Definitions

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.
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.
the round trip time of the wave allows, in addition, calculate the distance from the lens to the detector.
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.
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.
the present invention aims, in the application of a passive detector, to remove this risk.
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.
the weapon system can acquire it during scanning, for example through self-directing narrow-field defense missiles.
the scan may be just an electronic scan a sighting system.
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.
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.
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.
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.
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.
the weapon system 11 proceeds to scanning in a plane containing the direction of objective 10.
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.
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.
the weapon system has no detector, it suitable as it fires ammunition in all directions firing possibilities indicated above.
the objective designation system 1 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.
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.
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.
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.
