EMBODIMENT OF THE INVENTION Hereinafter, the target management system, apparatus, and method of this invention are demonstrated in detail with reference to drawings.

For reference, the 'point target' described herein refers to a target whose coordinate information is found, and the 'azimuth target' refers to a target whose only azimuth angle is found. Point targets can be obtained, for example, via radar, and azimuth targets can be obtained, for example, via electromagnetic wave direction detection equipment.

'Fusion' refers to processing a single point target determined as the same target among a plurality of point targets obtained from a detection sensor, and 'Comparative Fusion' performs the same processing as 'Fusion' but Refers to a point target obtained by fusing a plurality of point targets obtained from a detection sensor and a point target obtained from a communication network.

When a point target of a physically identical object is acquired through a plurality of detection sensors, a plurality of target information is introduced into the target management system. At this time, it is a matter of which point target the fusion is to be performed. The point target which is the center of the fusion process will be referred to as the 'parent target', and the point target to be fused to the parent target will be referred to as the 'child target'. The parent target may be determined by the priority given according to the accuracy of the detection sensor. If it is difficult to determine the accuracy of each detection sensor, ie its own error, the priority may be given arbitrarily.

'Association' refers to estimating an azimuth target whose azimuth coincides with or approximates azimuth point among azimuth targets as the same as the point target.

'Pairing' refers to establishing a correlation between a plurality of point targets. For example, when a plurality of point targets are detected together within a certain radius for a certain time, the detection object represented by the point target may be expected to make a flight formation. In this case, the display unit (target information display unit) draws a line between the point targets and displays the line. The process of generating such a line is called pairing.

'Coupling' refers to identifying and setting the same between a plurality of azimuth targets. In general, when two signals having different azimuth angles are detected, the two azimuth targets are identified. However, if two radars are used in a single object, for example a trap, two frequencies and two azimuths are detected for that trap. At this time, it is unreasonable to manage with two orientation targets. Therefore, by comparing and analyzing the characteristics of the corresponding vessel (Trap using two radars in the above example) and the detected bearing target, the two bearing targets are identified as one bearing target. It can be set as, which is called a join process. In general, the object of engagement will be a plurality of azimuthal targets having the same or approximate azimuth.

'Azimuth crossover' refers to the generation of point targets of intersections of a plurality of azimuth targets for the same detector. For example, if there are a plurality of payloads (traps or aircraft) equipped with the target management system or apparatus of the present invention, if the bearing targets for the same detection detected in each payload are shared through a communication network, Coordinates of the detected object can be extracted from the intersection of the identified bearing target and the bearing target identified by the other payload. The extracted coordinates become a point target.

1 is a block diagram illustrating a target management system of the present invention.

The target management system shown in FIG. 1 includes a first target acquisition unit 20 for receiving first target information from the detection sensor 10, a third target acquisition unit 60 for receiving third target information from a communication network, and A fourth target which is the comparative fusion-processed target information after the first target information and the second target information of the past are fused and the second target information and the third target information, which are the fusion-processed target information, are compared and fused. The target management unit 100 performs at least one of information association processing, combining processing, pairing processing, and azimuth cross-processing processing.

The detection sensor 10 is a sensor for detecting an object, and the object detected by the sensor will be referred to as a detection object. In addition, the object shall refer to the object which can be detected by a detection sensor. The detection sensor emits radio waves and receives and analyzes the radio waves reflected from the detection object to detect the coordinates of the detection object, and receives and analyzes the energy emitted from the detection object. The sensor may include a sensor for acquiring a point target and a sensor for acquiring an azimuth target, such as an electromagnetic wave direction detecting device for determining an azimuth angle of a target by analyzing a received radio wave.

The first target acquisition unit 20 receives target information (point target or azimuth target) detected by the detection sensor and transmits the target information to the target management unit 100. The first target acquirer 20 may include an interface for receiving target information from the detection sensor and a data converter (including an amplifier) for converting the received target information into data that may be processed by the target manager. The target information acquired by the first target acquisition unit is referred to as first target information.

The third target acquisition unit 60 receives the third target information from the communication network. To this end, the third target acquirer may include a communication means capable of using a corresponding communication network and a signal converter configured to demodulate or convert the received data into a signal usable by the target manager. The communication means may be integrally formed with the communication unit 50 to be described later. Target information acquired by the third target acquisition unit is referred to as third target information.

The target management unit 100 generates the second target information by fusion processing the first target information, and generates fourth target information by comparing and fusion processing the third target information with the second target information. That is, the target management unit performs a fusion process for the point target in the first target information and the second target information and a comparative fusion process for the point target in the second target information and the third target information. Thereafter, at least one of associating, combining, pairing, and azimuth cross-processing is performed on the fourth target information on which the comparison fusion processing is completed.

When receiving the first target information, the target management unit performs a fusion process and then performs a comparison fusion process with the third target information previously input through the communication network. Upon receiving the third target information, the target management unit performs a comparison fusion process with the second target information that has been previously fused. If the first target information and the third target information are input at the same time, the fusion process may be performed first and then the comparison fusion process may be performed.

As to the association, coupling, pairing and azimuth cross-section processing, the processing order can be set by the operator's choice.

Referring to the above configuration, the first target information obtained from the detection sensor and the third target information obtained from the communication network are associated, combined, paired, and azimuthal cross-processed after the fusion process and the comparative fusion process are performed in the target management unit. It is managed consistently and systematically according to the stages. In terms of the point target and the orientation target, the fusion processing and the comparative fusion processing of the point target are first performed, followed by pairing processing for the point target, associating processing for the orientation target, binding processing, and orientation crosslinking processing.

In the past, such a processing sequence was not provided, so that different management methods were applied to each target information, so that uniform and consistent target management was not achieved. This situation can be improved and target management can be improved in a consistent manner. It is easy to write and provide a program to perform.

According to the above structure, although the 5th target information which is the target information which processed various processes from the target management part is provided, 5th target information can be utilized variously.

Specifically, the target management system includes a display unit 30 for displaying fifth target information, which is target information processed by the target management unit, an arming control unit 40 for controlling the arming to aim the coordinates indicated by the fifth target information, and the fifth unit. It may further include at least one of the communication unit 50 for transmitting target information through the communication network.

In this case, when there are a plurality of target management systems including a communication unit, the third target information input through the communication network to each target management system may be fifth target information transmitted from the communication unit of another target management system. According to this, since the third target information is managed by the target management unit in another target management system, it can be seen that considerable reliability can be expected except for communication problems (jamming, noise inflow, etc.).

Hereinafter, the configuration of the target management unit will be described in more detail.

The target management apparatus (target management unit) 100 of the present invention generates the second target information by fusion processing the first target information acquired from the detection sensor 10 and the past second target information, and generates the fusion process. Association, combining, and pairing of the target fusion unit 110 and the fourth target information that generate the fourth target information by comparing the converged second target information with the third target information acquired from the communication network to generate fourth target information. And a target processor 130 for generating fifth target information by performing at least one of azimuth cross measurement processing.

The target fusion unit 110 performs fusion processing of the fusion unit 111 for fusion processing the point target in the first target information and the point target in the second target information and the third target information in the third target information resulting from the fusion processing. The comparison fusion unit 113 may be included. In this case, the fusion unit 111 may be integrally formed with the first target acquisition unit 20, and the comparison fusion unit 113 may be integrally formed with the third target acquisition unit 60. In this case, the fusion may be performed or the fusion may not be performed. In any case, the result of the fusion process being performed becomes the second target information. The comparative fusion process may also be performed or the comparative fusion may not be performed. In this case, the result of the comparative fusion process being performed becomes the fourth target information.

Specifically, the object of the fusion processing performed by the fusion unit 111 may be first target information input from each of the plurality of detection sensors at the present time, or may be first target information currently input and first target information previously input. have. The former case corresponds to the case where the first target information is new, and the latter case corresponds to the case where the update continuously detects the detection object indicated by the first target information. In order to process all of the above cases, the target fusion unit fuses each first target information with past, that is, previous, second target information.

For example, referring to an operation after initialization of the fusion unit, when the first target information is input, the fusion unit performs fusion processing with past second target information. The past second target information is the second target information generated by the past fusion process on the basis of the present time. Past second target information is erased due to initialization since it is a result of past fusion processing. Since there is no past second target information according to the initialization, the new second target information as a result of the fusion is the same as the first target information. If the first target information is input simultaneously from the plurality of detection sensors, the fusion process may be performed according to the priority mentioned in the concept of the parent target described above. The first target information input from the detection sensor of the first priority will be the second target information, and the first target information input from the detection sensor of the second priority is the previous second target information (first priority detection). The first target information of the sensor). If it is determined as another target and the convergence is not performed, the first target information of the second priority detection sensor also becomes new second target information. In this case, the second target information becomes two, such as second target information generated from the first priority detection sensor and second target information generated from the second priority detection sensor. If convergence is made, the second target information becomes one piece of second target information generated from the first priority detection sensor. Then, the first target information of the detection sensor of the third priority is fused with two or one second target information according to the previous fusion result. In the former case, the first target information of the third priority detection sensor may be fused with each of the two second target information and may be fused with any one second target information or generate a new second target according to the fusion result. In the latter case, the first target information of the third priority detection sensor may be fused with the first target information and may be fused with the second target information or generate a new second target according to the fusion result. The first target information of the following priority detection sensor is also processed in this manner.

As a result, when the first target information is new, it can be seen that the first target information is fused with the past second target information, and as a result, the first target information is fused.

When the first target information is the update, it means that there is the second target information, which is a fusion process of the first target information of the update target in advance among the second target information in the past. Therefore, the first target information at this time it is reasonable to fuse with the second target information of the past. However, the fusion process at this time may include a process of releasing the past fusion in some cases by analyzing the information of the updated first target information and the past second target information. Specifically, the fusion condition between the updated first target information and the second target information fused with the first target information in the past is examined, and if the fusion condition is not satisfied, the fusion is released and the updated first target information is not found. Generate new second target information for. When the fusion is not released, that is, when the fusion condition is satisfied, the second target information fused in the past is updated based on the updated first target information.

The object to be subjected to the comparison fusion processing in the comparison fusion unit 113 is the second target information and the third target information. In some cases, there may be no one kind of target information, and the result of the comparative fusion process is the same as other types of target information present.

In the comparative fusion process, the second target information may be compared and fused around the third target information. For example, when the second target information is new, the second target information is compared and fused to the third target information when the fusion is performed by processing the third target information and the comparative target fusion. Create a new one. In this case, the elements constituting the fourth target information are determined by operator selection using the second target information and the third target information. Also, when the second target information or the third target information is updated during the comparison fusion process, the process of releasing the comparison fusion may be performed similarly to the fusion unit.

The target processor 130 receives the fourth target information that is the result of the processing of the comparison fusion unit and performs various processes. The first target information and the second target information may include an orientation target in addition to the point target, and the orientation target is input to the target processing unit as the fourth target information while maintaining the original state since the fusion processing and the comparative fusion processing are not performed. The target processing unit generates the fifth target information by performing at least one of an association process, an association process, a pairing process, and an orientation cross measurement process on the point target in which the orientation target and the fusion process and the comparative fusion process are normally performed. In some cases, the fourth target information may be generated as the fifth target information as it is. Which manner of processing is to be performed may be selected by the operator of the target management device.

According to association processing or combining processing, some of the targeted fourth target information may not be able to maintain its own information. In this case, it is a problem when the original fourth target information needs to be recovered and used later when the association or binding relationship is released.

The same problem applies to the first target information, the second target information, and the third target information. In detail, the second target information or the third target information that is compared with the target of the user being fused among the first target information is not fused to other target information to maintain its own target information.

In such a case, when the release of various processes performed by the target processing unit, release of fusion performed by the target fusion unit, or comparative fusion release are performed, the previous target information should be restored. For this purpose, the target management device may include a storage unit storing each target information. It may further include.

Specifically, the target management apparatus includes a raw target information storage unit for storing the first target information, a system target information storage unit for storing the second target information and the fourth target information, and a tactical target information storage unit for storing the fifth target information. And a controller configured to determine a state of the first target information and the third target information and to cause the target fusion unit to perform at least one of generation, update, and deletion of each target information stored in each target information storage unit according to the identified state. It may further include. At this time, the original target information storage unit, the system target information storage unit and the tactical target information storage unit may be integrally formed.

In addition, the system target information storage unit may further store the third target information. In some cases, the third target information may be stored in a separate storage unit provided in the third target acquisition unit. In this case, the storage unit separately provided in the third target acquisition unit is also included in the system target information storage unit.

According to the above, the first target information and the third target information obtained in the target information acquisition step, the second target information generated in the fusion step, the fourth target information generated in the comparative fusion step, association processing, combining processing, pairing ( When the fifth target information generated in the pairing) processing and azimuth cross-section is distributed and stored in different storage units, the first target information to the fifth target information can be reliably extracted from each storage unit when it is necessary to later recover or use the target information. Can be used.

In addition, the target information may be stratified based on a storage unit in which the target information is stored. Specifically, the first target information stored in the raw target information storage unit may be stored in the original target layer, the second target information and the fourth target information (which may include the third target information) stored in the system target information storage unit may include the system target layer, the above-mentioned. The fifth target information stored in the target information storage unit may be classified into a tactical target layer and classified. Based on this, a method of generating, updating, and deleting target information can be considered. In addition, by presenting a variety of processing methods performed in the target layer fusion processing, comparative fusion processing, target processing unit to maintain a single target information even if the target information is received from a plurality of detection sensors and communication networks for one detection object. have.

For example, when the state of the first target information and the third target information is newly identified, the controller may allow the first target information to the fifth target information to be newly stored for each storage unit. If the state of the first target information and the third target information is determined to be updated, the controller may update and store the first target information to the fifth target information for each storage unit. The controller may be configured to delete the first target information to the fifth target for each storage unit when the state of the first target information and the third target information is determined to be deleted.

Among the states of the first target information and the third target information, the states of new, updated, and deleted can be grasped during the fusion process and the comparative fusion process by the target fusion unit, and the operator can recognize them through the display unit. The status of new, update and delete can be made at the request of the operator. If the new, updated or deleted status is by the operator, the operator should be able to clearly recognize the subject of the new / update / delete. By representing the first target information to the fifth target information with the original target layer, the system target layer, and the tactical target layer, the efficiency of the target management system can be attained. The third target information may be regarded as primitive acquisition of the target information like the first target information, but the third target information is processed by the other target management device to the position of the tactical target layer and is received through the communication network. It was classified as a system target layer one level lower than the layer. Accordingly, the third target information may be classified into the original target layer and stored in the original target information storage, or may be classified into the tactical target layer and stored in the tactical target information storage, which is determined by the operator.

FIG. 2 may be described as the operation of the target management device shown in FIG. 1.

First, the first target information is obtained from the detection sensor (S 510). Acquire a point target or azimuth target from the detection sensor. When the first target acquisition unit is integrally formed in the fusion unit 111 by the operation performed in the first target acquisition unit 20, the target management unit may be performed.

The first target information and the past second target information is fused to generate second target information (S520). The result of the fusion process by the operation performed in the fusion unit 111 includes both the case of fusion and the case of not fusion. When the convergence is not performed, the first target information and the past second target information are different targets, and thus the convergence is not possible, or the first target information or the past second target information is an azimuth target.

In operation S530, the second target information and the third target information acquired from the communication network are compared and converged to generate fourth target information. The operation is performed in the comparison fusion unit 113. As a result of the comparative fusion process, there may be a case where the comparative fusion is not performed and the comparative fusion is not performed. When the comparative fusion is not performed, the first target information and the third target information may be information of different detection objects, or the first target information or the third target information may be azimuth target.

The fifth target information is generated by performing at least one of the association process, the combining process, the pairing process, and the azimuth cross-processing process of the fourth target information (S540). The operation is performed in the target processor 130. The fourth target information input to the target processing unit includes both a point target with a fusion or a comparative fusion or a point target and azimuth target without a fusion or a comparative fusion. The target processing unit performs association processing, combining processing, pairing processing, and azimuth cross-processing processing on the fourth target information to be finally displayed on the display unit, transmitted to the armed control unit, or transmitted to another target management device through a communication network. 5 Generate target information.

In detail, the fifth target information may be converted into a data format output from the display unit and transferred to the display unit (S550).

In addition, the fifth target information may be transmitted using the communication network (S560).

In addition, the fifth target information may be transmitted to the armed controller (S570).

To this end, the target processing unit may further include a data converting unit converting the fifth target information into a signal available from the display unit 30, the arming control unit 40, and the communication unit 50.
