Description

The invention relates to the field of fire and artillery fire control.

The closest to the proposed one is a method of firing at areal targets (see “Rules for firing and controlling artillery fire (PSiUO-96), put into effect by order of the Commander-in-Chief of the Ground Forces of 12/19/97, No. 208. Part 1, 1998 Articles 190, 191). In this method, the battery can fire on three installations of the sight and on one or two settings of the protractor only along a conditional rectangle. At two installations of the protractor, firing is conducted if the interval of the fan exceeds 25 meters when hitting hidden and armored targets and 50 meters - open unarmored targets. When shooting to defeat group or individual targets with a battery, a jump in the sight or a scale value equal to 1/3 of the target depth with rounding up to whole divisions of the sight is assigned; fan interval equal to the front width of the target divided by the number of guns in the battery.

The disadvantages of this method is that it does not take into account the configuration of areal targets, does not determine the rational number of aiming points for each gun of the battery involved in firing. Ammunition consumption during shelling in this way is overpriced.

Closest to the device according to this invention is an automated control system for guidance and fire of a combat vehicle of a multiple launch rocket system (RF patent No. 2167380). For its work, an autonomous topographic and geodetic reference and orientation of the combat vehicle, autonomous calculation of firing settings and flight task data according to the coordinates of aiming points, and aimless guidance of the guide package are used. The autonomous orientation system determines the initial azimuth, and navigation equipment determines the initial coordinates of the combat vehicle. After that, the navigation system continuously determines the location and orientation of the combat vehicle displayed by the system against the background of the topographic map. After receiving target designation through the data receiving and transmitting unit, the system also displays the distance to the target and the direction of arrival to the starting position. At the starting position, the system determines the set guidance angles for the current coordinates of the combat vehicle. The system continuously detects mismatches with current pointing angles. Guidance drives for these mismatches are carried out by pointing the guide package. The disadvantage of this system is its complexity, high cost, limited use.

The objective of the invention is at relatively low cost to increase the efficiency of shooting, combat potential of artillery firing units.

The technical result of the invention is to reduce the consumption of ammunition for hitting targets, increasing the density of shelling targets without increasing the number of involved guns.

In addition, the equipment for implementing the method allows you to accurately determine the coordinates of targets on the fired area without the use of unmasking battle factors, and also allows you to connect all the guns and battery control points into a single network, knowing at any time the exact location of each gun in relation to the target, which also dramatically increases the effectiveness of shooting due to the strict restriction towards the maximum possible reduction of the fired area and a more accurate binding of each gun not generally to the fired area, but to a specific element of the goal.

The technical result is achieved by the fact that in the method of firing at the areal target, aiming points for the guns of the battery are determined and fire is fired at the target, while the position and nature of the target elements are preliminarily evaluated, then the exact contour of the areal target is determined in the form of an arbitrary polygon in accordance with the data obtained, the number and position of aiming points depending on the type of the polygon, the number of guns in the battery, the nature of the target, ballistic shooting conditions.

In the specified method, the determination of the exact contour of the areal target is made from a triangular to hexagonal polygon.

The technical result is also achieved by the fact that the device for firing at the area target contains navigation equipment, a system for determining the coordinates of the target, connected to the control and computing device, transceivers. The difference between the device is that it contains n constituent units of sets of observers, connected to the network through the base complex, each unit set of the observer additionally contains a device for visualizing the coordinates of the targets connected to the control and computing device, and the transceiver is connected to the control and computing device of the single set an observer and a group device for connecting to the radio channels of the base complex. The basic complex also contains a coordination and control device connected to its input and output, respectively, with the output and input of the group device for connecting to radio channels and, in addition, connected to the input of the visualization device on digital circuits of target weapons and the output of a memory block containing a distortion matrix, and also connected to the input and output of the memory block containing digital circuits, plans, maps of the area to be shelled.

Thus, with the known location of the target elements in the area, select the corresponding polygon, for example a triangle, into which the target elements clearly fit, determine the position of the three base aiming points, then determine the position of three additional aiming points and conduct additional analysis on the possibility of combining the aiming points and thereby reducing the number of installations of the sight-goniometer for guns. Then, based on the final list of aiming points, the aiming points of each gun are determined. As a result, the density of shelling the target is increased by at least 30% with the same number of guns and ammunition.

In addition, if necessary, in the case of determining the coordinates of the targets, it becomes possible not to use the laser range finder unmasking the observer, as well as to use fragments of the terrain in digital form without precise reference and preservation of proportions in the distances and sizes of objects and without displaying all objects of the fired place, which is often not required, thanks to which it is possible to quickly solve the problem of tracking the exact location at each time of the means of destruction of targets, in this case, guns, including and their movement on digital compact mnemonic diagrams with display directly on the display screen.

In Fig.1-a, 1-b, 1-c, 1-d, all used polygons are shown with the base and additional aiming points affixed to them, depending on the location of the target elements, which are shown by small rectangles in the drawings.

Figure 2 shows a block diagram of a device for firing at an area target in terms of coordinating target weapons, accurately and covertly detecting the latter, as well as visualizing weapons on digital circuits.

The fire control device for artillery batteries is network-based and by combining the appropriate observer systems for a single gun or individual batteries, it is possible to accurately and discreetly determine the coordinates of each target on the area to be fired, as well as create a matrix that is simplified using a distortion matrix or transforms a digital image of targets on a digital circuit the overall picture (display) of all means of destruction of targets of the shelled area. If we take into account that the position of each gun is precisely determined at each moment of firing using the space navigation system consumer (NAP KNS) included in the complex of navigation equipment and the proposed approach for the polygonal allocation of the area on which all targets are located, the number of installations of the ranging complex is reduced, determined optimal location of aiming points for each gun, the movement of each gun is visually controlled. Moreover, the device is preferable to the use of non-laser rangefinders, and digital terrain schemes, which allows you to do without unmasking radiating equipment.

The fire control device contains networked single sets of observer 1. Each set 1 includes a system for determining the coordinates of target 2, containing a ranging and goniometric equipment, in particular, a sighting device together with a vertical detection device, an automatic azimuth acquisition device, an automatic elevation-taking device as well as a laser rangefinder. Instead of a laser rangefinder, digital circuits, plans, maps that are stored in the corresponding memory blocks can be used. The device for determining the coordinates of the target 2 is connected to the control device and computing 3, which receives the corresponding target data. As the device 3, the corresponding microprocessor can be used. The kit 1 also includes a device for determining the observer's own coordinates in the form of a user's navigation equipment (NAP KNS) 4, as well as a device 2 connected to a control and computing device 3, which is connected to a target coordinate visualization device 5, as well as to a transceiver 6 The transceiver 6 of each set of observer 1 is connected to a group device for connecting to the radio channels 7 of the base part of the network complex for controlling the firing of an area target. This basic part of the complex also includes a coordination and control device 8 connected to a group device for connecting to radio channels 7, made in the form of a server-type processor, to which a memory unit 9 is connected, containing mimic diagrams, plans and digital maps of the area. A memory block 10 is connected to the input of the coordination and control device 8, which contains a distortion matrix or a matrix transforming a digital image, which allows using the coordination and control device 8 to convert points on a digital area map to corresponding points on a mnemonic diagram or plan, if necessary in a particular case , for example, with significant remote separation of guns or batteries. The visualization of objects, in this case guns, on digital circuits, including the fixation of their movements, is carried out in device 11.

Scanning of the terrain is carried out using some or other image receiving devices, for example optical (not shown in the drawing).

When shelling targets of arbitrary configuration, the selection of these polygonal figures is determined by the prevailing conditions of the combat situation in terms of the location of target elements on the terrain, their concealment and their nature (armored, unarmored objects). Next, determine the center of the target and the main points of aiming the figure, in particular, for a triangle, these will be the midpoints of the center-vertex segments (3rd point), as well as the midpoints of the center-center segments of the side of the triangle (3rd point); for a quadrangle, the midpoints of the center-vertex segments (4th points), as well as the midpoints of the center-center segments of the 2 largest sides of the quadrangle (2nd points); for a pentagon - the middle of the center-vertex segments (5 points), as well as the center of the figure (one point); for a hexagon, the middle of the center-vertex segments (6 points). After that, the distance between the points is determined and, if it is less than 25 meters for concealed and armored targets or less than 50 meters for openly located targets, these points are combined, that is, irrational points are excluded, but in any case from 3 to 6 aiming points are left. Around the obtained basic aiming points, aiming points are formed for each weapon depending on the size of the target, the dispersion of shells for the available removal to achieve a uniform target shelling density.

For the operation of the fire control device of artillery batteries, in the case of using a distortion matrix, certain preparatory work is carried out, namely, the digital mimic is combined with a digital accurate map of the area, for example, according to a special algorithm, resulting in a matrix or distortion matrix transforming the digital image. The distortion matrix is stored in block 10. The distortion matrix allows using the appropriate processor, for example, the processor of the coordination and control device 9, to convert points on the map of the area into corresponding points on the mimic diagram. This allows not only on the map, but also on the mimic diagram, which often greatly simplifies the work, to track the position of each weapon, as well as its movement with the corresponding visualization in the device 11, if necessary.

The coordinates of the targets of the fired area are determined using device 2. Data from it and the device for determining the own coordinates of the observer 4 are sent to the control and computing device 3, and from it, after appropriate processing, to the device for visualizing the coordinates of the targets 5 and to the transceiver 6, and then through the group device connecting to the radio channels 7 to the coordination and control device 8. The device 8 also receives data from other individual sets of observers, as well as data on plans, mnemonic diagrams and maps about the area being shot from block 9. The data processed by the device 8 is visualized in the object visualization device, in this case, targets 11.
