Description

 System for estimating and attacking threat based on regional protection}

 The present invention relates to a zone threat assessment and attack system for defending friendly forces within a zone as well as self-defense against threat forces approaching on a specific zone basis.

The threat assessment and armed allocation algorithm centered on self-defense carries out the threat assessment and armed allocation for threat forces approaching self-employed.

In this case, the threat assessment centered on the self-ship is useful for increasing the survival rate of the self-ship, but the survival rate of the forces is weak due to the low priority of the threat assessment for threats which are not able to defend and approach threats during the operation.

The technical problem to be solved by the present invention is to provide an area threat assessment and attack method based on the area defense that can not only protect the threat forces to approach a specific area but also allies within the area.

Area threat assessment and attack system based on the area defense for solving the technical problem is a threat element identification unit for identifying whether the threat by detecting at least one threat possible element based on the registered friendly information; A threat degree determining unit that determines a degree of threat as the degree of threat of the threat element; A first threat approach determination unit that determines whether one threat factor according to the threat degree is approaching within a first predetermined radius centered on a ship box; And an attack determining unit configured to determine an attack on the identified threat element when the threat element approaches within the predetermined first radius.

The area threat assessment and attack system may include: a second threat approach determination unit determining whether a threat factor according to the threat degree is approaching within a second radius centered on a friendly force; A defensible determination unit that determines whether a defensive distance of the center of the ship box is reached when the threat element approaches the preset second radius; And if it is not the defensive distance it is preferable to further include an evasion determination unit for recommending the evacuation path to the self-ship and friendly forces and determine the movement.

The zone threat assessment and attack system further includes a threat approach notification unit that notifies the friendly forces that the threat is approaching when the threat approaches within the predetermined second radius.

In the area threat assessment and attack system, it is preferable that the attack decision unit determines the attack of the threat element when the defensive distance is available.

It is desirable that the allies have no defensive capabilities or are below a certain level.

The threat degree determining unit may determine the threat degree by using threat attribute information for each threat attribute predetermined in advance.

The threat attribute includes a type of threat, threat identification information in the identifying step, whether the threat is within a defensive area of the ship, and activation information of the threat.

It is preferable that the self-ship and the friendly forces share the avoidance path and move through the mutual avoidance path to avoid the threat.

 The area threat assessment and attack method based on the area defense according to the embodiments of the present invention sets the priority of the threat against threat forces based on a specific area centered on the self-defense box, thereby protecting not only the self-defense but also allies without defense ability.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The area threat assessment and attack system based on the area defense according to the embodiment of the present invention is useful for increasing the survival rate of the self-ship, but it is useful for increasing the survival rate of the self-ship, but it does not have the ability to protect the friendly forces and threats approaching the threat during operation. In order to solve the weakness of the survival rate of the forces due to the low priority of the threat assessment, the threat assessment not only for evaluating the threat of self-defense but also for the threat approached by the threat forces is carried out and the armed allotment and allied forces for the defense of friendly forces are performed. We propose a system for performing algorithms that make recommendations for the movement of forces and recommendations for the movement of ships.

Referring to FIG. 1, a system for performing a threat assessment and attack method will be described. The threat assessment and attack system 10 according to the present embodiment includes a threat identification unit 100 and a threat degree determination unit 200. , The first threat transfer determining unit 300, the attack determining unit 400, the second threat approach determining unit 500, the threat access notification unit 600, the defensible determining unit 700, and the evasion determining unit 800. It is configured to include.

Hereinafter, a process of performing the process of the system 10 for performing a threat evaluation and attack method will be described with reference to FIG. 2. 2 is a flowchart illustrating a process performed in a zone threat assessment and attack system based on zone defense according to an embodiment of the present invention. The element is detected to identify whether it is a threat (S100).

The threat degree determining unit 200 determines a threat degree as a threat degree of the threat factor (S200), and the first threat approach determining unit 300 is within a first radius that is set based on one threat factor according to the threat degree. It is determined whether the approach (S300).

The attack determining unit 400 determines an attack on the identified threat element when the threat element approaches the predetermined first radius (S400).

In addition, the second threat approach determination unit 500 is a threat determination unit centering on friendly forces, and determines whether one threat factor according to the threat degree is approaching within a second predetermined radius centering on friendly forces (S500).

The threat element access notification unit 600 notifies the friendly forces that the threat element has been approached when the threat element approaches the predetermined second radius (S600). After notification of the access fact, the defensive determination unit 700 determines whether the threat factor is the defensive distance of the center of the self defense box when approaching the threat within the predetermined second radius (S700), and the evasion determining unit 800 defends. If the distance is not possible, the evacuation route is recommended to the ship and allies to determine the movement (S800). In the case of a defensive distance, the attack determining unit 400 determines an attack of a threat factor against friendly forces (S400).

Hereinafter, referring to FIG. 3, the threat identification step S100, the threat degree determination step S200, the first radius approach determination step S300, the threat attack determination step S400, and the area defense base including the same Area threat assessment and attack methods are described in more detail.

FIG. 3 is a detailed flowchart illustrating a method for evaluating and attacking a threat based on area defense according to FIG. 2. The allied force registration step (S50) is a step of registering a plurality of nautical ships to perform the operation together with the self-ship. In this embodiment, the friendly forces are friendly forces are not capable of defense or less than a certain level. A certain level of defensive ability means that even if a defensive ability exists, it is unable to attack or defend itself against factors considered to be a threat in conducting operations with self-defense.

Therefore, the threat evaluation and attack method according to the present embodiment provides a zone defense evaluation and attack method based on a zone defense that can defend not only self-defense against threat forces approaching a specific zone but also previously registered allies within the zone. For the purpose of

Threat detection step (S60) uses the radar to find the enemy, such as detection radar (rader) to launch the radio wave to the target while the radar rotates and receives the reflected wave reflected back to find the target distance and direction, etc. It means to bet.

Threat identification step (S100) is a step of identifying whether the threat capable elements detected by the radar can threaten the actual self-ship or friendly forces and classifies according to the identified threat possibility. In the present embodiment, the identification of threats is classified into four stages: hostile, suspected hostile, nostate, and unknown, depending on the possibility of the threat.

Threats that are judged by the enemy are very likely to pose a threat, and the threats described below will have a high weight applied to them, and they are suspiciously indeterminate, but mean that the threat is rather high. With current information, it is impossible to determine whether to pose a threat, and gourmet means that the element itself is not identified.

The threat identified in the threat identification step (S100) is a target to be attacked or avoided in the threat evaluation and attack method according to the present embodiment, and in the following method, a threat level for the target is determined as the identified threat. Explain. In the threat degree determination step (S200), the threat degree is represented by Equation 1.

In this case, the target category weight (CAT) is preferably a random weight whose target is determined according to air, surface, or submarine as a threat factor.

Target identification weight (ID) is a weight of the hostile, the suspected hostile, the no-statement, and the unknown as the identification of the threat possibility in the threat identification step described above. The self defense area (SDA) is a weight that is given when the maneuver of an enemy target can enter the self defense area.

In addition, the Penetration Factor (PF) is related to the maneuvering information of the threat and is expressed as in Equation 2.

In this embodiment, the target starting weight is PF = 5 * V / (D * (1-(θ / 50) ² ) Where the center of defense (COD) is the center of defense (the position of the ship) and any threat weight (5) is the weight of the target's maneuver (arbitrary constant). V (Velocity) = speed of the target (m / s).

이며, Θ(Theta) 는 표적 침로(Course)가 COD와 표적간 연결선이 이루는 사이각으로

이다.Also, D (Distance) is a straight line distance from the target to the COD depending on the position of the ship (X1, Y1) and the position of the target (X2, Y2).

Θ (Theta) is the angle between the target course and the connection line between the COD and the target.

to be.

More specifically, in the present embodiment, the threat level determining step S200 includes a threat level determining step S200a centered on a self-defense and a threat level determining step S200b centered on a friendly force. In the self-centered threat level determination step (S200a), a target having a high threat value (Score) is determined to have a high priority by the above-described threat score calculation method, and in this embodiment, the threat level determination step (S200a) Calculates the threat level for all threats based on self-hammer center (self-defense center).

The first radius approach determination step (S300) determines whether one threat factor according to the threat degree is approaching within a first radius preset based on the ship's ship. In this case, the threat factor is preferably the threat factor determined as the highest priority, the threat factor having the highest threat level, in the above-described threat level determining step (S200a). Referring to FIG. 3, in the case of self-defense centered defense, when threat assessment of self-hammer-centered threat 1 and threat 2 is performed, threat 1 is ranked first, and therefore, threat 1 is rated as the highest priority. It is then determined whether threat 1 approaches within its first radius.

In this embodiment, the first radius may further include the attackable range of the self-ship to the approach of the threat as the defensive area.

Accordingly, the threat attack determining step S400 determines the attack of the identified threat when the threat approaches the predetermined first radius. In other words, armed assignment and post-engagement engagement assessment for threatening forces centered on self-ship is carried out.

However, referring to FIG. 3, in the case of self-defense centered defense, threat 1 is evaluated as the highest priority threat, so threat 2 is approached to friendly forces after a random time, and in this case, threat evaluation centered on self-defense. Is useful for increasing the survival rate of the ship, but has a low priority for the threat assessment of threats approaching with unprotected allies and threats in operation, and is therefore attacked by threat 2.

Therefore, in the present embodiment, the threat evaluation and attack method establishes a defense system centered on self-defense and friendly forces, and the threat degree determination method (S200) performs a threat-based threat determination (S200b) together with a self-defense center threat determination. .

In the allied forces-centered threat determination step (S200b), a target having a high threat value (Score) is determined to have a high priority by the above-described threat score calculation method, and in this embodiment, the threat determination step includes all threats. The threat rating is calculated based on the position of each of the allies ((X11, Y11), (X12, Y12),…, (X1n, Y1n)), so that the target with the highest score is highest. Determine the threat of the ranking.

Subsequently, the second radius approach determination step (S500) determines whether or not the threat factor is the defensive distance of the center of the magnetic box when the threat element approaches the predetermined second radius. In this case, the second radius is preferably a range in which allies may be attacked in consideration of the attack range of the highest priority threat. If the threat approaches the second radius, allies may be attacked, thus notifying allies, and determining or evading the attack from their own ships.

Therefore, in the present embodiment, the threat approach notification step (S600) is a step of notifying the friendly forces of the fact that the threat is approaching when the threat approaches within the preset second radius, specifically, the threat threat. For allies that are not capable of evaluating the system, the threat identified by the ship will be informed to recognize the expected closest point of contact (CPA) and time of arrival (TTG) along the route of the allies and threats.

Closet Point Approach (CPA) calculates the location closest to an arbitrary time using the course and speed of friendly forces and threats, and the Time To Go (TTG) target It means the time to reach the CPA. Mathematically, the following equation (3) is used.

Equation 3 can be simply expressed as TTG = COS (Θ) * D / S, and the estimated closest contact point (CPA) for the current friendly position (X12, Y12) and the current velocity (Vx, Vy) ( PX, PY) can be represented by Equation 4.

After notifying the friendly forces of the approach of the threat factor, the defensive distance determination step (S700) determines whether the defensive distance of the center of the box when the threat element approaches the predetermined second radius.

Therefore, if the determination result is a defensive distance, the threat attack determination step (S400) determines the attack of the threat factor against the identified friendly forces. In other words, armed assignment and post-engagement engagement evaluation of allies threatened by friendly forces approaching self-ship.

Movement decision step (S800), if it is not a defensive distance recommends the evacuation path to the self and friendly forces and determine the movement. When the movement is determined, the self-defense and the friendly forces share the avoidance path with each other and move through the mutual avoidance path to avoid the threat. Referring to FIG. 4, if a high-risk allied force from an enemy target is outside the defending zone of the ship, there is no defense means, so the friendly ship's evasion maneuver path (Course) can be moved so that the ship can move into the defending zone. Recommend to recommend. If allies are unable to move, it is recommended that their ships move to enter the defensive zone.

Hereinafter, a description will be given of a situation in which the area defense evaluation method based on area defense according to an embodiment of the present invention is applied with reference to FIGS. 6 and 7.

Referring to FIG. 6, a specific defense strategy at the time of defending self defense and at power defense is illustrated. In self-defense, when threats 1, 2, and 3 approach the area under operation, minesweeper is identified as the most dangerous threat against threats 1 and 2, and intercepts threats 1 and 2. While defending threats 1 and 2, threat 3 can shoot down a squad (friendship), so that the ship is safe but the squad can be damaged.

However, in the case of performing the power-based defense strategy proposed in the present invention, not only the self-harm but also the harmless forces can be defended from threats.

Specifically, when threats 1,2,3 approach the area under operation, minesweeper will identify threat 3 as the most dangerous threat by identifying 3 of threats 1, 2, and 3 as the most dangerous threats. After threat 3 is intercepted, threats 1 and 2 are first evaluated as threats, so that not only the ship but also allies can be protected from the threat.

Referring to FIG. 7, a strategy for sharing threat avoidance information is shown. When submarine threat 1 is approaching an area in operation, the minesweeper identifies the approaching threat and evaluates it as a threat. Prepare a plan. When a deception plan is set up to launch a deception machine, the deception machine moves along the deception path, and the mine laying along the avoidance path. If the deception plan is not shared, the submarine will continue its mission without knowing the threat situation, and the antisubmarine threat will reroute the deception to track the deception and track the deception path. Can intercept.

However, as in the present embodiment, when allies share the deception plan, the voyage sees the shared deception plan and evades into a safe area irrelevant to the deception route. Thus, even if the anti-submarine threats reroute along the deception, tracking the deception, the anti-submarine threat will either collide with the deceiver or move to another location without friendly forces.

Meanwhile, the area threat assessment and attack method based on the area defense of the present invention can be implemented in computer readable codes on a computer readable recording medium. Computer-readable recording media include all types of recording systems in which data that can be read by a computer system is stored.

Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage system, and the like, and computer-readable recording media are distributed in networked computer systems. Computer-readable code can be stored and executed in a distributed fashion. And functional programs, codes and code segments for implementing the present invention can be easily inferred by programmers in the art to which the present invention belongs.

It will be apparent to those skilled in the art that various modifications, substitutions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. will be.

Accordingly, the embodiments disclosed in the present invention and the accompanying drawings are not intended to limit the technical spirit of the present invention but to describe the present invention, and the scope of the technical idea of the present invention is not limited by the embodiments and the accompanying drawings. .
