Description

Apparatus and method for recommended interception point based on damage minimization, computer-readable recording medium, and computer program

The embodiment relates to an intercept point recommendation device based on damage minimization in order to minimize damage that may occur due to defense of a high-speed vehicle.

Currently, the Republic of Korea is always exposed to the threat of high-speed aircraft from North Korea, and it is unknown when, where, where, and how much it will fly. In order to properly respond to these threats, the ROK military has deployed and is operating various interceptors.

Interception of existing high-speed aircraft depends on the range of the interceptor missile and important facilities to be protected, and there is no consideration of damage such as falls or fragments or damage to the city center. This is based on the assumption that North Korea will launch high-speed vehicles or missiles mainly at military facilities and other important national facilities, and the facilities and priorities to be protected from enemy high-speed vehicles are determined in advance. In other words, if it is expected to land in an area other than a predefined critical facility, the timing of the interception will be determined by the intercept unit.

However, direct/indirect damage to land, sea, and air caused by interception is not considered, and it is decided based on the commander's experience, knowledge, and operation. In the event of a war reaction, high-speed vehicles are expected to fall not only on military facilities and important facilities, but also on various areas, whereas high-speed vehicles, such as ballistic missiles, fall in addition to predefined protection facilities. This situation is made very subjectively and passively, and judgment may be delayed or cause enormous damage depending on judgment. This means that the damage to the drop point and surroundings of the high-speed vehicle cannot be standardized and quantified, and judgment to minimize damage cannot be guaranteed.

Korean Patent Application Laid-Open No. 10-2012-0050176 (published on May 18, 2012) Korean Patent Publication No. 10-2012-0137332 (published on December 20, 2012) Korean Patent Laid-Open Publication No. 10-2012-0139635 (published on December 27, 2012) Korean Patent Laid-Open Publication No. 10-2012-0139636 (published on December 27, 2012) Korean Patent Laid-Open Publication No. 10-2012-0137333 (published on December 20, 2012) Korean Patent Application Laid-Open No. 10-1988036 (Registered on 6/04/2019)

The problem to be solved by the present invention is to automate the process in which such passive and subjective bias intervention is possible, and to minimize damage by optimizing the interception time through consideration of direct/indirect damage to various factors. In addition, by quantifying and quantifying damage and making it objective, it is possible to provide a timely basis to help the commander's judgment, thereby reducing the burden on the commander.

However, the problems to be solved of the present invention are not limited to those mentioned above, and other problems to be solved that are not mentioned can be clearly understood by those of ordinary skill in the art to which the present invention belongs from the following description. will be.

The intercept point recommendation device of the embodiment includes an actual damage analysis unit that analyzes damage caused by a high-speed aircraft and analyzes each damage factor, a training management unit that identifies the risk level and the commander's policy for the damage, and the risk level and the commander's policy It may include a recommendation writing unit for recommending to the commander at least one or more intercept points at which the risk is minimized based on the above.

The recommendation creation unit may determine the commander's policy by using selection information of the commander selected through simulation as an input to the machine learning model.

The risk may be calculated by Equation (1).

[Equation 1]

(Where Sum is the risk, μ is the correlation coefficient (0<μ≤1), Didm means direct damage, and IndDm means indirect damage)

The direct damage may be calculated in consideration of human life, facilities and equipment factors.

The indirect damage may be calculated in consideration of human life, land, infrastructure, service and period factors.

In order to calculate the damage, it may further include a data management unit for storing at least one or more of map information, the number of population in each region, traffic information, facility information, and housing information.

The method may further include an engagement control unit that receives engagement state information and engagement results for the at least one intercept point through a data link and provides the information to the commander.

In addition, the intercept point recommendation method of the embodiment includes the steps of identifying the damage caused by the high-speed aircraft and analyzing each damage factor, the risk of the damage and the commander's policy, based on the risk level and the commander's policy It may include recommending to the commander at least one or more intercept points at which the risk is minimized.

In addition, the embodiment is a computer program stored in a computer-readable recording medium, wherein, when the computer program is executed by a processor, the steps of analyzing the damage caused by the high-speed aircraft by identifying the damage caused by the high-speed aircraft; Instructions for causing the processor to perform an operation comprising: identifying the risk level and the commander's policy; may include.

According to an embodiment of the present invention, it is possible to help the commander's decision by quantifying and objectifying various damage factors in the defense of a high-speed aircraft, which is mostly made through subjective judgment such as personal knowledge and experience of the commander.

In particular, for example, when a large number of enemy high-speed aircraft are launched and they are heading to military facilities, national important facilities, civilian facilities, dangerous areas or densely populated areas, it is not easy for the commander to determine the order of interception and the burden on the individual commander is very high. It is expected that the present invention can alleviate this burden and provide support for the commander's command decision. In addition, various elements can be utilized for damage calculation through the present invention, and damage can be objectified and automated to enable a commander to perform an efficient and effective operation.

Hereinafter, the embodiment will be described in detail with reference to the drawings.

As shown in FIG. 1 , the damage minimization-based high-speed aircraft defense command decision support device 100 according to an embodiment of the present invention includes a user interface unit 110 , a fragment analysis unit 120 , a damage analysis unit 130 , It may include a data management unit 140 , an engagement control unit 150 , a recommendation writing unit 160 , a training management unit 170 , and an actual damage analysis unit 180 . Here, the damage analysis unit 130 may be used as a separate damage analysis device, and the recommendation creation unit 160 may also be used as a separate interception point recommendation device.

The user interface unit 110 displays detailed information such as a launch position and an expected fall position of the detected high-speed vehicle and a movement path. Here, the high-speed vehicle may be a ballistic missile, and the type is not limited thereto.

As shown in FIG. 2 , immediately after the high-speed vehicle is detected through the radar, the expected drop position and a certain radius according to the type of warhead are displayed in a specific color to indicate an area directly affected by damage. In addition, different colors are displayed in a certain radius from the falling position to indicate the 2nd and 3rd damage area. At this time, the radius is defined in advance according to the bullet type of the high-speed vehicle and managed through the data management unit 140 .

In addition, the bullet type of the high-speed vehicle can be automatically identified by the system or input by the user. If the bullet of a high-speed aircraft is nuclear or biochemical, it can cause various side effects, such as modifying the DNA of the human body, so the damage should be predicted and added to the total damage. In addition, if there are important facilities such as telephone offices or telecommunication facilities within the scope of the drop, indirect damage considering the paralysis of related services due to the collapse of these facilities can be considered.

There may be two methods in which information of the detected high-speed vehicle is transmitted to the user interface unit 110 . There are a method of receiving information of a high-speed vehicle through interworking with an external detection radar system, and a method of directly inputting the information. Interlocking with the external detection radar system is possible for all systems equipped with a radar capable of detecting high-speed aircraft, and the transmission method, period, detailed information or additional information is applied as determined through the interlocking control document. In the direct input method, the user can create a new high-speed aircraft scenario or load a pre-written scenario, and this can be used for personal training. All decisions made by the user during the training process are used as feedback to learn the policy of the user (or commander).

The user logs in through the user interface 110 , selects training, and then creates a new scenario or selects a scenario load. When creating a new scenario, select the total number of high-speed vehicles, the warhead of the high-speed vehicle, and the bullet type of the high-speed vehicle, and enter detailed information such as the launch point, launch angle, and drop point. Newly created scenarios can be saved in a predefined directory or saved in a path selected by the user.

The user interface 110 displays the calculated risk index within the falling range of the high-speed vehicle, and when each risk index is clicked, the measured values of each element in the corresponding area may be displayed through the user interface 110 .

The fragment analysis unit 120 calculates the damage range by applying the fragment dispersion model. In this case, one of several previously developed models can be applied for the fragment dispersion model. The model application criteria should be able to reflect several factors. In other words, select a model that can reflect various factors such as warhead type, launch angle, launch position, speed, intercept point, number of fragments, and ratio to fragment size of the high-speed vehicle.

The damage analysis unit 130 predicts direct or indirect damage based on the damage range calculated by the fragment analysis unit 120 . First, according to the type of high-speed aircraft warhead, direct damage and indirect damage are divided. Indirect damage can be divided into two categories. First, if the warhead of a high-speed vehicle may affect the human body, and second, if the service is unavailable due to destruction of facilities, etc.

First, if the warhead of a high-speed vehicle can affect the human body, if the warhead of a high-speed vehicle is a nuclear or chemical bomb, it is exposed to radiation, damage due to fallout, and infection with various bacteria.

Unavailability of service due to facility destruction is, for example, if the communication facility is destroyed, not only the corresponding area but also the surrounding area or the entire communication network in some areas may be paralyzed. It is necessary to define the factors to be considered in order to formulate the damage and calculate the risk. For example, human life (number of floating population, number of permanent residents), facilities (national infrastructure, commercial facilities, multi-use facilities, residential complexes), equipment (commercial equipment, experiment/test equipment, vehicles), period (short-term, medium-term) , organs) can be considered. Depending on the application, these elements can be added or deleted.

For example, the defense commander of the Navy's high-speed aircraft may consider factors such as marine pollution and its direct and indirect damage, damage to fishing vessels, and damage to nearby islanders. For each element, it can be obtained and defined in advance or aggregated in real time. The pre-acquisition method utilizes accurate statistical data for each element. In other words, the average value of people, facilities, equipment, etc. in all regions of Korea can be applied through institutions that maintain relevant information, such as the National Statistical Office and the National Police Agency.

This predefined method enables manual input by an administrator and automatic input through direct linkage through consultation with related organizations. On the other hand, the real-time aggregation method applies uncertain and approximate data compared to the pre-acquisition and definition method. In other words, it is calculated by applying the method of estimating the average number of people per building and the amount of damage in case of a disaster such as a fire, etc.

The period is an additional factor used to calculate indirect damage. It is divided into short-term, medium-term, and long-term so that damage is calculated and reflected in the risk level. can be applied. That is, nuclear warheads can have a long-term effect in consideration of the half-life or effects on the human body.

If the damage period is less than one year, the reflected value (P) may be 0.25. If the damage period is 1 to 10 years or less, the reflected value (P) may be 0.5. If the damage period is 10 to 50 years or less, the reflected value (P) may be 0.75. If the damage period exceeds 50 years, the reflected value (P) may be 1.0.

The risk calculation formula may be calculated as in Equation 1.

[Equation 1]

), Didm은 직접 피해, IndDm은 간접피해를 나타낸다.In this case, μ is the correlation coefficient (

), Didm represents direct damage, and IndDm represents indirect damage.

The direct damage Didm can be calculated as in Equation (2).

[Equation 2]

을 만족할 수 있다.In this case, a (person),

It is calculated taking into account (facility), γ (equipment), d, e,

can be satisfied

The indirect damage InDm may be calculated as in Equation (3).

[Equation 3]

(토지, 기반), p(기간)을 고려하여 계산된다. d, e는 각각 상관계수이며,

을 만족한다At this time, the indirect damage IndDm is a (life),

It is calculated considering (land, foundation) and p (period). d and e are the correlation coefficients, respectively,

satisfy

For further simplification, we can quantify each element.

First, the damage can be quantified and utilized as follows to calculate the casualties. Here, the unit is a person.

a<100 One 101 ≤ a < 500 2 501≤ a < 1000 3 1001≤ a <5000 4 5001≤ a < 10000 5 10001≤ a <15000 6 15001≤ a <30000 7 30001≤ a <50000 8 50001≤ a < 100000 9 a≥100000 10

It can be quantified like human life for facilities and equipment, and in this case, the unit can be the amount of damage.

The data management unit 140 stores and manages various information for calculating damage, such as map information, the number of populations in each region, traffic information, facility information, and housing information. As mentioned earlier, this information can be established automatically or manually. In the case of automatic construction, data can be established and updated through consultation with related organizations such as the National Statistical Office, Fire Department, and National Police Agency. On the other hand, in the case of manual construction, there is a method for the administrator to manually input information using the information disclosed online without consulting with the relevant organization, but it is relatively inaccurate. In addition, if the data is received as a file after consultation with the relevant organization and entered manually, it is possible to enter it directly or to automatically enter it by analyzing the document.

When related data is automatically input, it is updated periodically, and may be updated according to the set value such as hourly, daily, weekly, monthly, etc. Even if it is linked through consultation with related organizations, the accuracy of the data cannot be guaranteed, and it is used only as a basis for calculating the risk.

The recommendation writing unit 160 recommends to the commander a maximum of three interception points at which damage can be minimized from the initial interception point, and the recommended interception points are the time points at which the risk calculated through the damage analysis unit 130 is minimized. admit.

The recommendation writing unit 160 considers the characteristics (altitude, distance, etc.) of the interceptor unit and missile on the expected trajectory drawn in a straight line from the launch point (or current position) to the expected drop position, and the interception point or point at which it is possible to intercept multiple interception points. is selected as a candidate group. In the case of not intercepting, that is, in the case of a high-speed aircraft directly falling to the expected landing point, the maximum value is smaller than the maximum value and the top three points arranged in the order of the minimum value are recommended to the commander.

The method of selecting the interception candidate group on the expected trajectory identifies the candidates by repeating the dispersion range analyzed through the fragment analyzer 120 at the expected fall position to the first interception possible point in the same range overlapping with this starting point.

As shown in FIG. 2 , the dispersion range is recalculated through the fragment analyzer 120 by using a point as far as the radius of the dispersion range from the expected drop position as the first intercept candidate.

The second intercepting candidate is determined as a point away from the center of the first intercepting candidate by the radius of the dispersion range. In this way, the intercept candidate points up to the current location of the high-speed vehicle are identified, the expected damage and risk of each candidate are calculated in the damage analysis unit 130, and the top three candidates are recommended to the commander by ranking in the order of the minimum value. . Also, the recommendation writing unit 160 may define a recommendation policy.

In other words, the recommendation policy can be defined by considering the two factors of risk and the commander's policy, but when the risk and policy conflict, the priority of the high-risk intercept candidate is given higher priority. This is to prevent excessive risk by excluding excessive policy-based recommendations. For this purpose, recommendations according to the commander's policy can be defined and applied in actual operation, such as applying only when the same level of risk is indicated.

Alternatively, as shown in FIG. 3 , the dispersion range may be recalculated through the fragment analyzer 120 for one damaged area.

The engagement control unit 150 instructs the interceptor to intercept the three recommended candidates or the interceptor at another point in time (or point) determined according to the commander's judgment to the interceptor through the data link, and the engagement status information and The engagement result is received and provided to the commander through the user interface 110 .

The training management unit 170 provides a high-speed aircraft intercept simulation training function to improve the commander's coping ability. The simulation training is conducted based on a scenario, and you can create a new scenario or load an existing scenario and use it. At this time, the data management unit 140 may be stored or an existing scenario may be loaded.

In the scenario, you can select the warhead, bullet type, etc. of the enemy high-speed aircraft unit and the high-speed vehicle, and input the launch location, launch angle, and fall position. In addition, it is possible to select and position the interceptor interceptor unit, the type of interceptor missile, etc. In addition, for training, the commander proceeds while logging into his/her account, and all selections of the commander are recorded and stored through the data management unit 140 .

The recommendation creation unit 160 may determine the commander's policy by using all selection information of the commander as input to the machine learning model. Here, the machine learning model may be provided in the recommendation writing unit 160 or provided outside the recommendation writing unit 160 .

These choices made during the training period are used for each commander's policy analysis, and the commander's personal profile is created and updated based on the analyzed policy. Profile update can be done every time selection occurs, or it can be processed for all data or data for each commander at once after training is all over.

The policy analysis process is made based on the stored commander's selection record, and the frequency is calculated for each factor applied to the damage calculation, applied and managed. The analyzed policy is the basis for composing the profile of each commander. It can be used later when recommending an intercept point based on the profile. That is, it is possible to recommend the top three candidate intercept points that match the commander's policy among several candidate intercept points.

The actual damage analysis unit 180 is to analyze the actual damage caused by the high-speed aircraft by damage factors. This is used to close the gap with the calculated damage and risk for recommendations to the commander. The actual damage input is entered through the user interface 110, and when recommended after input, the cause is found through comparison of the calculated damage and each element, and the cause is notified to the manager, and the manager can arbitrarily adjust the data of the data management unit 140 or 130), adjust the weight values used in the process. This process is repeated until the difference between elements reaches a certain threshold value.

Here, the minimization-based high-speed vehicle defense command decision support method can be performed in the minimization-based high-speed vehicle defense command decision support device, which will be briefly described again.

In more detail, as shown in FIG. 7 , when the high-speed vehicle is detected (S100), warhead information of the high-speed vehicle may be input (S101). Then, the fragment dispersion model is applied (S103), and the dispersion range according to the warhead can be calculated (S104). On the other hand, if warhead information is not input, the dispersion range according to the warhead may be calculated using the warhead identification processor (S102) (S104).

When the warhead of the high-speed vehicle is a nuclear or chemical bomb, indirect damage due to the warhead can be predicted (S105, 107). On the other hand, when the warhead of the high-speed vehicle is not a nuclear or chemical bomb, the intercept timing according to the expected trajectory of the high-speed vehicle may be calculated (S105, S106).

Then, an intercept point may be recommended (S108). Subsequently, an engagement command is made (S109), and actual damage can be calculated (S110). Then, the prediction risk error may be calculated and reflected (S111). Finally, it is possible to update the evaluation and commander's profile (S112).

The damage minimization-based recommendation creation method includes the steps of identifying the damage caused by the high-speed aircraft and analyzing each damage factor, the risk level for the damage and the commander's policy, and the risk level based on the risk level and the commander's policy It may include the step of recommending to the commander at least one or more intercept points at which the minimum is.
