Description

The utility model relates to the field of military equipment and can be used in the design of short-range anti-aircraft installations with artillery weapons.

Known radar-instrument complex anti-aircraft self-propelled gun ZSU-23-4M "Shilka") [1, 2].

The radar-instrument complex includes: a target tracking radar, a calculating and solving device, a first, second and third summation device, a coordinate coordinate converter, a gun coordinate converter, a gyroazimuth horizon, an antenna, an optical sight, a horizontal guidance hydraulic drive, a vertical guidance hydraulic drive, a shoulder strap towers, anti-aircraft guns, double sight.

Known radar instrument complex operates as follows.

Search, detection, capture and automatic tracking of the target are carried out using a radar tracking target, which automatically accompanies the target in angular coordinates and range. In the process of automatic tracking of the target, the radar station determines the current values of the coordinates of the target, which are received in the computing device. A voltage proportional to the heading angle enters the tracking system of the computer from the gyro-azimuth horizon. In the calculating and decisive device for solving the problem of meeting the projectile with a moving target, the coordinates of the lead point are determined, which, like the signals from the gyro azimuth horizon, the pitching angles that occur when the anti-aircraft self-propelled gun moves are input signals for the gun coordinate converter. The pitch angle values are also used to stabilize the line of sight of the shot.

In the known radar-instrument complex, an indirect stabilization system is used, which provides spatial stabilization of the electric axis of the antenna, the optical axis of the sight, and the axes of the channels of the tables of automatic machines by turning the antenna and automatic machines at angles that compensate for pitching and yaw arising from the movement of self-propelled anti-aircraft guns.

Based on the values of the coordinates of the anticipated point and the angles of quality received in the gun coordinate converter, the full angles of guidance of the anti-aircraft guns are calculated. The values of the full guidance angles go to the inputs of the hydraulic power drives of vertical and horizontal guidance, which ensure the guidance of anti-aircraft machines at a predefined point when rolling and yawing anti-aircraft self-propelled guns.

However, the radar-instrument complex of the product is characterized by significant angular systematic errors in the guidance of anti-aircraft guns and line of sight. This is explained by a large number of mechanical connections, characterized by the presence of inconsistencies, backlashes, and also by the fact that the apparatus for generating the full angles of guidance of the anti-aircraft guns and corrections for stabilizing the line of sight and shot (calculating and resolving device, sighting coordinate transducer, gun coordinate transducer) is made analog principle. The stability of the output signals of this equipment largely depends on the difference in ambient temperature, heating of the equipment during operation and operating time. As a result, the probability of hitting a target is sharply reduced, which is mainly determined by the angular errors of the radar-instrument complex.

The second serious drawback of this radar-instrument complex is the lack of interfacing with higher command posts to ensure operational control and target designation when working as part of a battery of anti-aircraft self-propelled guns.

The closest in technical essence to the claimed is a radar-instrument complex anti-aircraft self-propelled guns according to patent RU No. 65198.

The well-known radar-instrument complex (RPK) contains a radar station (radar) for target tracking, a gyro azimuth horizon, a summing device, an antenna, an optical sight, a horizontal hydraulic actuator, a vertical hydraulic actuator, epaulettes of a turret, anti-aircraft guns, a backup target, an external digital targeting station and computing system.

This PKK operates as follows. The radar emits sounding signals and receives echoes reflected from the target through the antenna. The solution to the problem of meeting a projectile with a task is assigned to a digital computer system. The input signals of the digital computing system, which are used to calculate the trajectory of the target, are signals received from the radar, as well as signals received from the gyro-azimuth horizon.

As a result of processing this data, the digital computing system calculates:

- information about the stabilization of the line of sight coming into the radar;

- the values of the angles to ensure the guidance of anti-aircraft guns and the sight-understudy in the anticipated point.

In the external target designation mode, the signal from the higher command post is received by the radio station and enters the digital computer system, which forms the target designation label and transmits it to the radar. The operator, observing the mark of external target designation on the radar indicator, captures the target for radar auto tracking.

However, the prototype has the following disadvantage. In the well-known PKK there is no possibility of determining the relative position of the combat assets of the complex, which greatly complicates the automated reception of external target designation signals from higher command posts and control and reconnaissance points.

The objective of the utility model is to provide solutions to topographic location problems and the ability to determine the relative position of the combat vehicle and a higher command post, which will allow more efficient control of the complex as a whole and receive external target designation signals from higher command posts in an automated mode.

The first output of the coordinator 16 is connected to the input of the indicator device 17, and the second output is the output of the navigation equipment 13 and connected to the eighth input of the DAC 12.

Mechanical ntenny SE HV output 7 is connected in parallel with the mechanical input antiaircraft machine 9 and 10. The sight-doubler mechanical sensor Mechanical speed input 15 connected to a combat vehicle chassis and a mechanical input of the navigation apparatus 13.

The radar-instrument complex of a combat vehicle operates as follows.

During the operation of the combat vehicle, search, detection, capture and automatic tracking of the target is carried out using radar 1. Radar 1 automatically accompanies the target in angular coordinates (ε is the current elevation angle, β is the current azimuth) and in range D. In the process of automatic tracking of the radar target determines the current values of ε, β and D. Radar 1 emits sounding signals and receives echo signals reflected from the target through the antenna 4.

The task of arms control is to continuously determine the data for firing from the current coordinates of the target and the parameters of its movement, which ensure that the projectile meets the moving target. The basis for solving this problem is the hypothesis of a rectilinear and uniform movement of the target in any plane for a proactive time. The solution to the problem of meeting the projectile with the responsibility of CVS 12.

The input signals of the DAC 12 used to calculate the trajectory of the target are: the current elevation angle of the target ε, the current azimuth of the target β and the current slant range to the target D, received from the radar; as well as signals coming from GAG 2: course angle K, measured from the oriented direction to the projection of the longitudinal axis of the ZSU on a horizontal plane; galloping angle Ψ, measured from the horizontal plane to the longitudinal axis of the ZSU; the trampling angle Q _k, measured from the horizontal plane to the transverse axis of the ZSU. The change in the position of its longitudinal axis in azimuth with respect to the oriented direction that occurs during the movement of the ZSU is called the “yaw” of the ZSU and is also characterized by the course angle K.

The values of K, Ψ and Q _k are used to stabilize the lines of sight and shot. The RPK adopted an indirect stabilization system that provides spatial stabilization of the electrical axis of the antenna and the axes of the channels of the barrel of the machine by turning the antenna and the machine at angles that compensate for pitching and yaw arising from the movement of the ZSU. Since the GAG 2 and antenna 4 are installed in a rotating tower, a break-in system is provided to ensure independence of the oriented direction specified by the GAG and the line of sight from the rotation of the tower. Due to this break-in, when the shoulder strap of the tower 6 is turned to a certain angle, the GAG 2 and the antenna 4 are rotated by the same angle in the opposite direction, remaining stationary relative to the ZSU, which ensures stabilization of the line of sight.

As a result of processing this data, the DAC 12 calculates:

- information about the stabilization of the line of sight entering the radar 1;

- the values of the angles Q and F to ensure the guidance of anti-aircraft guns 9 and the sight-understudy 10 in the lead point, where:

- Q - the full angle of horizontal guidance, measured from the longitudinal axis of the ZSU to the projection of the line of the shot on the plane of the shoulder strap of the ZSU;

- Ф - the full angle of vertical guidance, measured from the plane of the ZSU shoulder strap to the line of the shot.

1 generates radar antenna position control optical sight 4 and 5 signals with the incoming data on the stabilization of the line of sight from the PCV 12. Thus, the control signal ε _ns elevation fed directly to the antenna 4 and 5. The optical sight signal q _ns azimuth pre enters the summation device 3, where it is added (or subtracted) with the current tower pointing angle Q. The control signal β _ns thus generated in azimuth also arrives at antenna 4 and the optical sight 5.

In the external target designation mode, the signal from the higher command point is received by the radio station 11, which provides the reception of code information, and enters the DAC 12. DAC 12 generates a target designation mark and transmits it to the radar 1. The operator, observing the external target designation mark on the radar indicator, captures the target on auto tracking radar.

The task of determining the location of the combat vehicle on the terrain is assigned to the navigation equipment 13. Information about the distance traveled is received from the chassis of the anti-aircraft self-propelled gun (not shown) and, through a flexible roller, is fed to a mechanical speed sensor 15, where it is converted into an electrical signal that carries information about the increment of the path and his sign. Information about the change in the directional angle of the longitudinal axis of the anti-aircraft self-propelled gun is generated in the gyro pointer 14. The coordinator 16, based on the signals of the mechanical speed sensor 15 and the gyro pointer 14, generates the coordinates of a moving object - a combat vehicle. Information about the coordinates of the object is sent to the indicator device 17, as well as to the eighth input of the DAC 12 to ensure the calculation of the relative position of the combat vehicle and a higher command post.

The proposed radar-instrument complex of the combat vehicle is implemented in a new modification of the anti-aircraft self-propelled gun ZSU-23-4M4 (product 2A6M4 "Shilka-M4"). Currently, the 2A6M4 product has successfully passed preliminary (factory) tests. According to the test results, the proposed radar-instrument complex as part of an anti-aircraft self-propelled gun during joint tests with a higher command post of the type ППРУ-М1 (mobile reconnaissance and command post) showed stable operation for receiving and issuing target designation at different relative positions of the air defense system and the air defense system on the ground. Currently, the issue of adopting the ZSU-23-4M4 in the arsenal of the Russian Army is currently being decided.
