Description

The invention relates to the field of control and regulation, in particular to guided weapons.

To defeat targets with anti-tank weapons, a number of guidance methods are known. The guidance method described in the book of Lebedev V.Ya. "Directory of ground artillery officer." - M .: Military Publishing House, 1977. - P.68, consists in conducting a topographic and geodetic reference of the unit commander and firing unit and selecting landmarks for determining the coordinates and heights of firing positions, for determining directional angles of oriented directions and for guiding weapons in a given direction. Next, reconnaissance and determination of the coordinates of targets is carried out using rangefinders and radar stations. The coordinates of the goals are put on a paper map; they calculate the oriented direction for the operator and transmit the direction of fire and the distance to the target to the operator. The implementation of this guidance method requires considerable time.

A known method of targeting the anti-tank missile system "Cornet-E" [Stepanichev IV, Zakharov LG, Soloviev N.V. ATGM “Cornet-E” changes the appearance and capabilities of weapons // Horizons KBP. - 2007. - No. 3. - S.17-21]. The commander’s reconnaissance and surveillance equipment and the operator’s weapons are mounted on the same chassis. The direct guidance of weapons to the target consists in jointly orienting the reconnaissance means of the commander and the operator’s armament, detecting and tracking the target with the commander using reconnaissance and surveillance means, transferring the command to aim at the operator, aiming the weapon at the target by the operator, and hitting the target with the operator out of arms. The disadvantage of this guidance method is the impossibility of simultaneous and parallel guidance by the reconnaissance and shooting control operator. So, when a target is detected, the commander or he himself strikes, or transmits the target designation to the operator. In this case, the commander does not conduct reconnaissance during the defeat of the target due to the placement of fixed reconnaissance assets at the operator’s place.

The task of expanding the capabilities of weapons, improving accuracy, reducing the time of target designation and direct guidance was solved in the method of direct aiming of weapons at a target selected as a prototype [Russian Patent No. 2204783 C2, cl. F41G 3/00, 7/00, 2000. The method of direct aiming of weapons at a target and device for its implementation].

The method of direct guidance of weapons to the target at arbitrary placement of the commander and operator on the ground includes the joint orientation of the commander’s reconnaissance means and the operator’s armament on the ground relative to geographical coordinates, target detection and tracking by the commander using reconnaissance and surveillance tools, entering target coordinates into the commander’s control panel, selection targets and transmission of the targeting command and target coordinates from the commander’s control panel to the operator’s control panel by digital radio communication, targeting weapons to the target in two phases, with the first targeting of weapons is carried out with the remote operator control on joint benchmarks, then the deviations from the target center of weapons sights, defeat the purpose of the weapons operator.

Direct guidance of weapons on target by the proposed method is as follows. The commander and crews occupy command and observation and firing positions, respectively, carry out geo-referencing and orientate reconnaissance and weapons in the main direction of fire. At the same time, the location coordinates of all operator panels subordinate to the commander are entered into the commander’s control panel. The display of the commander’s control panel displays all the calculations that obey the commander. When a target is detected, the coordinates of the target from reconnaissance equipment are automatically sent to the commander’s control panel; the symbol on the display of the control panel indicates the type of target, the number of the target and its coordinates. Using the function keys, the commander selects one of the subordinate calculations and gives the order to the appropriate operator to destroy the target. The coordinates of the target are transmitted to the control panel of the corresponding operator in the geographical coordinate system, and the symbol of the target corresponding to the type of target, its coordinates, direction to the target are automatically displayed in accordance with the received coordinates on the operator’s display. The coordinates of the target are displayed in a geographical coordinate system or in the form of an azimuth and distance to the target relative to the operator’s control panel. The operator deploys weapons in the direction of the target and, after capturing the target, destroys it.

The disadvantage of the prototype is the inability to shoot at a moving target in motion.

The objective of the invention is to reduce the time of direct guidance when firing at a moving target, ensuring the defeat of the moving target in motion, increasing the survival of the unit in combat conditions.

This task is carried out due to the fact that in the known method of direct pointing weapons at a target with arbitrary placement of the commander and operator on the ground, including orienting the reconnaissance means of the commander and arming the operator on the ground with respect to geographical coordinates, detecting and tracking the target with the commander using reconnaissance and surveillance means , entering the coordinates of the target into the commander’s control panel, selecting the target and transmitting the targeting command and coordinates of the target from the commander’s control panel to the control panel of the operator’s digital radio communications, aiming weapons at the target in two stages, first from the operator’s control panel, then by deviating the target from the center of sight of the weapon, hitting the target with the operator from the weapon, the new thing is that the deployment of reconnaissance and surveillance means of the operator’s commander and weapons the terrain is carried out on two chassis, respectively, with the ability to direct weapons in motion, in the commander’s control panel and the operator’s control panel, a single computer time is set, orientation reconnaissance means of the commander and the operator’s armament on the ground and in the movement are carried out using navigation means, and the coordinates of the target’s location in the geographic coordinate system, the speed of movement and the time of measuring the target’s coordinates are transmitted periodically from the commander’s control panel to the operator’s control panel, until the weapon is aimed at the operator’s control panel determines the coordinates of the predicted target location point by the time the weapon sighting is aimed at the target, taking into account the target’s speed and remescheny chassis and initially aim the weapons on the predicted point finding purposes.

Direct guidance of weapons on target by the proposed method is as follows. The commander’s reconnaissance and surveillance equipment and operator’s weapons are installed on two chassis, respectively. Shooting is conducted at arbitrary placement of the commander and operator on the ground and in motion. When preparing for battle, a single computer time is set in the commander’s control panel and the operator’s control panel. Upon detection of the target, the coordinates of the target from reconnaissance equipment automatically or at the command of the commander, enter the commander’s control panel; after that, the symbol indicating the type of target, the number of the target and its coordinates is displayed on the display of the commander’s control panel. The display of the commander’s control panel displays the positions of all chassis with weapons (weapon systems) that obey the commander. The location coordinates of all weapon systems reporting to the commander are determined using the navigation equipment of each weapon complex, then they automatically enter the operator’s control panel of the corresponding weapon complex and are automatically transmitted to the commander’s control panel via digital radio communication. Orientation of the reconnaissance equipment of the commander and the armament of the operator on the ground and in the movement is carried out using navigation aids. Using the function keys, the commander selects one of the subordinate weapon systems and issues an order to the appropriate operator to destroy the target. Target coordinates in the form of target coordinates in a geographical coordinate system, speed and time of measuring target coordinates are transmitted periodically via digital radio communication from the commander’s control panel to the operator’s control panel. In the operator’s control panel, the coordinates of the predicted target location point are determined by the time the weapon’s sight is aimed at the target, taking into account the target’s speed and chassis movements. The symbol of the target corresponding to the type of target, its coordinates, direction to the target is automatically displayed on the operator’s control panel display. The coordinates of the target are displayed in a geographical coordinate system or in the form of an azimuth and distance to the target relative to the operator’s control panel. The operator deploys weapons in the direction of the target in two stages. In this case, the operator first aims the weapons at the predicted target location, then targets the deviations of the target from the center of sight of the weapons and after capturing the target destroys it.

In the particular case, in order to identify preferred ratios for reducing target designation time and direct weapon guidance and improving the accuracy of weapon guidance when firing at a moving target in motion, in the development of the proposed method, a method has been developed for direct aiming of weapons at a target when transferring target coordinates, target speed and the time of measuring the coordinates of the target is carried out by radio communication with a frequency of 0.2-5 Hz, the measurement of navigation parameters is carried out with a frequency of 25-200 Hz.

Direct guidance of weapons on target by the proposed method is as follows. Upon detection of the target, the coordinates of the target from reconnaissance equipment automatically or at the command of the commander, enter the commander’s control panel; after that, the symbol indicating the type of target, the number of the target and its coordinates is displayed on the display of the commander’s control panel. The display of the commander’s control panel displays the positions of all chassis with weapons (weapon systems) that obey the commander. The location coordinates of all weapon systems reporting to the commander are determined using the navigation equipment of each weapon complex, then they automatically enter the operator’s control panel of the corresponding weapon complex and are automatically transmitted to the commander’s control panel via digital radio communication. Orientation of the reconnaissance equipment of the commander and the armament of the operator on the ground and in the movement is carried out using navigation aids. At the same time, navigation parameters are measured at a frequency of 25-200 Hz. Using the function keys, the commander selects one of the subordinate weapon systems and issues an order to the appropriate operator to destroy the target. Target coordinates in the form of target coordinates in a geographical coordinate system, speed and time of measuring target coordinates are transmitted digitally with a frequency of 0.2-5 Hz from the commander’s control panel to the operator’s control panel. In the operator’s control panel, the coordinates of the predicted target location point are determined by the time the weapon’s sight is aimed at the target, taking into account the target’s speed and chassis movements. The symbol of the target corresponding to the type of target, its coordinates, direction to the target is automatically displayed on the operator’s control panel display. The coordinates of the target are displayed in a geographical coordinate system or in the form of an azimuth and distance to the target relative to the operator’s control panel. The operator deploys weapons in the direction of the target in two stages. In this case, the operator first aims the weapons at the predicted target location, then targets the deviations of the target from the center of sight of the weapons and after capturing the target destroys it.

In the particular case, in order to identify the preferred relationship in the development of the proposed method, a method for direct guidance of weapons to the target is developed, when the coordinates of the predicted target location are determined by the following relationship:

$$\begin{array}{l}\\ \left(\begin{array}{c}{x}_t\\ y_t\\ z_t\end{array}\right)=\left(\begin{array}{c}{x}_0\\ y_0\\ z_0\end{array}\right)+\left(\begin{array}{c}{V}_x\\ V_y\\ V_z\end{array}\right)\cdot \Delta t,\left(\mathrm{one}\right)\\ \end{array}$$

where x _t , y _t , z _t are the coordinates of the predicted target location in the stabilized coordinate system at the time of completion of the first stage of guidance of weapons t,

x ₀ , y ₀ , z ₀ - coordinates of the target location point in the stabilized coordinate system at the time of measuring the target coordinates t ₀ ,

V _x , V _y , V _z - the speed of the target,

Δt is the time of the target’s movement from the moment of measuring the target’s coordinates to the completion of the first stage of weapon guidance, which is determined by the ratio

$$\Delta t=(t_{te\mathrm{to}\mathrm{at}u.}-t_0)+\Delta t_{n\mathrm{but}\mathrm{at}ed.},\left(2\right)$$

where t is _current. - the current time to turn weapons on target,

t ₀ - time measurement of the coordinates of the target,

Δt _hover - the time of pointing weapons at the target from the current moment until the completion of the first stage of pointing weapons; moreover, Δt _induced. taken equal to 0.1-5, taking into account the magnitude of the turn of arms.

Direct guidance of weapons on target by the proposed method is as follows. Upon detection of the target, the coordinates of the target from reconnaissance equipment automatically or at the command of the commander, enter the commander’s control panel; after that, the symbol indicating the type of target, the number of the target and its coordinates is displayed on the display of the commander’s control panel. On the display of the commander’s control panel, the positions of all weapon systems subordinate to the commander are displayed. The location coordinates of all weapon systems reporting to the commander are determined using the navigation equipment of each weapon complex, then they automatically enter the operator’s control panel of the corresponding weapon complex and are automatically transmitted to the commander’s control panel via digital radio communication. Orientation of the reconnaissance equipment of the commander and the armament of the operator on the ground and in the movement is carried out using navigation aids. Using the function keys, the commander selects one of the subordinate weapon systems and issues an order to the appropriate operator to destroy the target. Target coordinates in the form of target coordinates in a geographical coordinate system, speed and time of measuring target coordinates are transmitted periodically via digital radio communication from the commander’s control panel to the operator’s control panel. In the operator’s control panel, the coordinates of the predicted target location point are determined by the time the weapon visor is aimed at the target according to dependence (1). The symbol of the target corresponding to the type of target, its coordinates, direction to the target is automatically displayed on the operator’s control panel display. The coordinates of the target are displayed in a geographical coordinate system or in the form of an azimuth and distance to the target relative to the operator’s control panel. The operator deploys weapons in the direction of the target in two stages. In this case, the operator first aims the weapons at the predicted target location, then targets the deviations of the target from the center of sight of the weapons and after capturing the target destroys it.

To implement the described methods can be applied to the device used in the prototype. As the commander’s control panel and the operator’s control panel, a computer system of the “Commander’s panel” type [TECA.466225.050 TU], developed by STC ELINS CJSC, Moscow, Zelenograd, can be used. As digital radio stations through which the radio network is built, the “Access Modules Set” [VAYAP1.110.167 TU] developed by the State Unitary Enterprise SPC “SPURT”, Moscow, Zelenograd, can be used. As reconnaissance means, the Fara-1 radar station [AVIM.461412.006-01 TU] developed by OAO Strela OJSC, Tula, can be used.

As means of navigation, the strap-down inertial navigation system of topographic location and navigation BINS-TP [IGAR.401233.202-05 TU], developed by ZAO NPK ELECTROOPTIKA, Moscow, can be used. As the chassis can be used chassis BMP-3 [Suvorov S.V. "BMP-1, BMP-2 and BMP-3 infantry fighting vehicles." - M .: Strategy KM: Yauza: Eksmo, 2011. - P.86-113].

The proposed group of inventions gives a qualitative result in comparison with the prototype. Using the proposed group of inventions will reduce the time of direct guidance when firing at a moving target, when reconnaissance equipment and weapons are in motion, will increase the survival of the unit and, therefore, increase the effectiveness of firing anti-tank and other weapon systems.
