  • the technical field of the invention is that of decoy devices, especially edge mines road.
  • Such decoy devices are placed at the head of a column of vehicles or tanks. They aim to triggering mines remotely from vehicles of combat in order to clear a route.
  • This system consists of a small remote-controlled vehicle which carries in the front part rods in the shape of needles which are sunk into the ground to initiate sensor mines pressure.
  • This vehicle also includes means for decoy allowing to generate an infrared signature close to that of a tank.
  • Such an arrangement allows trigger roadside mines (mines with horizontal action) which generally have infrared sensors.
  • the infrared decoy means described include a device which directs the exhaust gases from the engine of the vehicle to upper and / or lateral areas of the vehicle to heat them up.
  • the decoy device allows to ensure the safe triggering of on-board mines road while avoiding destruction of the vehicle deception.
  • the subject of the invention is therefore a decoy device, in particular a roadside mine, characterized in that that it comprises at least one flag fixed on a support, flag comprising at least one part ensuring transmission of radiation in the infrared spectrum.
  • the flag may consist of at least one flexible panel carrying at minus one heating element.
  • the heating element (s) may be connected to a temperature control means.
  • At least one temperature sensor may be placed at the near the heating element and be connected by means steering.
  • the heating element may include at least one element flexible conductor fixed at the level of a first part of the panel and following a curve whose shape ensures when heating element operation producing a thermal gradient between the first part and a second part of the panel.
  • the curve formed by the flexible conductive element may be a damped sinusoid.
  • the flag can be produced in one flexible rollable material and the support may include minus a reel.
  • the flag may consist of at least three flexible strips, at least one of these bands carrying a heating element.
  • the temperature of each heating element carried by a band can be slaved to a different value for each strip.
  • the heating element of each strip may include at least least one conductive element extending longitudinally between an upper edge and a lower edge of the strip.
  • Each band can carry a temperature sensor.
  • the flag may be made up of at least three plates, at least one plate carrying a heating element.
  • the plates can be linked together by removable connection means.
  • All plates arranged in at least one region of the flag will preferably have heating elements connected to a temperature regulation means, the temperature of each plate that can be controlled so individual.
  • the flag will be formed or else covered with a light-reflecting material.
  • the reflective material may be constituted by at minus a metallization layer.
  • the flag may be attached to a support affecting the form of a bracket attached to a front part of a vehicle, the flag carrying at least one ballast secured to a lower edge.
  • the vehicle may be remote operated and may carry means for generating an acoustic and / or seismic signal.
  • a decoy device 1 according to a first embodiment comprises a support 2 affecting the form of a gallows comprising an arm horizontal 2a connected by a first articulation 5 to an arm tilted 2b.
  • the bracket 2 is fixed by means of a second articulation 4 to a front part 3a of a vehicle 3 of which only the front wheels are shown here.

  • a second hydraulic cylinder 7 makes it possible to adjust the angle between the horizontal arm 2a and the inclined arm 2b.
  • the support 2 carries a flag 8 which is here constituted by two flexible panels 9a, 9b.
  • Each panel 9a, 9b is integral with an upper rod 10 which is suspended from the horizontal arm 2a by via flexible connection means 11, for example springs.
  • Each panel has a square shape of 2m side. He is wearing also weights 12 secured to its lower edge 13a, 13b.
  • the panels are uniformly stretched by the weights 12 and they form a substantially flat surface and vertical hanging from the stem 2.
  • Cylinders 6 and 7 allow the position of the flag 8 in relation to the ground.
  • the flatness of the flag is reinforced by staples 14 which link the panels together.
  • the panels are made from a sheet of plastic or woven material of a few tenths of a mm thick, they have a reflective surface of the light on each side, surface which is obtained for example by metallization.
  • Each panel has a heating element 15a, 15b which consists of a flexible conductive element which is fixed at a first part 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 carries the clips 14 of fixation.
  • the conductive elements will be produced for example by screen printing of an electrically conductive composition or by fixing flexible metallic conductors to the panel surface. If the panel material is good thermal insulator, we can also have an element heating on each side of the panel to ensure infrared emissivity of the same level on both sides of the panel.
  • the conductive elements 15a and 15b are connected independently of each other to a current source 18 which is a means of controlling the temperature of the elements conductors.
  • the control means 18 will include a generator current allowing intensity control.
  • the temperature control will be ensured by the control means 18 from a programming of desired temperatures (stored in medium 18), and thanks to a reading of the real temperature of the panels 9a, 9b obtained by the temperature sensors 19a, 19b which are also connected to the control module 18.
  • the temperature sensors will for example be thermistors or thermo couples.
  • the heating elements 15a, 15b have a shape which ensures during heating element operation producing a thermal gradient between the first part 17a, 17b of the panel and a second peripheral part 20a, 20b of the sign.
  • This shape here is substantially a sinusoidal curve damped with maximum amplitude at the side 16a, 16b of the panel and decreases when the heating element goes away on this side.
  • the control means 18 will be adjusted so as to obtain a temperature at the central zone 17a, 17b of the flag 8 which will be between 5 ° and 10 ° higher than the ambient temperature over an area of approximately 0.5 m 2 .
  • the emissivity in the Infrared domain of the flag is therefore close to that of an armored vehicle.
  • the energy consumption of such a device is some tens of watt hours, the batteries of the sufficient to ensure the supply of such energy.
  • the shape of the conductors will be chosen so as to ensure the desired temperature level.
  • the sensors temperature 19a, 19b will control the level of temperature.
  • the flag according to the invention constitutes a decoy for a roadside mine 21.
  • a mine is disposed usually on a tripod 22 along a route of passage of armored vehicles. It includes a target 23 which generally combines infrared detection and a laser rangefinder.
  • the device according to the invention When the device according to the invention passes in front of the target sensor 23 of mine 21, the latter detects a hot spot whose infrared signature is close to that of a vehicle.
  • the rangefinder laser beam is reflected by the metallized surface of the panels 9a, 9b, which for the mine provides confirmation of the presence of a target of a length equivalent to that of a combat vehicle.
  • the firing of mine 21 is therefore caused by the device lure according to the invention.
  • the flexible panels 9a, 9b are light and inexpensive, they are easily replaced as a result of their destruction by the mine, and the demining vehicle retains all of its mobility.
  • the panels can also be sufficiently thin so as not to trigger the explosion of the projectile fired by the mine during its impact on the flag.
  • a device could be defined in which the flag would consist of a single panel.
  • one or more can be provided rewinder systems integral with the support and allowing the winding of each panel.
  • the reels will be preferably motorized. This winding is made possible by the flexibility of the material of the panels. We thus facilitates the mobility of the device, the panels can be easily deployed or folded. The length deployed of each panel which can also be modified.
  • each panel in the form of a sheet of a conductive polymer of the heat to which a conductive mesh will be applied flexible.
  • This structure will be covered on both sides by a protective sheet which will be reflective (by example metallized plastic).
  • This structure will be easily rollable.
  • Figure 2 shows a decoy device according to a second embodiment of the invention.
  • 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 flexible curtain. Each strip is metallized on its two sides to ensure its reflective character.
  • some of the bands 24 carry a heating element 15 consisting of an element flexible conductor bonded or screen printed on the surface of the band (and possibly symmetrically on both sides of each strip to ensure infra-emissivity the same level on either side of the flag).
  • the bands 24a, 24b, 24c, 24d, 24e, 24f and 24g carry a heating element (respectively 15a, 15b, 15c, 15d, 15th, 15f and 15g).
  • Each heating element 15 is connected to the means 18 controlling its temperature.
  • 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 carried 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 side bands.
  • the curve formed by the juxtaposition of different heating elements have here substantially the shape a damped sinusoid on either side of the strip central 24a.
  • Each strip 24 can also carry a temperature 19 which is connected to the control means 18 and which allows measurement of the actual strip temperature considered.
  • the temperature of each heating element carried by a strip is slaved by the control means 18 to a value different for each band.
  • the operation of this device is the same as that previously described.
  • the mine sensor 23 will detect a hot spot at a central part 17 of the flag.
  • the range finder laser will be reflected from the surface of the bands and the mine will be initiated.
  • the strips can be placed with the hottest parts backwards so simulate vehicles whose hot spot is the pot exhaust (located towards the rear).
  • FIG. 3 shows an alternative embodiment in which each strip 24 carries at least one conductive element flexible 15 which extends longitudinally between an edge upper 25 and a lower edge 13 of the strip 24 and which has at least one ripple.
  • the band will wear possibly two symmetrical conductors, one on each face.
  • the flag 8 here comprises ten bands numbered 24a to 24d.
  • the central bands 24e, 24f and 24g have conductors 15 which are wavy evenly over substantially the entire length of the strip.
  • the front strips 24a, 24b, 24c and 24d have conductors 15 which are waved regularly only at the level of the lower half of the strip.
  • the rear bands 24, 24i and 24d also have conductors which are only wavy at the level of half bottom of the strip, but the undulations made on these bands have a variable shape along each band. Ripples of reduced period 26 are thus followed by ripples 27 of wider period.
  • Each conductive element 15 is connected by means of temperature control 18.
  • a temperature sensor 19 being moreover arranged at the level of each strip at near the area heated by the conductive element.
  • Zone B will be controlled at a temperature that will be between 15 ° and 20 ° above room temperature and which will be greater than that of zone A (which will itself be brought to a temperature between 5 ° and 10 ° above the temperature ambient).
  • the whole flag appears roughly the silhouette of an armored vehicle A whose compartment motor corresponds to zone B.
  • the advantage of this variant is that it is easy to move the hot spot to simulate different vehicles (for example to the rear exhaust pipe).
  • Figure 4 shows a third embodiment of the device according to the invention.
  • flag 8 is produced by a mosaic of plates 28 which are connected to each other by removable connecting means 29, by example by repositionable rings.
  • the plates will be made for example of aluminum.
  • All plates are covered with material light reflecting and some plates have heating elements, for example resistors electrical or conductors (not shown) arranged on each side of each plate and connected by means of temperature control 18.
  • heating elements for example resistors electrical or conductors (not shown) arranged on each side of each plate and connected by means of temperature control 18.
  • Each hot plate will also carry a temperature (not shown).
  • each plate can be controlled from individually by means 18, so it is possible to give flag 8 an infrared signature close to that of a real vehicle.
  • flag 8 an infrared signature close to that of a real vehicle.
  • Figure 4 a number of heated plates, arranged substantially in the middle of the flag 8 and which delimit the silhouette Z of a armored vehicle.
  • the plates 28a and 28b are heated to a temperature higher than that of their neighbors so as to appear simulate the location of the engine compartment.
  • the seismic signal can be obtained using wheels or tracks integral with the vehicle and having a profile appropriate.
  • the vehicle 3 can be teleoperated to starting, for example, from a follower vehicle. We will thus increase the security of the demining operation.
  • the invention can finally be applied to other types of deception than that of roadside mines, especially at the simulation of armored vehicles for site protection or an area against attacks by guided missiles infrared.
