the temperature of the central band is greater than that of the bands side and that there is therefore a thermal gradient between central band 24a and the sidebands.

Le fonctionnement de ce dispositif est le même que celui décrit précédemment. Le capteur 23 de la mine va détecter un point chaud au niveau d'une partie centrale 17 du drapeau. Le laser du télémètre va être réfléchi par la surface des bandes et la mine se trouvera initiée.The operation of this device is the same as that previously described. The sensor 23 of the mine will detect a hot spot at a central portion 17 of the flag. The laser rangefinder will be reflected by the surface of the bands and the mine will be initiated.

En plus de son meilleur suivi du terrain, ce mode de réalisation présente l'avantage d'être facilement réparable après déclenchement d'une mine. En effet, il suffit le plus souvent de remplacer une seule bande détruite par la mine, ce qui est plus facile et moins coûteux que de remplacer l'ensemble du drapeau leurre.In addition to its better terrain monitoring, this mode of realization has the advantage of being easily repairable after triggering a mine. Indeed, it is enough often to replace a single band destroyed by the mine, this which is easier and cheaper than replacing the whole lure flag.

A titre de variante on pourra disposer les bandes comportant les parties les plus chaudes vers l'arrière afin de simuler les véhicules dont le point chaud est le pot d'échappement (situé vers l'arrière).As a variant we can arrange the bands with the hottest parts to the rear so to simulate vehicles whose hot spot is the pot exhaust (located to the rear).

La figure 3 montre une variante de réalisation dans laquelle chaque bande 24 porte au moins un élément conducteur souple 15 qui s'étend longitudinalement entre un bord supérieur 25 et un bord inférieur 13 de la bande 24 et qui présente au moins une ondulation. La bande portera éventuellement deux conducteurs symétriques, un sur chaque face.Figure 3 shows an alternative embodiment in each strip 24 carries at least one conductive element flexible 15 which extends longitudinally between an edge superior 25 and a lower edge 13 of the band 24 and which has at least one undulation. The band will wear possibly two symmetrical conductors, one on each face.

Le drapeau 8 comporte ici dix bandes numérotées 24a à 24j. Les bandes centrales 24e, 24f et 24g ont des conducteurs 15 qui sont ondulés d'une façon régulière sur sensiblement toute la longueur de la bande.The flag 8 here comprises ten bands numbered 24a to 24j. The 24th, 24f and 24g central bands have drivers 15 which are corrugated in a regular manner on substantially the entire length of the band.

Les bandes avant 24a, 24b, 24c et 24d ont des conducteurs 15 qui ne sont ondulés régulièrement qu'au niveau de la moitié inférieure de la bande.The front bands 24a, 24b, 24c and 24d have drivers 15 that are waved regularly only at the level of the lower half of the band.

Les bandes arrières 24h, 24i et 24j ont également des conducteurs qui ne sont ondulés qu'au niveau de la moitié inférieure de la bande, mais les ondulations réalisées sur ces bandes ont une forme variable le long de chaque bande. Des ondulations de période réduite 26 sont ainsi suivies par des ondulations 27 de période plus large.The rear bands 24, 24i and 24j also have drivers who are only wavy at the level of half bottom of the band, but the ripples performed on these bands have a variable shape along each band. Ripples of reduced period 26 are thus followed by ripples 27 of wider period.

Chaque élément conducteur 15 est relié au moyen de pilotage de sa température 18. Un capteur de température 19 étant par ailleurs disposé au niveau de chaque bande au voisinage de la zone chauffée par l'élément conducteur.Each conductive element 15 is connected by means of controlling its temperature 18. A temperature sensor 19 being otherwise disposed at the level of each band at vicinity of the heated zone by the conductive element.

Une telle configuration permet de délimiter sur le drapeau 8 deux zones de températures (hachurées sur la figure 3) :

  • une zone A correspondant aux éléments conducteurs ayant des ondulations de période longue et qui comprend les bandes 24e,24f et 24g, la moitié inférieure des bandes 24a,24b,24c et 24d, et le quart inférieur des bandes 24h,24i et 24j.
  • une zone B correspondant aux éléments conducteurs ayant des ondulations de période courte et qui comprend un quart des bandes 24h,24i et 24j.
Such a configuration makes it possible to define on the flag 8 two temperature zones (hatched in FIG. 3):
  • a zone A corresponding to the conductive elements having long period corrugations and which comprises the bands 24e, 24f and 24g, the lower half of the bands 24a, 24b, 24c and 24d, and the lower quarter of the bands 24, 24i and 24j.
  • a zone B corresponding to the conductive elements having ripples of short period and which comprises a quarter of the bands 24, 24i and 24j.

La zone B sera asservie à une température qui sera entre 15° et 20° au dessus de la température ambiante et qui sera supérieure à celle de la zone A (qui sera elle même portée à une température entre 5° et 10° au dessus de la température ambiante). L'ensemble du drapeau figure ainsi grossièrement la silhouette d'un véhicule blindé A dont le compartiment moteur correspond à la zone B.Zone B will be slaved to a temperature that will be between 15 ° and 20 ° above the ambient temperature and which will be greater than that of zone A (which will itself be a temperature between 5 ° and 10 ° above the temperature ambient). The entire flag is thus roughly the silhouette of an armored vehicle A whose compartment motor corresponds to zone B.

L'avantage de cette variante est qu'il est facile de déplacer le point chaud pour simuler des véhicules différents (par exemple au pot d'échappement vers l'arrière).The advantage of this variant is that it is easy to move the hot spot to simulate different vehicles (eg exhaust muffler to the rear).

La figure 4 montre un troisième mode de réalisation du dispositif selon l'invention.Figure 4 shows a third embodiment of the device according to the invention.

Ce mode diffère du précédent en ce que le drapeau 8 est réalisé par une mosaïque de plaques 28 qui sont reliées les unes aux autres par des moyens de liaison démontables 29, par exemple par des anneaux repositionnables.This mode differs from the previous one in that flag 8 is made by a mosaic of plates 28 which are connected to each other by dismountable connecting means 29, by example by repositionable rings.

Les plaques seront réalisées par exemple en aluminium.The plates will be made for example of aluminum.

Toutes les plaques sont recouvertes d'un matériau réfléchissant la lumière et certaines plaques sont dotées d'éléments chauffants, par exemple des résistances électriques ou des conducteurs (non représentés) disposés de part et d'autre de chaque plaque et reliés au moyen de pilotage de la température 18.All plates are covered with a material reflecting light and some plates are endowed heating elements, for example resistors electrical devices or conductors (not shown) arranged on each side of each plate and connected by means of temperature control 18.

Chaque plaque chauffante portera également un capteur de la température (non représenté).Each hotplate will also carry a sensor the temperature (not shown).

Avec une telle configuration il est possible de donner à chacune des plaques équipée de moyens chauffants une température donnée.With such a configuration it is possible to give to each of the plates equipped with heating means a given temperature.

La température de chaque plaque peut être pilotée de façon individuelle par les moyens 18, il est donc possible de donner au drapeau 8 une signature infra rouge proche de celle d'un véhicule réel. On a ainsi ombré sur la figure 4 un certain nombre de plaques chauffées, disposées sensiblement au milieu du drapeau 8 et qui délimitent la silhouette Z d'un véhicule blindé. Dans cette silhouette Z, les plaques 28a et 28b sont chauffées à une température supérieure à celle de leurs voisines de façon à figurer simuler la localisation du compartiment moteur.The temperature of each plate can be controlled from individual way by means 18, so it is possible to give the flag 8 an infrared signature close to that of a real vehicle. We have thus shaded in Figure 4 a number of heated plates, arranged substantially in the middle of the flag 8 and which delimit the Z silhouette of a armored vehicle. In this silhouette Z, the plates 28a and 28b are heated to a temperature above that of their neighbors so as to appear to simulate the location of the engine compartment.

Là encore le tir de la mine 21 provoquera la destruction d'une ou deux plaques seulement qu'il sera facile de remplacer rapidement.Again the firing of the mine 21 will cause the destruction only one or two plates that it will be easy to replace quickly.

On pourra compléter le dispositif de leurrage selon n'importe lequel des modes de réalisation précédemment décrits en prévoyant des moyens portés par le véhicule 3 et permettant la génération d'un signal acoustique et/ou sismique. En effet, les mines de bord de route sont fréquemment dotées de moyens de veille acoustique. Il suffira par exemple d'enregistrer le bruit engendré par un ou plusieurs véhicules blindés et de diffuser ce bruit à partir du véhicule 3 au moyen de hauts parleurs.We can complete the decoy device according to any of the embodiments previously described by providing means carried by the vehicle 3 and allowing the generation of an acoustic signal and / or seismic. Indeed, roadside mines are frequently equipped with acoustic monitoring means. It will suffice for example to record the noise generated by one or several armored vehicles and spread this sound from vehicle 3 using loudspeakers.

On pourra à titre de variante assurer simplement une amplification du bruit du véhicule portant le dispositif selon l'invention. As an alternative, we can simply ensure amplification of the noise of the vehicle carrying the device according to the invention.

Le signal sismique pourra être obtenu à l'aide de roues ou de chenilles solidaires du véhicule et ayant un profil approprié.The seismic signal can be obtained using wheels or of crawlers secured to the vehicle and having a profile appropriate.

Avantageusement, le véhicule 3 pourra être téléopéré à partir par exemple d'un véhicule suiveur. On accroítra ainsi la sécurité de l'opération de déminage.Advantageously, the vehicle 3 can be teleoperated to for example from a follower vehicle. We will increase the safety of the demining operation.

On pourra également lier le drapeau à un châssis téléopéré. Dans tous les cas le drapeau devra être séparé d'un véhicule suiveur par un zone libre afin que le drapeau puisse effectivement être reconnu comme un véhicule.We can also link the flag to a chassis remotely operated. In all cases the flag will have to be separated of a follower vehicle by a free zone so that the flag can actually be recognized as a vehicle.

L'invention peut enfin être appliqué à d'autre type de leurrage que celui des mines de bord de route, notamment à la simulation de véhicules blindés pour la protection d'un site ou d'une zone contre les attaques par les missiles à guidage infra rouge.The invention can finally be applied to other types of deception as that of roadside mines, especially at the simulation of armored vehicles for the protection of a site or an area against attacks by guided missiles infra red.
