    Visor for a weapon system to be fired by a person with a search head.
    The invention relates to a visor for a weapon system to be fired by a person provided with a search head, wherein the search head has an image-supplying detector on which an image of an object in the field of view of the search head can be obtained and that a digital image supplies.
    There are weapon systems in which a rocket-propelled rocket is fired from a launch tube. The launch tube is carried by an end and is aimed at the target. There are weapon systems of this type in which the rocket has a search head that picks up the target and sends the rocket to the target by means of control surfaces. There are rockets in which an imaging optical system displays an image of an object on a detector providing an image. The image-supplying detector is a two-dimensional arrangement of detector elements. Each detector element comprises an image element (pixel) of the image of the object. From this an "electronic image" is obtained in the form of a digital image. The location of the recorded target is determined from the digital image by signal processing means, from which a control signal for the rocket is then derived.
    The detector operates in the usual manner in the infrared region. The detector then delivers an infrared image of the object and addresses it as a target on hot objects, such as aircraft engines.
    When bombarding aircraft, the launching tube must be aimed at least practically at the target to be hit. In this regard, a calculation and design are to be taken into account, that is to say that the longitudinal axis of the launch tube must be offset in the direction of movement of the target and upwards relative to the line of sight to the target.
    Known weapon systems of this type have a visor mounted on the launch tube with a keep and pellet. The visor has a cross-hairs and a frame with three marks for retention and design that is offset from the cross-hairs. Depending on the situation, so depending on whether the target moves in the field of vision from left to right or from right to left or towards the shooter, the target is covered with the right, left or middle mark.
    Known visors of this type require accommodation of the eye alternately on the target and on the keep-and-grain device. The field of view is small. As a result, there is a danger that the target will be lost sight of. The goal is often difficult to observe. As a rule, an observer with binoculars is present next to the shooter. Pointing the launcher at the target requires an assessment of the situation by the shooter and leads to errors.
    A "Panzerfaust" visor is known in which a mark on a display is mirrored in the beam path of the visor designed as binoculars. The mark is recorded on the display in dependence on a calculated retention and design. The calculation of the retention and design takes place by means of a computer, which is controlled from a gyroscope and a distance meter. The gyroscope thereby misses the distortion of the sight when tracking the target (DE 38 37 922 A1).
    A corresponding arrangement shows DE 36 05 074 C2 for a sight for uncontrolled weapons and EP 0 418 062 BI for a gun sight.
    With this known device, a retention and design are calculated from the target's tracking of the target by means of the sight.
    The invention has for its object to improve the operation of the visor in a weapon system with "intelligent" ammunition.
    According to the invention this object is achieved in that: (a) the image of the search head is connected to image-supplying means, which represent the digital image in optical form, (b) the optically displayed image is projected in the sight.
    Thus, according to the invention, the image captured by the search head is used to improve the operation of the visor. The search head provides an infrared image in the usual way, so that the target can be recognized even in poor visibility and at night.
    It is advantageous if the image has a mark which marks a target recorded by the search head.
    The image processing means thus determine the position of the target from the image captured by the search head for the missile's control function. At this position thus determined, a mark, for example a small window, can be generated in the image display in the visor. The target is therefore easier for the shooter to recognize than if the shooter must recognize the target with the naked eye or only have the image available. Furthermore, the distance to the target can be determined from the relative size of the mark and the image of the target.
    Furthermore, a reservation and design indicating second mark can be projected in the visor. In addition, image processing means may be present, whereby the retention and design for displaying the second mark can be calculated from the movements of the recorded target in the field of view of the search head, the weapon system having a correct retention and design is directed when the second mark is in coverage with the first mark in sight.
    As a result, the shooter does not have to follow the target with the visor in order to determine the retention from the measured movements of the visor. Rather, the search head detects the movements of the target and calculates the line of sight rotation from it. This line of sight rotation determines the search head in any case for the control of the rocket.
    An exemplary embodiment is explained in more detail below with reference to the accompanying drawing.
    FIG. 1 shows a schematic perspective view of a launching tube with a visor for a target ground-to-air missile.
    FIG. 2 schematically shows a rocket with a search head and image processing means, wherein data from the search head and the image processing means can be transferred to a display via a contact-free switching location.
    FIG. 3 shows by way of example the image observed by the shooter in the sight.
    FIG. 4 shows a diagrammatic perspective view of the visor designed as a target binocular with a mirrored display.
    FIG. 1 shows a launch tube 10 for a target ground-to-air missile 12 to be fired by a person (FIG. 2). The launch tube 10 has a handle 14 and a visor 16.
    The rocket 12 has an infrared search head 20, thus acting on heat radiation from the target 18 (Fig. 3). The search head 20 is arranged behind a dome 22, which is permeable to infrared radiation and forms the nose of the rocket 12. The search head 20 has an imaging optical system 24 and a matrix detector 26. The imaging optical system 24 is symbolized by a lens. The matrix detector 26 is a two-dimensional arrangement of detector elements. The imaging optical system generates an infrared or thermal image of a field of view 28 with an infinitely lying object on the matrix detector 26. The object optionally includes a target 18, as shown in Fig. 3. The detector elements of the matrix detector 26 convert the brightness values of the individual pixels (pixels) of the generated image into electrical signals, from which digital brightness finally values are derived. A digital image in the form of a matrix of digital brightness values is thus obtained. This is indicated by a block 30 in FIG.
    The brightness values thus obtained are switched via a contactless switching location 32 to image-supplying means in the form of a display 34. The display 34 is preferably an AMEL, i.e. a matrix of electro-luminescent elements.
    The brightness values are further subjected to image processing such that a target is recognized and located in the field of view. From this image processing the location of the target or the position of the target in the field of view of the search head is thus determined. This is indicated by block 36 in FIG. This is part of the already present function of the rocket. The thus obtained position of the target in the field of view is also switched via the contactless switching location 32 on the display 34 and in such a way that a mark 38 is obtained on the display 34 at the location of the target 18 in the field of vision 28 shown. , for example in the form of a small square window. The mark 38 can be generated so that its color changes when it represents a recorded target.
    The signal processing of the rocket 12 further determines the rotation of the line of sight from the rocket 12 to the target 18 in the inert space. This is indicated by the block 40. This also belongs to the normal function of the rocket. The rotation of the line of sight is switched on the control 42 for proportional navigation. Since the rocket 12 is stationary for firing, the rotation of the line of sight with respect to the shooter and the launching tube 10 is determined in this way. The rotation of the line of sight is again switched via the contactless switching location 32 on a calculating device 44 of the sight 16 for retention and setup. From the rotation of the line of sight, the computing device 44 calculates the retention relative to the location of the target 18 in the field of view 28 recorded at a given moment and provides a retention mark 46 on the display 34 (FIG. 3).
    In Fig. 4 the optics of the visor are shown schematically in perspective.
    A visor house is indicated by 48. The visor housing 48 has a flat rectangular basic shape and is semi-cylindrical on a narrow side running in the longitudinal direction. On the narrow side opposite the semi-cylindrical side, the electronics 50 of the display and the display 34 are located in the visor housing 48. The display 34, as indicated in Fig. 4, has a mark 38 at the location of the image of the goal. The sight 16 has a telescope or binocular tube 52 which is received in a cylindrical mount 54. The other half of the cylindrical mount 54 forms the semi-cylindrical narrow side of the visor housing 48. The telescope 52 has an objective lens 56, a reversing lens 58 and an eyepiece 60. The objective lens 56 provides a realistic image of a the infinite lying object in a first intermediate image plane 62. The reversing lens 58 images the intermediate image plane 62 in a second intermediate image plane 64. In this second intermediate image plane 64 there is a plate 66 with marks to be described. The intermediate image plane 64 is observed through the eyepiece. The intermediate image plane 64 is located in the focal plane of the eyepiece 60 located on the side of the object. Objects such as the marks on the plate 66 in the second intermediate image plane 64 appear before the observer, here the shooter who the visor used, in the infinite and therefore in the perceived object area. In the beam path between the intermediate image plane 64 and the eyepiece 60, a partially transmissive mirror 68 inclined at 45 ° to the optical axis of the system is arranged. The mirror 68 is located in the area of the display 34 and mirrors the display 34 in the beam path of the telescope 52. There is a lens 70 between the display 34 and the mirror 68. The lens 70 provides a virtual image via the mirror 68 of the display 34 in the intermediate image plane 64. Thus, through the eyepiece 60, the display 34 is also seen in infinity.
    FIG. 3 shows the image seen through the eyepiece in the infinite view. The visor 52 sees a relatively large field of view 72. In this field of view 72 one can see infinitely a reticle 74, which indicates the fixed arrow direction of the launch tube 10 and a line 76 running remotely below the reticle with three marks 78, 80 and 82 shown on the line 76. With one of the markers can be covered in the manner described above, the target according to the estimate of the shooter, in order to obtain a somewhat correct hold and design. An ellipse 84 indicates the field of view of the search head 20 of the rocket 12. In this area, a thermal image of the object is mirrored by the display. The target 18 lies in this field of view in FIG. 3. The target 18 is additionally clearly marked by the square window 38. Finally, the display mark 46 also reflects the holding mark 46 in the field of view of the visor. The holding mark 46 is positioned such that the starting tube 10 is in the correct firing position when the target 18 and the holding mark cover each other. Further data can be mirrored in via switch locations via the display 34, for example azimuth and elevation of the target or friend-enemy information.
    The visor described works as follows.
    The launch tube 10 with the rocket and the search head is aimed approximately at the target. This can be done on the basis of instructional information, which is also supplied and mirrored via a switching location and the display 34. When the search head 20 has recorded a target, the mark 38 appears or the mark 38 changes color. The target is therefore clearly marked for the shooter. This also applies to poor visibility or darkness, since the position of the target is derived from the thermal image of the search head. The search head also determines the rotation of the line of sight to the target and the computing device 44 determines therefrom the necessary holding and arrangement of the launching tube 10. Now the holding mark 46 appears. The shooter must now point the launching tube 10 such that the target 18 comes into coverage with the holding mark 46. Then the launching tube 10 is at least substantially aimed at the target. As long as the target is also in the correct range of fire, which can also be indicated via the display 34 on the basis of a range finder signal, the rocket can be fired. conclusions
