Definitions

  • Objective designation provides information to a weapon system to point the weapon in the direction of an objective, or target.
  • a target designation system includes detection means for monitoring a determined volume of space and for detecting the direction of any radiation from a target, in order to provide the weapon system with relative direction information of the target. 'goal.
  • the first type of detector is associated with a transmitter to constitute an active detection unit, such as a radar or a sonar.
  • the objective is "illuminated" by the transmitter and the detector receives a reflected wave.
  • the travel time back and forth of the wave also makes it possible to calculate the distance from the objective to the detector. Having the direction and the distance, the detector can thus supply, to computers of the weapon system, the position of the objective in any system of absolute coordinates, directly interpretable by the computers. As a result, the detector and the weapon system can be separated from each other, which makes it possible to shelter the computers by placing them in protected or camouflaged rooms, while there is the risk that the transmitter, detectable, and associated with the detector, is not destroyed by an enemy missile.
  • the second type of detector is passive and includes a sensor, generally an infrared sensor. Its discretion better protects it from enemy missiles, but there is always a risk of destruction if it is itself detected or if it is in the vicinity of a potential target for an enemy missile.
  • the detector was active with the risk that it would be destroyed, or the detector was passive, with the risk that not only the detector but also the weapon system would be destroyed.
  • the present invention aims, in the application of a passive detector, to eliminate this risk.
  • the invention relates to a method for operating a weapon system associated with a passive detector objective designation system, characterized in that the weapon system is deported relative to the designation system.
  • objective we determine the relative position of the two systems, from an objective direction provided by the objective designation system we determine a set of possible positions of the objective in a reference linked to the weapon system as well that the directions of fire passing through these possible positions and the weapon system, and the weapon system sweep these directions of fire.
  • the weapon system can acquire it during scanning, for example by self-directing narrow-field defense missiles. It will be understood that the scanning can only be an electronic scanning of a sighting system.
  • the invention also relates to an assembly, for the implementation of the method of the invention, of a weapon system and an associated objective designation system which comprises a passive detector and means for determining direction objective, characterized by the fact that the weapon system is offset from and linked to the objective designation system and that means are provided for determining the relative position of the two systems and of the firing direction determining means controlled by the detector and arranged to control the firing as a function of the objective direction and of the relative position of the two systems.
  • 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.
  • 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.
  • 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.
  • 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 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 reference linked to the weapon system 11 and calculates directions of corresponding shots 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 lens designation and control scanning through link 20.
  • the weapon system 11 proceeds to scanning in a plane containing the objective direction 10.
  • the weapon system 11 has, as here, missiles
  • 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.
  • the weapon 11 can determine its distance from the objective 31 in order to compare it with its firing range and provide a corresponding indication to an operator of the system.
  • the weapon system does not have any detector, it should then fire ammunition in all possible directions of fire indicated above.
  • 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.
  • 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 for receiving 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 edge internal of the crown 9 depending on whether the detected site angle is more or less close to the lower value of its detection range.
  • Objectives for which the distance to the 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 plotted, around the position 40 of the system 1 objective designation, the positions of several weapon systems, here four, the area covered 44-47 by each of these, as well as the only characteristic points of the landscape.
  • 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.
