Description

Combat management system and management method thereof}

The present invention relates to a combat management device and a method of operating the same, and more specifically, to a combat management device and a method of operating the same that can accurately classify and manage types of targets.

The combat management device is one of the automated weapon systems that integrates the sensors and weapons mounted on the ship to efficiently perform the functions required for combat. The combat management device collects and integrates target information from anti-aircraft radar, sensors, weapons, networks, operators, etc., and provides it so that operators can easily recognize it.

Meanwhile, anti-aircraft radar is installed on the ground or on ships to detect targets in the air. Targets detected by anti-aircraft radar are identified as friendly targets through a friend identifier, and the identification results are displayed on the display of the combat management device. At this time, because the friend identifier can only identify allies, targets other than those identified as allies are displayed on the display as unidentified targets.

However, since civilian aircraft may be included among targets marked as unidentified targets, a situation arises in which it is impossible to determine whether the unidentified target is an enemy aircraft or a civilian aircraft. Accordingly, commanders have difficulty making command decisions such as shooting at unidentified targets.

Referring to Figures 1 and 2, in an embodiment of the present invention, the combat management device includes a detection unit (110:111) for transmitting and receiving detection signals (S1, S2, S3, S4) to detect targets (T1, T2). , 112), a collection unit (120:121, 122) for collecting flight information (B1, B2, B3) that can be randomly broadcast from targets (T1, T2), and detection signals (S1, S2, S3) , S4) and a processing unit 130 for classifying the targets (T1, T2) using the flight information (B1, B2, B3). Additionally, the battle management device according to an embodiment of the present invention may include a display unit 140 for visualizing target images of the targets T1 and T2 and target information of the targets T1 and T2.

Here, the target (T1, T2) may be one or more, and may include objects flying in the sky, such as manned aircraft such as fighter jets and civil aircraft, and unmanned aircraft such as drones. However, the targets (T1, T2) are not limited to this and may include various objects flying in the sky. At least one of these targets (T1, T2) can be detected from the satellite 30 using its own on-board Global Navigation Satellite System (GNSS) and Global Positioning System (GPS). Location information (P1, P2) can be acquired and retained.

The detection unit 110 may be installed to detect targets T1 and T2 in the sky. At this time, the detection unit 110 may be provided as an anti-aircraft radar capable of transmitting and receiving radar signals to targets T1 and T2 in the sky. At this time, the anti-aircraft radar may rotate the antenna 360° and transmit a radar signal in the same direction at predetermined time intervals, for example, at first time intervals. In addition, the anti-aircraft radar can transmit a radar signal to the air, and can receive a radar signal, for example, an encrypted radar signal, transmitted from the target (T1, T2) that has received the radar signal to be transmitted. Here, the encrypted radar signal refers to a radar signal with a predetermined format and can be used to classify friendly forces. For example, if the radar signal transmitted from the target (T1, T2) has a predetermined format, the target can be classified as friendly, and if the radar signal transmitted from the target (T1, T2) does not have a predetermined format, the target can be classified as friendly. can be classified as other targets. Classifying friendly forces using the received radar signal in this way can be performed in the processing unit 130, which will be described later. Additionally, the detection signals (S1, S2, S3, S4) may include information such as the target's flight position, flight speed, and flight direction.

The detection unit 110 may be provided as a rotating radar, but the detection unit 110 may also be provided as a non-rotating radar such as a phased array radar. If the detection unit 110 can transmit and receive detection signals (S1, S2, S3, S4) for detecting targets (T1, T2) in the air, it is not limited to sonar (SONAR), electromagnetic wave collector (ESM: Electronic Support Measure), IRST (Infra-Red Search and Track), etc.

The collection unit 120 may collect flight information (B1, B2, B3) that can be randomly broadcast from targets (T1, T2) in or above the sky. At this time, the collection unit 120 may continuously collect flight information (B1, B2, B3) randomly broadcast from the targets (T1, T2) at predetermined time intervals. Here, the flight information (B1, B2, B3) may include standardized digital information broadcast using a data link from an Automatic Dependent Surveillance-Broadcast (ADS-b) device mounted on the aircraft. For example, a civil aircraft may be equipped with an ADS-b device that can broadcast flight information (B1, B2, B3) such as the aircraft's identification number, flight speed, flight location, and flight direction. The aircraft is equipped with a Global Navigation Satellite System (GNSS) and a Global Positioning System (GPS), and this location information acquisition device acquires the location information (P2) of the aircraft from the satellite 30. can do. And the aircraft's location information (P2) acquired through the location information acquisition device can be randomly broadcasted using a data link at predetermined time intervals through the ADS-B device. At this time, the ADS-b device converts the aircraft's location information (P2) as well as flight information (B1, B2, B3), which integrates other information such as the aircraft's identification number, flight speed, and flight direction, into standardized digital information. It is converted and broadcast randomly on the ground and in the air at predetermined time intervals using a data link. At this time, the ADS-b device can broadcast flight information, such as digital information, about every 1 second. Flight information broadcast from the ADS-b device can be received through a receiver mounted on an aircraft flying around the aircraft or a receiver installed at a control center on the ground. Compared to radar, ADS-b devices can broadcast aircraft flight information with little effect from terrain features.

The collection unit 120 collects flight information (B1, B2) automatically broadcast from civil aircraft flying at various altitudes, for example, civil aircraft flying at low altitudes of about 4000 feet or less and civil aircraft flying at high altitudes exceeding 4000 feet. , B3) can be received and collected. Additionally, the collection unit 120 may collect each flight information (B1, B2, B3) broadcast from one or more targets (T2) in the sky.

The detection unit 110 and the collection unit 120 may be installed in the same place or may be installed in different places. For example, the detection unit 110 and the collection unit 120 may be installed on the ship 20 or at a control center on the ground. Alternatively, the detection unit 110 may be installed in a control center on the ground, and the collection unit 120 may be installed in the ship 20. Hereinafter, the detection unit 110 and the collection unit 120 are illustrated as being installed in the vessel 20.

The processing unit 130 uses the detection signals (S1, S2, S3, S4) received from the detection unit 110 and the flight information (B1, B2, B3) collected from the collection unit 120 to target (T1, T2) can be classified. The processing unit 130 extracts the first location information of the target (T1, T2) using the detection signals (S1, S2, S3, S4), and uses the flight information (B1, B2, B3) to extract the first location information of the target (T1, Using the extractor 131 to extract the second location information of T2), the detection signals (S1, S2, S3, S4), and the flight information (B1, B2, B3), the target (T1, T2) is identified by friendly forces, the United States, It may include a classifier 132 for classification as either an identification target or a civil aircraft.

The extractor 131 extracts the first position information of the target (T1, T2) using the detection signals (S1, S2, S3, S4), and uses the flight information (B1, B2, B3) to extract the first position information of the target (T1, The second location information of T2) can be extracted. At this time, the extractor 131 may extract the first location information and the second location information of the targets T1 and T2 based on the locations where the detection unit 110 and the collection unit 120 are installed. For example, when the detection unit 110 and the collection unit 120 are installed in a ship, the extractor 131 can extract first and second location information of the targets T1 and T2 based on the ship. At this time, the first location information and the second location information may include various information that can determine the absolute and relative positions of the target, such as the latitude and longitude where the target is located, the distance from the ship, and the direction. That is, the detection signals (S1, S2, S3, S4) and flight information (B1, B2, B3) include information such as the flight position, flight speed, and flight direction of the target (T1, T2), so the extractor (131 ) can extract first and second location information of the target (T1, T2) using detection signals (S1, S2, S3, S4) and flight information (B1, B2, B3). The first location information and the second location information may include the direction and distance of the targets T1 and T2 based on the ship 20 on which the detection unit 110 and the collection unit 120 are installed.

Meanwhile, a plurality of targets (T1, T2) may exist in the sky, and the detection unit 110 may receive detection signals (S1, S2, S3, S4) from a plurality of targets (T1, T2) and collect them. Unit 120 may collect flight information (B1, B2, B3) from a plurality of targets (T1, T2). In this case, the extractor 131 may extract first and second location information for each of the plurality of targets T1 and T2.

The classifier 132 includes a first classifier 132a for classifying the target (T1, T2) as a friend using detection signals (S1, S2, S3, S4), and a first classifier (132a) for classifying the target (T1, T2) as a friend using detection signals (S1, S2, S3, S4). and a second classifier 132b for classifying the target (T1, T2) as an unidentified target or a civil aircraft using the flight information (B1, B2, B3).

The first classifier 132a may classify the targets T1 and T2 as friendly if the received detection signals S1, S2, S3, and S4 are in a predetermined format. In addition, if the received detection signal (S1, S2, S3, S4) is not in a predetermined format, the first classifier (132a) classifies the target (T1, T2) as a target other than an ally, and the received detection signal ( S1, S2, S3, S4) can be delivered to the extractor 131.

The first classifier 132a may prepare a radar signal to be transmitted through the detection unit 110. Additionally, the first classifier 132a may analyze the radar signal received from the detection unit 110, for example, an encrypted radar signal, and classify the detected target as a friend. That is, the first classifier 132a may include an interrogator (not shown) and a responder (not shown). The interrogator generates a radar signal, for example, a code propagation of a predetermined format and transmits it through the detection unit 110. do. The transponder receives and analyzes the radar signal received from the detection unit 110, for example, an encrypted code radio wave transmitted from the target, identifies whether the target is friendly, and classifies the target as friendly or other target according to the identification result. can do. At this time, other targets refer to targets other than friendly forces and may include civilian aircraft and unidentified targets. If the target that transmitted the detection signal (S1, S2, S3, S4) is identified as a friend, the first classifier 132a classifies the target as a friend, and if it is identified as not a friend, the first classifier 132a classifies the target as another target and receives the signal. The detected detection signals (S1, S2, S3, S4) can be transmitted to the extractor 131. And the extractor 131 may extract first location information of the targets T1 and T2, for example, other targets, using the detection signals S1, S2, S3, and S4 transmitted from the first classifier 132a.

The second classifier 132b uses the detection signals (S1, S2, S3, S4) and flight information (B1, B2, B3), and the first and second location information extracted from the extractor 131 to determine the target. can be classified as an unidentified target or a civil aircraft. At this time, the second classifier 132b classifies the target (T1, T2) as a civil aircraft if the first location information and the second location information match, and if the first location information and the second location information do not match, the second classifier (132b) classifies the target (T1, T2) as a civil aircraft. T2) can be classified as an unidentified target. Here, matching the first location information and the second location information means that the first location information and the second location information match, or that the first location information and the second location information are included in a preset error range. For example, the first location information and the second location information may have longitude and latitude coordinate values, and the preset error range is the allowable coordinate value difference between the first location information and the second location information. It may be 5% or less or 2% or less with respect to the coordinate value or the coordinate value of the second location information. Alternatively, the first location information and the second location information may include the direction and distance from the ship 20 to the target, and the preset error range is the allowable direction difference between the first location information and the second location information. and distance difference, and may be 5% or less or 2% or less with respect to the direction and distance of the first location information or the direction and distance of the second location information. At this time, the direction of the first location information and the direction of the second location information are the distance or distance between the target according to the first location information and the second location information using the coordinate value of the first location information and the coordinate value of the second location information. It can be calculated as an angle. However, the preset error range is not limited to this and can be changed in various ways.

According to the above, when a plurality of targets (T1, T2) exist in the sky, the extractor 131 can extract first location information and second location information for each of the plurality of targets (T1, T2). . In this case, the second classifier 132b compares the first location information and the second location information of each of the plurality of targets (T1, T2) with each other, and classifies each of the plurality of targets (T1, T2) as an unidentified target or civilian target. It can be classified as an aircraft. At this time, the second classifier 132b searches for the second location information that has the closest value to each of the first location information among the second location information, and determines on a one-to-one basis whether the searched second location information matches the first location information. You can prepare. And, if the first location information and the second location information match, the second classifier 132b classifies the target as a civil aircraft, and if the first location information and the second location information do not match, the second classifier 132b classifies the target as an unidentified target. You can.

The processing unit 130 may further include a storage unit (not shown) for storing various information generated by the extractor 131 and the classifier 132. In addition, the storage unit can store various information acquired and generated by the detection unit 110 and the collection unit 120.

In this way, the processing unit 130 uses at least one of detection signals (S1, S2, S3, S4), flight information (B1, B2, B3), first location information, and second location information to target (T1, T2). Can be classified as friendly, identified target, or civilian aircraft. Here, unidentified targets are targets other than friendly forces and civilian aircraft, and may include enemy fighter jets, etc.

In this way, when the targets T1 and T2 are classified in the processing unit 130, the classified results may be visualized on the display unit 140.

The display unit 140 may be provided as a screen capable of outputting a target image. The display unit 140 may output map information based on the ship 20 or the ground control station on which the detection unit 110 and the collection unit 120 are installed. At this time, the display unit 140 may display the results classified by the processing unit 130 by overlapping them with the map information. Additionally, the display unit 140 may display the target image and target information by overlapping them. At this time, the target information may include various information such as target type, target identification number, flight speed, flight location, flight direction, first location information, and second location information. The type of target is the result of target classification, meaning friendly forces, unidentified targets, and civilian aircraft. Additionally, the display unit 140 may display the target image in different colors depending on the target type so that the target classification result, that is, the target type, can be easily recognized.

Hereinafter, a method of operating a combat management device according to an embodiment of the present invention will be described.

Figure 3 is a flowchart showing a method of operating a battle management device according to an embodiment of the present invention, and Figure 4 is an example of a method of operating a battle management device according to an embodiment of the present invention, visualizing a target image and target information on the display unit. This is a drawing showing .

The method of operating a combat management device according to an embodiment of the present invention can be used to classify types of targets in the sky and visualize target information about the classified targets using the combat management device described above.

Referring to FIG. 4, the method of operating a combat management device according to an embodiment of the present invention includes a process (S101) of transmitting and receiving detection signals (S1, S2, S3, S4) to detect targets (T1, T2), and The process of collecting flight information (B1, B2, B3) that can be broadcast randomly from (T1, T2) (S102) and detection signals (S1, S2, S3, S4) and flight information (B1, B2, B3) It may include a process (S104, S109, S110) of classifying targets (T1, T2) using .

The detection unit 110 and collection unit 120 of the combat management device may be installed in at least one of the ground control center 10 and the ship 20. For example, the detection unit 110 may be installed in the ground control center 10, and the collection unit 120 may be installed in the ship 20. Alternatively, the detection unit 110 may be installed in the ship 20, and the collection unit 120 may be installed in a ground control station. Alternatively, the detection unit 110 and the collection unit 120 may be installed in the ground control center 10 or the ship 20. Hereinafter, a combat management device including a detection unit 110 and a collection unit 120 is illustrated as being installed on the ship 20.

First, the detection unit 110 installed on the ship 20 can transmit and receive detection signals (S2, S4) to detect targets (T1, T2) in the sky. The detection unit 110 may receive the detection signals S2 and S4 generated by the processing unit 130 and transmit and receive the detection signals S2 and S4 in the same direction at first predetermined time intervals. For example, the detection unit 110 is a rotating radar that rotates at first time intervals and transmits a radar signal (S2) into the sky, and receives radar signals (S2, S4) of a predetermined format from at least one target (T1, T2). ) can be received.

When detection signals (S2, S4) are transmitted from the detection unit 110, at least one target (T1, T2) in the sky, for example, the first target (T1), receives a detection signal encrypted in conjunction with the detection signal (S2). (S2) can be transmitted to the detection unit 110. The detection unit 110 may receive the detection signal S2 from the first target T1 and transmit it to the processing unit 130. At this time, when there are a plurality of targets in the sky, the detection unit 110 may receive detection signals (S2, S4) from at least some of the plurality of targets (T1, T2). Here, multiple targets may include friendly forces and civilian aircraft, and may include various unidentified flying vehicles. At this time, various unidentified aircraft may include enemy aircraft. The enemy aircraft may not respond to the detection signals (S2, S4), but the detection signals do not match the predetermined format in order to confuse friendly forces. (S2, S4) can be transmitted. Accordingly, the processing unit 130 analyzes the detection signals (S2, S4) received from the detection unit 110 to determine whether the targets (T1, T2) are friendly forces, and determines whether the targets (T1, T2) are friendly forces or other targets. Can be classified. The detection unit 110 may receive detection signals (S2, S4) from n targets transmitting detection signals (S1, S2, S3, and S4) among the plurality of targets (T1, T2). In this case, there may be n detection signals (S2, S4) received by the detection unit 110.

Additionally, the collection unit 120 installed on the ship 20 may receive flight information (B2) from at least one target (T1, T2) in the sky, for example, a second target (T2) (S102). At this time, the collection unit 120 may receive the flight information (B2) at a second time interval that is shorter than the first time interval at which the detection unit 110 transmits the detection signals (S2 and S4). For example, the second target (T2) can broadcast its flight information (B2) omnidirectionally every second. The second target (T2) is equipped with an ADS-b device that can broadcast flight information (B2) such as its identification number, flight speed, flight position, and flight direction, and broadcasts its flight information (B2) in all directions. Can be broadcast randomly. The ADS-b device randomly broadcasts flight information, including its own location information obtained from satellite positioning systems and satellite positioning systems mounted on aircraft or ground vehicles, to the ground and the air at predetermined time intervals through a data link. . Such ADS-b devices are mainly mounted on civil aircraft and are not mounted on military aircraft such as fighter jets that do not reveal their location. This is because military aircraft can be attacked if exposed to enemy forces. Accordingly, the flight information B2 collected by the collection unit 120 may be flight information of a civil aircraft.

The collection unit 120 may collect flight information (B2) broadcast from the ADS-b device of the second target (T2) and transmit the collected flight information (B2) to the processing unit 130. At this time, the process of collecting flight information (B2) from the second target (T2) may be performed simultaneously with the process of the detection unit 110 transmitting and receiving detection signals (S1, S2, S3, and S4), or may be performed sequentially. It could be. Alternatively, the process of collecting the flight information (B2) from the second target (T2) may be performed more times than the process of the detection unit 110 transmitting and receiving the detection signals (S2 and S4). This is because the second time interval in which the ADS-b device broadcasts flight information (B2) is shorter than the first time interval in which the detection unit 110 transmits and receives radar signals. Additionally, when there are a plurality of civil aircraft in the sky, the collection unit 120 can collect flight information (B2) broadcast from each of the plurality of civil aircraft.

The collection unit 120 may collect flight information broadcast from at least some of the plurality of targets in the sky, for example, m targets. Accordingly, the number of flight information collected by the collection unit 120 may be m. In this case, the collection unit 120 can continuously collect flight information broadcast from the target at first time intervals, for example, every second. It is assumed that there is only one flight information continuously collected from one target. Additionally, none of the targets in the sky may broadcast flight information, or all targets in the sky may broadcast flight information. Accordingly, the number (m) of flight information can be defined as 0≤m≤n.

First, when the detection signals S2 and S4 are received, the first classifier 132a of the processing unit 130 may compare whether the received detection signals S2 and S4 are in a predetermined format (S103). As a result of comparison, if the received detection signals (S2, S4) are in a predetermined format, the first classifier (132a) can classify the targets (T1, T2) as friendly (S104). On the other hand, if the received detection signals (S2, S4) are not in a predetermined format, the first classifier (132a) may classify the targets (T1, T2) as other targets (S105). At this time, other targets may include civil aircraft in addition to unidentified targets, so other targets can be analyzed and classified as unidentified targets or civil aircraft.

Meanwhile, if the number of targets classified as allies among n targets is x, there may be n-x targets classified as other targets. The processing unit 130 may analyze n-x detection signals and classify other targets as unidentified targets or civil aircraft.

The extractor 131 of the processing unit 130 may receive n-x detection signals through the first classifier 132a and extract first location information for n-x targets (S106). Accordingly, the extractor 131 can extract n-x pieces of first location information.

Additionally, the extractor 131 may extract the second location information of the target using the flight information collected by the collection unit 120 (S107). At this time, when there are m pieces of flight information collected by the collection unit 120, the extractor 131 can extract m pieces of second location information. The first location information and second location information extracted in this way may include the direction and distance of the target from the ship 20. Alternatively, the extracted first location information and second location information may be coordinate values including information on the absolute location of the target, for example, latitude and longitude. However, the first location information and the second location information are not limited to this and may vary.

The extractor 131 may extract first target information of the target using a detection signal and extract second target information of the target using flight information. At this time, if the target that transmitted the detection signal and the target that broadcasted the flight information are the same target, the first target information and the second target information may be the same. On the other hand, if the target that transmitted the detection signal and the target that broadcast the flight information are different targets, the first target information and the second target information may be different from each other.

When the first location information and the second location information are extracted, the second classifier 132b compares the first location information and the second location information (S108) and classifies the target as a civil aircraft or an unidentified target according to the comparison result. can do. If the first location information and the second location information match, the second classifier 132b may classify the target, such as another target, as a civil aircraft (S109). On the other hand, if the first location information and the second location information do not match, the second classifier 132b may classify the target, such as another target, as an unidentified target (S110). Here, matching the first location information and the second location information means that the first location information and the second location information match or are within a preset error range. That is, even if the first location information and the second location information do not match, the difference between the first location information and the second location information is within an acceptable range or is very small.

In addition, as described above, when there are n-x pieces of first location information and m pieces of second location information, the second classifier 132b selects the second location information with the closest value to the first location information among the m pieces of second location information. You can search and compare the searched second location information and first location information one-to-one. For example, the second classifier 132b may search for the second location information having the closest value to each of the n-x pieces of first location information from each of the m pieces of second location information and perform one-to-one matching. Then, the one-to-one matched first and second location information are compared with each other, and if the first and second location information match, the target with the first location information can be classified as a civil aircraft (S109). . On the other hand, if the first location information and the second location information do not match, the target with the corresponding first location information can be classified as an unidentified target (S110). At this time, if the number of civil aircraft is y and the number of unidentified targets is z, the sum of the number of civil aircraft and the number of unidentified targets is equal to n-x, the number of first location information (y+z=n-x) can do. Additionally, the number y of civil aircraft may be equal to the number m of second location information (y=m).

Additionally, if m pieces of second location information are matched with n-x pieces of first location information, and both the matched first location information and second location information are identical, all other targets can be classified as civil aircraft.

Here, a case in which second location information is extracted from the extractor 131 has been described. However, if there are no civilian aircraft among the targets in the air, flight information is not collected, and there may be no second location information extracted. In this case, targets classified as other targets in the first classifier 132a may be classified as unidentified targets (S110). At this time, since there is no second location information to be extracted, a result in which the first location information and the second location information do not match may be derived in the process of comparing the first location information and the second location information. Accordingly, targets, i.e. other targets, can be classified as unidentified targets.

In this way, the processing unit 130 can classify targets as friendly forces, unidentified targets, and civilian aircraft. In this way, when the target is classified, the classified result can be visualized (S111) on the display unit 140. The process of visualizing the classified results may output target images and target information to the display unit 140.

Figure 4 is a diagram showing a state in which the target image and target information about the target are output to the display unit 140. Referring to FIG. 4 , target images having different colors may be displayed on the display unit 140 for each classification of the target, for example, each type. Alternatively, target images having different shapes for each classification or type of target may be output on the display unit 140. When outputting a target image to the display unit 140, map information based on the ship 20 can be output to the display unit 140, and the target image can be overlaid on the map information. Additionally, when at least one of the target images output on the display unit 140 is selected, target information corresponding to the selected target image may be output as text.

Accordingly, the commander can easily recognize target images and target information classified by type on the display unit 140, and can quickly make command decisions about the target accordingly.
