AIR THREATS DETERMINING APPARATUS AND COMBINED ENGAGEMENT CONTROL SYSTEM INCLUDING THE SAME

The present invention relates to an air threat determination device and a complex engagement control system having the same, and more particularly, to an air threat determination device capable of judging and responding to the types of targets detected in the air, and a complex engagement control system having the same will be.

In general, a complex engagement control system can fire an interceptor missile by detecting and tracking the missile or shell fired by the enemy. In other words, when the predicted drop point of a missile or shell fired by the enemy is predicted and the predicted drop point overlaps the defense area of the complex engagement control system, the interceptor missile is fired from the ground missile launcher to intercept the missile or shell fired by the enemy. can do.

At this time, the complex engagement control system is separately equipped with a ballistic missile intercepting missile that intercepts weapons of mass destruction such as ballistic missiles and a long-range artillery intercepting missile that intercepts weapons that are fired in large quantities at the same time such as long-range artillery shells. It is difficult to intercept a ballistic missile with a long-range artillery interceptor missile, and intercepting a low-cost long-range artillery projectile with a relatively expensive ballistic missile interceptor missile creates a cost problem. Therefore, when intercepting a ballistic missile launched by the enemy with a ballistic missile intercepting missile and intercepting a long-range artillery projectile with a long-range artillery projectile intercepting missile, the complex engagement control system can be effectively operated.

However, in the prior art, it was not possible to determine the type of projectile fired by the enemy and select a response method according to the type of projectile. Accordingly, since the interceptor missile cannot be selected according to the type of projectile launched by the enemy, a problem may occur that the complex engagement control system cannot properly respond to the projectile launched by the enemy.

Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but will be implemented in various different forms, and only these embodiments allow the disclosure of the present invention to be complete, and the scope of the invention to those of ordinary skill in the art will be completely It is provided to inform you. In order to explain the invention in detail, the drawings may be exaggerated, and like numerals refer to like elements in the drawings.

1 is a diagram showing the structure of a complex engagement control system according to an embodiment of the present invention, FIG. 2 is a diagram showing the structure of an air threat determination device according to an embodiment of the present invention, and FIG. 3 is an embodiment of the present invention It is a diagram showing a structure in which a first evaluation unit, a second evaluation unit, and a target alignment unit are provided in the air threat determination device according to Hereinafter, a complex engagement control system according to an embodiment of the present invention will be described.

The complex engagement control system according to an embodiment of the present invention is a complex engagement control system for protecting facilities on the ground from air threats. Referring to FIG. 1 , the complex engagement control system 100 includes a first launch device 110 , a second launch device 120 , an air threat determination device 130 , and an engagement control device 140 .

In this case, the air threat may include a first air threat and a second air threat having a lower risk than the first air threat. For example, the first air threat may be a ballistic missile, and the second air threat may be a long-range artillery projectile. Since ballistic missiles can carry nuclear warheads or chemical and biological weapons, they have a higher risk than long-range artillery shells. However, the types of air threats are not limited thereto and may vary.

The first launch device 110 may be a weapon system that launches a first intercepting projectile that intercepts a first air threat. A plurality of first launch devices 110 may be provided to defend different defense targets (eg, areas or buildings to be defended). In addition, the first launch device 110 may fire the first interceptor projectile in multiple layers. For example, the first launcher 110 fires the first intercepting projectile at a relatively high altitude and fires the first intercepting projectile at a lower altitude than the upper launcher with a wider firing range, and the lower lower level at which the first intercepting projectile is fired than the upper launcher. It may include a launcher. Accordingly, the first intercepting projectile fired from the upper launcher may intercept the first air threat at a high altitude, or the second intercepting projectile fired from the lower launcher may intercept the first air threat at a low altitude.

The second launch device 120 may be a weapon system that fires a second intercepting projectile that intercepts a second aerial threat having a lower risk than the first aerial threat. For example, the second launch device 120 may include a plurality of launchers arranged to defend the same single defense target. Accordingly, even if a plurality of second air threats are launched into the defense area of the second launch device, it is possible to intercept the second air threats by firing a plurality of second intercepting projectiles.

The engagement control device 140 may be connected to send and receive signals to and from the air threat determination device 130 . The engagement control device 140 may control the operation of the first launch device 110 and the second launch device 120 so that the projectile selected by the aerial threat determination device 130 is launched. For example, when the air threat determination device 130 determines that the type of the air threat is the first air threat, the engagement control device 140 instructs the first launch device 110 to fire the first intercepting projectile, and When the threat determination device 130 determines that the type of the aerial threat is the second aerial threat, the engagement control device 140 may instruct the second launch device 120 to fire the second intercepting projectile. Therefore, it is possible to respond by selecting a projectile according to the type of air threat.

The air threat determination device 130 may detect a target, determine the type of the detected target as a first air threat or a second air threat, and select a projectile to be fired as a target according to the type of the target. As shown in FIG. 2 , the aerial threat determination unit 130 includes a target detection unit 131 , a data calculation unit 132 , and a threat type determination unit 133 .

The target detection unit 131 may be a device for detecting an aerial target. For example, the target detection unit 131 may be a radar. Accordingly, the target detection unit 131 may acquire information such as the position, speed, altitude, movement direction, and flight distance of the target.

In addition, a plurality of target detection units 131 may be provided. The target detection units 131 may be disposed together with each of the first launch device 110 and the second launch device 120 , or may be disposed at a location separate from the launch devices.

The data calculator 132 may be connected to send and receive signals to and from the target detector 131 . The data calculation unit 132 may calculate attribute information including the specific energy of the target detected by the target detection unit 131 . The data calculator 132 includes a specific energy calculator 132a.

In this case, the attribute information is an index for determining the type of the target. That is, since the target has different attribution information depending on the type, the target type can be distinguished by calculating the attribution information of the target.

The specific energy calculator 132a may calculate a specific energy of the detected target. The specific energy calculator 132a may calculate the specific energy of the target using Equation 1 below.

[Equation 1]

specific energy =

의 식에 대입하여, 수학식 1에 사용할 속도를 산출할 수 있다.where G is the gravitational acceleration, H is the target's highest altitude, and V is the target's velocity. The highest altitude of the target may be obtained from the target detection unit 131 . The speed of the air threat may be calculated by adding the speed in the x direction, the speed in the y direction, and the speed in the z direction obtained by the target detection unit 131 . That is, the speed in each direction

By substituting into the expression of Equation 1, the speed to be used in Equation 1 can be calculated.

At this time, when the ballistic missile enters the atmosphere and secures a trajectory to reach the target, it freefalls and rapidly changes speed according to the change in main force in the ascending section, and long-range projectiles are fired without rapid speed change. Also, since a ballistic missile has a higher altitude and a faster speed than a long-range projectile, if the specific energy is calculated using Equation 1, the ballistic missile can have a higher specific energy than a long-range projectile.

Meanwhile, the value of the radar reflection area may be further included in the attribute information. Accordingly, as shown in FIG. 2 , the data calculation unit 132 may further include a radar reflection area calculator 132b for calculating the radar reflection area of the detected target. The radar reflection area calculator 132b may calculate the intensity of the reflected wave amount returned by the electromagnetic wave transmitted by the target detection unit 131 being reflected by the target, and may be expressed as a radar reflection area value.

In this case, ballistic missiles are generally larger in size than long-range shells, but the radar reflection area is different depending on the distance and attitude. Therefore, if the radar reflection area is calculated, the ballistic missile may have a larger radar reflection area value than or a similar value than the orthodox projectile.

The threat type determination unit 133 may determine the detected target type as the first air threat or the second air threat according to the attribute information calculated by the data calculation unit 132 by the threat type determination unit 133 . The threat type determining unit 133 includes a non-energy comparator 133a and a threat type determining unit 133b.

The specific energy comparator 133a may be connected to the specific energy calculator 132a to send and receive a signal. The specific energy comparator 133a may compare the specific energy value calculated by the specific energy calculator 132a with a preset energy value. The set energy value can be set by the user.

The threat type determiner 133b may be connected to transmit and receive a signal to and from the non-energy comparator 133a. If the specific energy value calculated as a result of comparison of the specific energy comparator 133a is equal to or greater than the set energy value, the threat type determiner 133b may determine that the target is the first air threat. When the specific energy value calculated as a result of comparison of the specific energy comparator 133a is less than the set energy value, the threat type determiner 133b may determine that the target is a second air threat.

On the other hand, when the data calculation unit 132 further includes the radar reflection area calculator 132b as shown in FIG. 2 , the threat type determining unit 133 can send and receive signals to and from the radar reflection area calculator 132b. It may further include a radar reflection area comparator (133c) connected. The radar reflection area comparator 133c may compare the radar reflection area value calculated by the radar reflection area calculator 132b with a preset set area value. The setting area value can be set by the user.

In addition, the threat type determiner 133b may be connected to the radar reflection area calculator 132b to send and receive a signal. If the value of the radar reflection area is less than the set area value, the type of the target may be changed according to the calculated value of the radar reflection area. Accordingly, the threat type determiner 133b determines that the target is a second air threat if the radar reflection area value calculated from the target whose specific energy value is less than the set energy value is less than the set area value, and sets the target as a second air threat if the specific energy value is greater than the set area value. can be considered a threat. For example, other threats may include aircraft and the like. Accordingly, the threat type determiner 133b may double check the type of the target to more accurately determine the type of the target.

At this time, a target with a specific energy value greater than or equal to the set energy value is determined as the first air threat regardless of the calculated radar reflection area value. You may not judge the type.

Meanwhile, as shown in FIG. 2 , the air threat determination device 130 may further include a projectile selection unit 134 . The projectile selection unit 134 may be connected to exchange signals with the threat type determination unit 133 . The projectile selection unit 134 is a projectile to be fired as a target among the first intercepting projectile intercepting the first aerial threat and the second intercepting projectile intercepting the second air threat according to the determination result of the threat type determination unit 133 . can be selected. That is, when it is determined that the target is a first air threat, the projectile selector 134 selects the first intercepting projectile as a counter weapon, and when the target is determined as a second air threat, the projectile selector 134 selects the second intercepting projectile. It can be selected as a counter weapon.

For example, the projectile selection unit 134 may select a projectile to be fired as a target according to the type of target and automatically control the operation of the engagement control device 140 . Therefore, it is possible to intercept the target quickly because it automatically selects and responds to the projectile according to the type of target.

Alternatively, after the projectile selection unit 134 selects a projectile to be fired as a target according to the type of target, the selected projectile may be recommended to the user. Accordingly, the user may confirm the recommendation of the projectile selection unit 134 and control the operation of the engagement control device 140 to determine the projectile to be fired at the target. Accordingly, the user can finally select a projectile to be fired by checking the battlefield.

As such, the air threat determination device 130 can directly determine the type of target detected in the air, or the user can easily determine the type of target detected in the air by checking the determination result of the air threat determination device 130 . . Accordingly, a countermeasure can be selected according to the type of target. Accordingly, it is possible to safely protect the defense target by effectively responding to the target.

Meanwhile, the air threat determination device 130 may further include a first evaluation unit 135 as shown in FIG. 3 . When the first intercepting projectile is to be fired (or when the projectile selection unit 134 selects the first intercepting projectile), the first evaluation unit 135 determines the priority of the launchers provided in the first intercepting projectile 110 . to select a launcher to fire the first interceptor projectile as the first air threat. The first evaluation unit 135 includes a first target value calculator 135a , a first target value comparator 135b , and a first emission selector 135c .

The first target value calculator 135a may calculate a first target value for determining the priority of each launcher provided in the first launch device 110 . The first target value calculator 135a may calculate a first target value of each of the launchers using Equation 2 below.

[Equation 2]

first target value =

는 발사기가 제1 공중위협을 요격할 요격확률이고,

는 제1 공중위협에 대한 발사기의 발사체 발사 가능 여부를 나타내는 값이고,

는 발사기가 방어하는 방어목표의 중요도이고,

는 발사기의 요격 가능 거리를 지수로 나타내는 값이다.here,

is the interception probability that the launcher will intercept the first air threat,

is a value indicating whether the launcher can launch a projectile against the first air threat,

is the importance of the defensive target defended by the launcher,

is a value representing the interceptable distance of the launcher as an exponent.

The intercept probability of the launcher may be calculated by the first launcher 110 according to the position of the first aerial threat. As the interception probability increases, the first target value increases.

Whether the launcher can fire the projectile is a value indicating whether the launcher is capable of firing the first interceptor projectile to the first air threat. For example, if the first intercepting projectile is not mounted on the launcher or in a situation in which the first intercepting projectile cannot be fired due to repair, etc., the projectile launch possibility value is 0, and the first intercepting projectile is mounted on the launcher and the first air If it is a situation where it can be fired as a threat, the value of whether the projectile can be fired can be 1. Accordingly, a launcher having a projectile launch possibility value of 0 may be excluded because the first target value is calculated as 0.

The importance can be set by the user according to the value of the defense target, and the importance value can be increased as the value of the defense target is higher. As the importance increases, the first target value increases. The higher the importance value, the higher the first objective value of the launcher defending the corresponding defense target.

The interceptable range of the launcher is an index indicating the distance between the launcher and the air threat when the first air threat is within the range of the first intercepting projectile of the launcher. As the correctable distance increases, the first target value increases. For example, because the upper launcher can intercept a first air threat more safely at a higher altitude than the lower launcher, the launcher with a larger correctable range will fire the first intercepting projectile so that the launcher with the larger correctable range fires the first intercepting projectile. The first target value may be calculated to be larger.

The first target value comparator 135b may be connected to transmit and receive a signal to and from the first target value calculator 135a. The first target value comparator 135b may compare the first target values calculated by the first target value calculator 135a. That is, the first target value comparator 135b may compare the sizes of the first target values of each of the launchers and arrange the first target values in the order of magnitude.

The first emission selector 135c may be connected to transmit and receive a signal to and from the first target value comparator 135b. The first firing selector 135c may select a launcher having the largest first target value using the comparison result of the first target value comparator 135b. Accordingly, it is possible to instruct the selected launcher to fire the first intercepting projectile, or to recommend the selected launcher to the user. Therefore, it is possible to fire the first interceptor projectile from the launcher that can most effectively respond to the first air threat.

As such, when the first launch device 110 defends a single defense target in multiple layers using an upper launcher and a lower launcher, or defends a plurality of defense targets with each of the first launchers 110 , the launchers are evaluated. Thus, it is possible to easily select a launcher to fire the first interceptor projectile to the first air threat. Accordingly, it is possible to quickly respond to the first air threat and increase the interception probability of the first air threat.

Meanwhile, the air threat determination device 130 may further include a second evaluation unit 136 as shown in FIG. 3 . When the second intercepting projectile is to be fired from the launchers of the second launching device 120 arranged to defend one defense target (or when the projectile selection unit 134 selects the second intercepting projectile), the second Second, by setting the priority of the launchers provided in the launcher 120, it is possible to select a launcher for firing the second interceptor projectile against the second air threat. The second evaluation unit 136 includes a second target value calculator 136a , a second target value comparator 136b , and a second emission selector 136c .

The second target value calculator 136a may calculate a second target value for prioritizing each of the plurality of launchers. The second target value calculator 136a may calculate the second target value using Equation 3 below.

[Equation 3]

second target value =

는 발사대가 제2 공중위협을 요격할 요격확률이고,

는 제2 공중위협에 대한 발사대의 발사체 발사 가능 여부를 나타내는 값이고,

는 제2 공중위협과 발사대의 요격 가능 거리를 지수로 나타내는 값이다.here,

is the interception probability that the launcher will intercept the second air threat,

is a value indicating whether the launcher can launch a projectile against the second air threat,

is a value representing the interceptable distance of the second air threat and the launch pad as an exponent.

The intercepting probability of the launcher may be calculated by the second launcher 120 according to the location of the second aerial threat. As the interception probability increases, the second target value increases.

Whether the launcher can fire a projectile is a value indicating whether the launcher is capable of launching a second interceptor projectile against a second air threat. For example, if the launch pad is not equipped with a second intercepting projectile or the second intercepting projectile cannot be fired due to repair, etc., the projectile launch possibility value is 0, If it is a situation where it can be fired as a threat, the value of whether the projectile can be fired can be 1. Accordingly, a launch pad having a projectile launch possibility value of 0 may be excluded because the second target value is calculated as 0.

The interceptable range of the launcher is an index indicating the distance between the launcher and the aerial threat when the second air threat is within the range of the second intercepting projectile of the launcher. As the correctable distance increases, the second target value increases.

The second target value comparator 136b may be connected to transmit and receive a signal to and from the second target value calculator 136a. The second target value comparator 136b may compare the second target values calculated by the second target value calculator 136a. That is, the second target value comparator 136b may compare the sizes of the second target values of each of the launchers, and arrange the second target values in the order of magnitude.

The second emission selector 136c may be connected to transmit and receive a signal to and from the second target value comparator 136b. The second launch selector 136c may select a launch pad having the largest second target value using the comparison result of the second target value comparator 136b. Accordingly, the selected launcher may command to fire the second interceptor projectile, or may recommend the selected launcher to the user. Therefore, it is possible to fire the second interceptor projectile from the launch pad that can most effectively respond to the second air threat.

As such, when the second launch device 120 is provided with a plurality of launchers, it is possible to evaluate the launchers and easily select a launcher for launching the second interceptor projectile to the second air threat. Accordingly, it is possible to quickly respond to the second air threat and increase the interception probability of the second air threat.

Meanwhile, the air threat determination device 130 may further include a target alignment unit 137 as shown in FIG. 3 . When there are a plurality of detected targets, the target alignment unit 137 may align the plurality of targets in a corresponding order. Accordingly, the engagement control device 140 controls the operations of the first launch device 110 and the second launch device 120 to intercept the targets in the order in which the target alignment unit 137 is aligned, thereby effectively targeting the targets. can be effectively dealt with. The target alignment unit 137 includes an arrival time predictor 137a and a correspondence order arranger 137b.

The arrival time predictor 137a may be connected to send and receive a signal to and from the target detection unit 131 . The arrival time predictor 137a may predict the arrival time of each of the plurality of targets at the expected landing point using the information acquired by the target detector 131 . That is, using the moving speed of the target and the distance between the target and the expected falling point, the time for each of the targets to reach the expected falling point may be calculated.

The correspondence order sorter 137b may be connected to send and receive a signal with the arrival time predictor 137a. Correspondence order sorter 137b may sort the corresponding order corresponding to the plurality of targets according to the arrival time predicted by the arrival time predictor 137a. That is, it is possible to sort the order of response to air threats in the order of the smallest predicted arrival time. Accordingly, it is possible to intercept a target having a small predicted arrival time in response.

Meanwhile, the target alignment unit 137 may further include a warhead type determiner 137c as shown in FIG. 3 . The warhead type determiner 137c may determine the warhead type. For example, when the number of targets detected by the target detection unit 131 is from one to two, the propellant and the warhead may be separated, and a target having a propellant may be generally more dangerous than a target without a propellant. Accordingly, the warhead type determiner 137c may determine the warhead type of the target according to whether the target is separated from the propellant. The correspondence order aligner 137b may change the correspondence order by applying a weight to the correspondence order according to the warhead type determined by the warhead type determiner 137c. Accordingly, even if the predicted arrival time of one target is smaller than the arrival time of the other target, when separation of the propellant is detected from the other target, the response order may be changed so that the other target responds before any one target.

When a plurality of targets are detected in this way, a response order may be determined. Therefore, it is possible to respond while effectively intercepting a plurality of targets in order.

As such, although specific embodiments have been described in the detailed description of the present invention, various modifications are possible without departing from the scope of the present invention, and various combinations between the embodiments are possible.
