Description

The present invention relates to the field of production of military equipment, weapons and defense systems and, in particular, can be used to determine the location of such firing points, such as long-range artillery mounts and mortars.

There is a known problem of the need for accurate, operational and reliable determination of the location of enemy firing points.

A known counter-battery combat method being implemented by the “Radar Station for Counter-Battery Combat” includes the notching of artillery weapons at an early stage of flight, several measurements of the current position of the munition in order to calculate its trajectory. On the basis of its extension and extrapolation of measurements, the location of the fire weapons and the places where their ammunition can be caught are determined. At the same time, for detecting the firing positions of enemy artillery, the radar beam scans the space above the horizon line, forming a detection barrier. Upon receipt of the reflected signal, the station accompanies the target for the time necessary to clarify the trajectory of the projectile and calculate the method of extrapolating the coordinates of the firing position and the place of ammunition fall. In this case, the caliber of the ammunition and the type of the firing gun are automatically determined, the approximate dimensions of the firing position of the enemy’s battery are estimated, and the targets are classified by the degree of their threat, see the website http://warfiles.ru/show-50343-radiolokacionnye-stancii-kontrbatareynoy-borby- osnovnyh-zarubezh nyh-stran.html.

However, the known method and its implementing device are complex both technologically and in control. In addition, the known object is heavy, bulky, which complicates its transportation to the installation site, because requires auxiliary vehicles for its delivery to the work area.

The aim of the present invention is to achieve a technical result to simplify the design of the device that implements the method, facilitate its operation, reduce the cost and ensure transportability of human resources.

The specified technical result for the method is achieved by the fact that in the known method for determining the position of a firing position, including rotation of a radar station, scanning the horizon and subsequent calculations, it is proposed to map the operator to the terrain, to calibrate the image size on a computer monitor with dimensions real environmental objects, such as trees, hills, mountain ledges, set up a video camera and vertically two laser placed on top of each other emitters oriented along the vertical axis, along the horizon and in the sector of the proposed location of the firing points, scanning by laser emitters in the intended scanning sector with the formation of laser planes, while the signals from the video camera are transmitted to the computer monitor, the intersection points of the projectile with the laser planes are fixed, connect the points with a line that is extrapolated to the intersection with the surface of the earth, determine its length, the height of the point of intersection of the projectile with the lower laser d above the ground plane and calculating the distance to the firing point according to the formula:

(one)

Where

K is the distance to the firing point of the firing gun;

h is the height of the point of intersection of the projectile with the lower laser plane formed by the rotating lower laser emitter;

L is the distance from the point of intersection of the projectile with the lower laser plane formed by the rotating lower laser emitter to the firing point.

The technical result for a device that implements a method for determining the location of the firing point of the first embodiment, is achieved by the fact that in a known device that includes an engine and a computer, it is proposed

to install vertically on the axis of rotation of the reversing engine two, one above the other, laser emitters, a camcorder that are azimuthally oriented along the horizon, the camcorder output is proposed to be connected to a computer, while the reversible motor is proposed to be connected to the output of the trigger register, the input of which is connected to an adjustable pulse generator frequency.

The invention is illustrated in graphic materials.

In FIG. 1 shows a structural block diagram of a device that implements the method. In FIG. 2 is a schematic drawing for calculating the location of the firing points.

A device that implements the claimed method for determining the location of the firing point shown in the drawings includes:

1 - reverse engine;

2 - laser emitter;

3 - video camera;

4 - computer;

5 - an adjustable frequency pulse generator;

6 - trigger register;

7 - location of the firing point;

8 - the trajectory of the projectile (mines);

9 - points of intersection of the projectile with the laser plane;

10 - a device for implementing the method of determining the location of the firing points includes objects 1-6.

A device 10 implementing a method for determining the location of enemy firing points, see FIG. 1, consists of a reversing engine 1, on the axis of which are installed two vertically, one above the other, laser emitter 2 and a video camera 3, which are oriented azimuthally along the horizon, the output from the video camera 3 is connected to the computer 4, while the reversing engine 1 is connected to the output trigger register 6, the input of which is connected to a pulse generator 5 of adjustable frequency.

The claimed method for determining the location of the firing position works as follows.

A device with vertically placed on the axis of the reversing engine 1, one above the other, laser emitters 2 and a video camera 3 is installed in the area of the possible appearance of the projectile flight path. On the map, the device is linked to the terrain and the image sizes are calibrated on a computer monitor 4 with the sizes of real environmental objects, for example, trees, hills, mountain ledges. Laser emitters 2 and the video camera 3 are oriented along the horizon. At the beginning of firing from a firing point, a reversible engine 1 is turned on, which scans the flight sector of the projectiles with laser emitters 2. During continuous high-speed scanning of laser emitters 2, laser planes are formed. When fired, a projectile (mine) that has fired from a firing position intersects the lower and then the upper laser planes in turn, which manifests itself in the form of two flares 9, which are fixed as bright points on the computer monitor 4. These points are connected by a line, which, here, on the monitor computer 4 is extrapolated to the intersection with the surface of the earth, and then determine its position on the map. Thus, the direction of the possible location of the firing point is determined. But the firing point can be located in the forest, in the ravine and to determine its exact position, additional calculations are performed:

- the height h of the point of intersection of the projectile with the lower laser plane formed by the lower laser emitter,

- the distance L from the point of intersection of the projectile (mines) with the laser plane formed by the scanning lower laser emitter to the firing point.

After that, calculations are carried out to the location of the firing point according to the formula (1) according to the diagram, see FIG. 2.

Where

K is the distance to the firing point of the firing gun;

h is the height of the point of intersection of the projectile with the lower laser plane formed by the lower laser emitter;

L is the distance from the point of intersection of the projectile (mines) with the lower laser plane formed by the scanning lower laser emitter to the firing point.

Thus, the claimed method and the device implementing it provide an accurate and efficient determination of the location of the firing point. At the same time, the device that implements the claimed method is easy to carry by two specialists and easy to operate.

The claimed invention is new, previously unknown anywhere, which indicates its compliance with the patentability criterion - novelty.

The claimed invention can be manufactured at any instrument-making or radio engineering enterprise of medium degree of technological equipment, which indicates its compliance with the patentability criterion - industrial applicability.
