Description

Multifunctional radar device and its resource management method{MULTIFUNCTION RADAR AND RESOURCE MANAGING METHOD OF THE SAME}

The present invention relates to a multi-function radar device and a resource management method thereof, and more particularly, to a multi-function radar device capable of efficiently managing resources of a plurality of multi-function radar devices and a resource management method thereof.

In general, a multi-function radar can perform several functions, such as navigation, general tracking, and precise tracking. In particular, the active phased array radar can be used as a multi-function radar because it can steer the beam electronically in a very short time. The active phased array radar can perform multiple tasks (or resources) sequentially while rapidly adjusting the beam direction.

At this time, since the active phased array radar needs to perform various tasks, the order in which tasks are performed needs to be managed. Therefore, in the prior art, a list of tasks to be performed by the active phased array radar was prepared in advance, and then the active phased array radar performed the tasks in the order of the list.

Recently, a plurality of active phased array radars are installed and used together to effectively search and track targets. Accordingly, while the regions in which the active phased array radars emit beams partially overlap, it is possible to perform the same task for one target generated in an area where a plurality of active phased array radars overlap. Accordingly, there is a problem in that the duties of the active phased array radars are overlapped, and thus the duties are inefficiently managed.

However, the present invention is not limited to the embodiments disclosed below, but will be implemented in various different forms, and only these embodiments allow the disclosure of the present invention to be complete, and the scope of the invention to those skilled in the art is completely It is provided to inform you. To describe the invention in detail, the drawings may be exaggerated, and the same reference numerals in the drawings refer to the same elements.

Hereinafter, a multifunctional radar device according to an embodiment of the present invention will be described.

The multi-function radar device according to an embodiment of the present invention may be a multi-function radar device capable of performing various functions such as searching for a target, general tracking for tracking a target's position, and precision tracking for precisely tracking a target's position. have. Referring to FIG. 1, the multi-function radar device 1000 includes a plurality of multi-function radars 100, a plurality of resource management units 200, a detection unit 300, and a processing unit 400.

The multi-function radar 100 may include a plurality of antennas 110 and a plurality of transmission/reception modules 120. The antennas 110 may be arranged according to a predetermined pattern, and the transmission/reception modules 120 may be connected to each of the antennas. Therefore, the direction of the multi-function radar 100 can be adjusted by directly controlling the phase of the antennas 110 in a digital manner. At this time, the multi-function radar 100 may be an active phased array radar.

In addition, a plurality of multi-function radar 100 may be provided. When a plurality of multi-function radars 100 are provided, a range capable of performing a task or a wavelength band used by the multi-function radars 100 may be increased. Accordingly, regions in which the multi-function radars 100 emit beams may overlap each other. Therefore, a plurality of multi-function radars 100 for the same target can perform the same task.

For example, as shown in FIG. 2(a), four multi-function radars 100 may be provided. Since the multi-function radars 100 are arranged on four sides to face different directions, they can be connected to each other to form a four-sided radar. The length of each multi-function radar 100 emitting a beam is longer than the length of each surface. Therefore, a region where beams are radiated may be partially overlapped at corner portions where the multi-function radars 100 are connected to each other. Accordingly, when a target is detected in the overlapping region A, two multi-function radars 100 connected to each other may perform a task overlapping each other.

Or, as shown in Figure 2 (b), the multifunction radar 100 may be provided with two. Since the multi-function radars 100 are arranged to be connected in the same direction with different wavelength bands, a dual band radar can be formed. Since the multi-function radars 100 face the same direction, the regions where the two multi-function radars 100 emit beams may overlap each other. Therefore, when a target is detected in the overlapping area A, the multi-function radars 100 may perform a task overlapping each other. However, the number or arrangement of multi-function radars 100 is not limited to this and may be varied.

At this time, the multi-function radar 100 may be installed on the ship. In particular, since a warship needs to acquire location information of various targets such as a missile, an aircraft, and an enemy warship, it is possible to find various targets in a wide area with multi-function radars 100 and obtain location information of targets.

As illustrated in FIG. 1, a plurality of resource management units 200 may be provided as many as the multifunction radar 100 is provided. The resource management units 200 may be connected to send and receive signals with each of the multi-function radars 100. Accordingly, the resource management units 200 may wait for tasks to be performed on each of the multi-function radars 100 and then deliver them. Referring to FIG. 3, the resource management unit 200 may include an input module 210, a delivery module 220, and a standby module 230.

A plurality of tasks to be performed by the multifunction radar 100 may be input to the input module 210. The number or type of tasks input to the input module 210 may be changed according to changes in the surrounding environment of the multifunction radar 100. For example, when a target is detected by the multi-function radar 100 that has performed a detection function for finding a target, it is necessary to perform a task of tracking the target. Therefore, the task of tracking the target may be suddenly added to the input module 210.

At this time, the tasks may be repeatedly performed at different cycles for a predetermined time. In the case of the mission to track the target, it is necessary to periodically check the changing position of the target by emitting an electron beam to the target periodically. That is, the position information of the target is continuously updated by emitting an electron beam at a predetermined number of times for a predetermined time.

For example, when performing a task of tracking two targets, the target of a relatively important target is more precisely identified by increasing the number of times the electron beam is emitted for a certain period of time (or by increasing the update rate), For a relatively insignificant target, the position of the target can be roughly confirmed by reducing the number of times the electron beam is emitted for a certain period of time (or by reducing the update rate). Therefore, when performing a task of tracking two targets, a point in time in which the radiation of the electron beams overlaps in the two tasks may occur because the update rates of the two tasks are different. Since one multi-function radar 100 can perform only one task at a time, when the time when the two tasks are overlapped, one task may not be performed.

The delivery module 220 is connected to send and receive signals to and from the input module 210. The delivery module 220 may deliver a task input to the input module 210 to the multifunction radar 100. Accordingly, the multi-function radar 100 may perform a task by adjusting the shape or cycle of the beam emitted according to the task delivered by the delivery module 220. Therefore, a beam suitable for each task can be emitted.

The standby module 230 is connected to send and receive signals between the input module 210 and the delivery module 220. Thus, before the tasks input to the input module 210 are delivered to the delivery module 220, the standby module 230 may wait.

At this time, the standby module 230 may classify tasks into different priority tables (or queues) according to the function of the multifunction radar 100. Tasks can be queued to each table in the order in which they are entered. The standby module 230 may deliver tasks to the delivery module 220 according to the priority of the tables.

For example, if the multi-function radar 100 has the functions of search, general tracking, and precision tracking, the standby module 230 may search tasks 233, the general tracking table 232, and the precision tracking table 231. ). When the tasks of two or more tables of the search table 233, the general tracking table 232, and the precision tracking table 231 overlap, the standby module 230 compares which task has the highest table priority and prioritizes it. It can be delivered to the delivery module 220 from the mission of the table with a high rank. Therefore, even if the times in which the tasks of the different tables overlap, the tasks of the high priority table can be performed stably.

Referring to FIG. 4, the sensing unit 300 is connected to send and receive signals with a plurality of resource management units 200. Accordingly, the sensing unit 300 may detect overlapping overlapping missions among tasks waiting in different resource management units 200. The detector 300 includes a detector 310 and a sorter 320.

The detector 310 may compare tasks waiting for different resource management units 200. Therefore, it is possible to check whether duplicate missions to the same target have occurred in the resource management units 200. That is, it may be confirmed whether a task of tracking targets overlapping with the resource management units 200 has occurred.

For example, the detector 310 may compare targets of missions waiting for the resource management units 200. Accordingly, if a task for the same target is waiting for different resource management units 200, the detector 310 may determine that a duplicate mission has occurred.

The selector 320 is connected to send and receive signals with the detector 310. Accordingly, when the detector 310 confirms the occurrence of a duplicate mission, the selector 320 may select resource managers having duplicate missions from other resource managers from among the entire resource managers 200.

The processing unit 400 is connected to send and receive signals to and from the sensing unit 300. When the sensing unit 300 detects a duplicate mission, the processing unit 400 may delete a duplicate mission waiting for some of the resource managers having the duplicate mission. Accordingly, it is possible to prevent the plurality of multifunction radars 100 from performing the same overlapping mission. The processing unit 400 may include an order comparator 410 and a processor 420.

The sequence comparator 410 is connected to send and receive signals to and from the selector 320. The order comparator 410 may compare the order in which the duplicate missions are waiting in each of the resource management units 200 selected by the sorter 320.

For example, a duplicate mission may occur in the resource management unit 1 connected to the multifunctional radar 1 and the resource management unit 2 connected to the multifunctional radar 2. The sequence comparator 410 may check the number of overlapping tasks among the tasks waiting for the resource management unit 1 and the number of duplicate tasks among the tasks waiting for the resource management unit 2. Accordingly, the sequence comparator 410 may check which resource management unit of the first resource management unit or the second resource management unit can perform a duplicate mission first.

The processor 420 is connected to send and receive signals with the sequence comparator 410. The processor 420 maintains the overlapping mission of the resource management unit capable of delivering the duplicated mission to the multifunction radar first among the resource management units selected by the sorter 320 and deletes the duplicated missions of other resource management units.

For example, if the order in which the duplicate missions are waiting in the resource management unit 1 is the first and the sequence in which the duplicate missions is waiting in the resource management unit 2 is the second, the sequence comparator 410 is the duplicate mission in the resource management unit 1 , It can be judged that it can be performed before the duplicated task of the resource management department No. 2. Accordingly, the processor 420 may maintain a duplicate mission waiting for the resource management unit 1 and delete the duplicate mission waiting for the resource management unit 2. Accordingly, the overlapping mission can be quickly performed without being duplicated.

Meanwhile, the processing unit 400 may include a task amount comparator (not shown) and a processor 420. At this time, when the processing unit 400 is provided with a task comparator, the sequence comparator 410 may not be provided.

The duty comparator is connected to send and receive signals to and from the selector 320. The task quantity comparator may compare the task quantity (or the number of tasks) waiting in each of the resource management units 200 selected by the selector 320.

For example, a duplicate mission may occur in the resource management unit 1 connected to the multifunctional radar 1 and the resource management unit 2 connected to the multifunctional radar 2. The task comparator can check how many tasks are waiting in the resource management unit 1 and how many tasks are waiting in the resource management unit 2. Accordingly, the task comparator can check which resource management unit among the resource management unit 1 and the resource management unit 2 has a margin to perform a duplicate mission.

The processor 420 is connected to send and receive signals with the duty comparator. The processor 420 may maintain the overlapping mission of the resource management unit having the smallest mission among the resource management units selected by the sorter 320 and delete the duplicate missions of other resource management units.

For example, if there are two tasks waiting for the resource management unit 1 having a duplicate mission and three tasks waiting for the resource management unit 2, the task amount comparator is more redundant than the resource management unit 1 and the resource management unit 2 You can judge that you have room to perform. Accordingly, the processor 420 may maintain a duplicate mission waiting for the resource management unit 1 and delete the duplicate mission waiting for the resource management unit 2. Accordingly, the overlapping mission can be stably performed without being duplicated.

At this time, if there are too many tasks waiting for one resource management unit 200, the time at which the tasks are performed may overlap with each other. Since the multi-function radar 100 performs only one task for a certain period of time, any one of tasks with overlapping execution times may not be performed. Accordingly, when a duplicate mission occurs, the duplicate mission can be deleted in the resource management unit having a relatively large number of missions, and the duplicate mission can be maintained in the resource management unit having a relatively small number of missions. Accordingly, the resource management unit having a relatively large number of missions can stably perform waiting tasks, and the resource management unit having a relatively small number of missions can stably perform redundant tasks.

Meanwhile, the processing unit 400 may further include an importance comparator 430 and an order adjuster 440. At this time, the processing unit 400 may include a processor 420 together with any one of an order comparator 410 and a task amount comparator.

The importance comparator 430 is connected to send and receive signals with the processor 420. Accordingly, the importance comparator 430 may check the resource management unit in which the duplicate mission is maintained among the resource management units having the duplicate mission. The importance comparator 430 may compare the importance of a duplicate task and a preceding task waiting in front of the duplicate task in the resource management unit where the duplicate task is maintained.

At this time, the importance of the mission may be determined according to the type of target. Therefore, the importance comparator 430 can compare the types of targets and compare the importance of the overlapping task and the preceding task.

The sequence adjuster 440 is connected to send and receive signals with the importance comparator 430. If the importance comparator 430 determines that the overlapping task has a higher importance than the preceding task, the order adjuster 440 may adjust the order in which the overlapping task and the preceding task wait. Accordingly, the overlapping mission may be delivered to the multifunction radar 100 prior to the preceding mission. Therefore, even if the overlapping task and the time during which the preceding task are performed overlap, a task having high importance can be stably performed.

As described above, tasks performed by the plurality of multi-function radars 100 may be managed so as not to overlap. Accordingly, it is possible to prevent the multi-function radars 100 from performing the same task for the same target. Therefore, by efficiently managing the tasks performed by the multi-function radar 100, the multi-function radar 100 can more effectively search for and track the target.

5 is a view showing the structure of a multi-function radar device according to another embodiment of the present invention. Hereinafter, a multifunctional radar device according to another embodiment of the present invention will be described.

The multi-function radar device according to another embodiment of the present invention may be a multi-function radar device capable of performing various functions such as searching for a target, general tracking to track the target's position, and precise tracking to precisely track the target's position. have. Referring to FIG. 5, the multi-function radar apparatus 1000 includes a plurality of multi-function radars 100, a plurality of resource management units 200, a detection unit 300, a determination unit 500, and a processing unit 400.

At this time, the multi-function radar device according to an embodiment of the present invention, the multi-function radar 100, the resource management unit 200, and the detection unit 300 provided in the multi-function radar device according to another embodiment of the present invention have the same structure With, you can play the same role. Therefore, the description of the multi-function radar 100, the resource management unit 200, and the detection unit 300 will be omitted.

The determination unit 500 is connected to send and receive signals to and from the detection unit 300. The determination unit 500 may determine the importance of the overlapping mission detected by the detection unit 300. The determination unit 500 includes a target confirmer 510 and a determiner 520.

The target confirmer 510 may check the type of the target of the overlapping mission. The target confirmer 510 may confirm the type of target using information such as the size and speed of the target.

The determiner 520 is connected to send and receive signals with the target confirmer 510. The determiner 520 may determine the importance of the overlapping mission up or down according to the type of target. The determiner 520 may determine that the overlapping mission for a relatively high target has a high importance, and the overlapping mission for a relatively low target has a low importance. Therefore, a duplicate mission with high importance may be judged as high, and a duplicate mission with low importance may be judged as low.

The processing unit 400 is connected to send and receive signals to and from the determination unit 500. The processing unit 400 may delete the duplicate mission from some of the resource management units having the duplicate mission, according to the determination of the judgment unit 500. The processing unit 400 includes a first processor 421 and a second processor 422.

When the importance of the duplicated task is determined to be different, the first processor 421 may maintain the duplicated task in all resource management units having the duplicated task. Accordingly, the resource management units 200 may transmit the overlapping tasks to the multifunction radars 100, so that the multifunction radars 100 may perform the overlapping tasks. Therefore, a plurality of multi-function radars 100 perform a high-priority overlapping mission together, so that it is possible to acquire location information for a high-priority target in more detail.

When the importance of the duplicated task is determined to be low, the second processor 422 may delete the duplicated task from some of the resource management units having the duplicated task. Accordingly, it is possible to prevent the plurality of multi-function radars 100 from performing the same overlapping mission with low importance. The second processor 422 includes a comparison module and a deletion module.

The comparison module is connected to send and receive signals to and from the selector 320. The comparison module may compare the number of tasks of each of the resource management units 200 selected by the selector of the detection unit 300.

The deletion module is connected to send and receive signals to and from the comparison module. The deletion module may delete duplicate missions from the resource management unit having more tasks among the resource management units selected by the selector. Accordingly, in the multi-function radar 100 having a relatively large number of missions, the overlapping mission may not be performed repeatedly, and relatively, the margin may be stably performed in the multi-function radar having a margin in the number of missions. However, the present invention is not limited thereto, and various combinations between embodiments are possible.

As described above, the plurality of multi-function radars 100 may selectively perform the same overlapping mission according to the importance of the target. Accordingly, for a target having high importance, a plurality of multi-function radars 100 perform a tracking task together, so that the target can be more accurately and accurately tracked. For a low-importance target, only one multi-function radar 100 among a plurality of multi-function radars 100 performs a tracking task, and the other multi-function radar 100 can stably perform other tasks. Therefore, it is possible to efficiently manage the tasks performed by the multi-function radars 100.

6 is a view showing a resource management method according to an embodiment of the present invention, Figure 7 is a standby module in accordance with an embodiment of the present invention to select the standby module to delete the duplicated task in the order of waiting for duplicated tasks 8 is a diagram illustrating a process of selecting a standby module to delete a duplicate mission according to a waiting amount in a standby module according to an embodiment of the present invention. Hereinafter, a resource management method according to an embodiment of the present invention will be described.

The resource management method according to an embodiment of the present invention is a resource management method for managing a task of a multi-function radar device having a plurality of multi-function radars that are arranged to be connected in the same direction with different wavelength bands. Referring to FIG. 6, the resource management method is a process of classifying tasks to be performed by each of the multi-function radars and waiting them in different resource management units (S110), overlapping overlapping tasks among tasks waiting for different resource management units It includes the process of confirming whether or not the occurrence of the duplicated task (S120), and when the occurrence of the duplicated task, deleting some of the duplicated tasks waiting for different resource management units (S130).

At this time, the resource management method according to an embodiment of the present invention may be performed by being applied to the multifunction radar device 1000 according to an embodiment of the present invention of FIGS. 1 to 3. A plurality of tasks to be performed by the multifunction radar 100 may be input to the input module 210 of the resource management unit 200. The task may be input to the input module 210 according to the surrounding environment. For example, when a target is detected by the multi-function radar 100 performing a detection task of finding a target, it is necessary to perform a detection task and a task of tracking the target together. Therefore, only a detection task is input to the input module 210, and a task for tracking a target may be suddenly added.

Meanwhile, resources such as radio resources (frequency, time), antenna resources (sub-array), system resources (power), and processing resources (CPU, memory, etc.) are physically distributed and operated in order to perform the task. Accordingly, since the mission includes information for operating various resources, the mission may be a resource.

Then, the tasks input to the input module 210 may be queued in order to different standby modules 230 according to the type of function performed by the multifunction radar 100. For example, if the multi-function radar 100 can perform three functions such as precision tracking, general tracking, and searching, the standby module 230 may include a precision tracking table 231, a general tracking table 232, and Three tables, such as the search table 233, may be provided. Accordingly, tasks may be classified into one of the search table 233, the general tracking table 232, and the precise tracking table 231 according to the type. However, the type of the table is not limited to this, and the number and type may vary depending on the function of the multi-function radar 100.

In this case, a plurality of multi-function radars 100 may be provided, and a plurality of resource management units 200 may also be provided to be connected to each of the multi-function radars 100. Accordingly, tasks to be performed by each of the multi-function radars 100 may be queued to different resource managers 200, and tasks may be classified in each resource manager 200 to be queued in order from different tables. .

In addition, since a plurality of multi-function radars 100 are provided, regions where the multi-function radars 100 emit beams may overlap each other. Accordingly, when a target is generated in an overlapping region, overlapping duties for the same target may be input to the resource management units 200. Therefore, there is a need to improve the efficiency of resource management by managing redundant tasks.

First, it is possible to check whether duplicate missions have occurred among tasks waiting for different resource management units 200. To this end, it is possible to compare the targets of the missions waiting for different resource management units 200 to determine whether a duplicate mission has occurred. Therefore, if the missions for the same target are waiting for the different resource management units 200, the detector 310 may determine that a duplicate mission has occurred.

Then, when the occurrence of the overlapping task is confirmed, resource managers having a duplicate mission among the entire resource managers 200 may be selected from other resource managers. Therefore, it is possible to check which resource management units 200 have a duplicate mission.

When the occurrence of a duplicate mission is confirmed, some of the duplicate missions waiting for different resource management units may be deleted. Accordingly, except for a duplicate mission waiting for one of the resource managers having the duplicate mission, the duplicate mission waiting for the remaining resource managers may be eliminated. Therefore, only one multifunction radar 100 can perform the overlapping mission.

For example, it is possible to compare the order in which the overlapping missions wait in each of the selected resource management units. When a duplicate mission occurs in the resource management unit 1 connected to the multifunctional radar 1 and the resource management unit 2 connected to the multifunctional radar 2, the standby module 230a of the resource management unit 1 as shown in FIG. In the second waiting module 230b of the second resource management unit, the order in which the redundant mission P waits may be compared. If the overlapping mission P waits first in the standby module 230a for the first time and the overlapping mission P waits for the second time in the standby module 230b for the second time, the overlapping mission for the standby module 230a for the first waiting time 230a. It can be determined that (P) is waiting in front of the overlapping mission P of the second waiting module 230b.

Then, among the selected resource managers, the duplicate mission of the resource manager capable of delivering the duplicate mission to the multifunction radar is maintained first, and the duplicate missions of other resource managers can be deleted. When the overlapping mission P of the standby module 230a waits ahead of the overlapping mission P of the standby module 230b, the overlapping mission P of the standby module 230a is the current time. It can be performed immediately, the duplicated mission (P) of the second standby module (230b) can be performed after the preceding mission (S) is performed. Accordingly, the duplicate mission P of the standby module 230a can be maintained, and the duplicate mission P of the standby module 230b can be deleted.

That is, when a duplicate mission occurs, first, the duplicate mission can be maintained only in the task waiting unit capable of delivering the duplicate mission to the multi-function radar, and the duplicate management task can be deleted in the resource management unit having another duplicate mission. Therefore, the redundant mission can be stably and quickly performed, and the mission waiting unit in which the redundant mission is deleted can stably transfer other missions to the multi-function radar, so that the missions can be efficiently managed. Accordingly, a multi-function radar to perform the overlapping mission may be selected in the order in which the overlapping missions wait.

Alternatively, the waiting amount of each of the selected resource management units may be compared. When a duplicate mission occurs in the resource management unit 1 connected to the multifunctional radar 1 and the resource management unit 2 connected to the multifunctional radar 2, the standby module 230a of the resource management unit 1, as shown in FIG. 8, The waiting amount of each of the waiting modules 230b of the second resource management unit may be compared. If the total number of missions including duplicate missions (P) in the standby module (230a) 1 is two, and the total number of missions including duplicate missions (P) in the standby module (230b) 2 is three, wait 1 It can be determined that the task amount of the module 230a is less than that of the second standby module 230b.

Then, the overlapping mission of the resource management unit having the smallest mission among the selected resource management units may be maintained, and the overlapping mission of other resource management units may be deleted. When the task amount of the standby module 230a is less than the task quantity of the standby module 230b, the overlapping task P of the standby module 230a is not overlapped with the execution time of other preceding tasks S. It may not be stably performed, and the overlapping task P of the second standby module 230b may not be overlapped with the execution time of the first preceding task S1 or the second preceding task S2. Accordingly, the duplicate mission P of the standby module 230a can be maintained, and the duplicate mission P of the standby module 230b can be deleted.

That is, when a duplicate mission occurs, the duplicate mission is maintained only in the task waiting unit having the smallest amount of duties, and the resource management unit having another duplicate mission can delete the duplicate mission. Therefore, the redundant mission can be performed more reliably without overlapping with other missions by being performed in a multi-function radar that can afford to perform the mission, and the redundant mission is deleted in the standby unit where the redundant mission is deleted to stably multi-function other missions. Can be delivered to the radar. Therefore, a multi-function radar capable of performing the overlapping mission may be selected according to the duty amount.

On the other hand, after selecting the resource management unit to maintain the duplicate mission, it is also possible to adjust the order of the tasks in the resource management unit where the duplicate mission is maintained. For example, if there is a predecessor waiting in front of the duplicated task, the importance of the duplicated task and the preceding task can be compared. The importance of the mission can be determined by the type of target. Therefore, the importance of the overlapping task and the preceding task can be compared by comparing the types of targets of the overlapping task and the preceding task.

If it is determined that the overlapping task has a higher importance than the preceding task, the order in which the overlapping task and the preceding task are queued can be adjusted. Accordingly, the overlapping mission may move to the front of the preceding mission and wait, and the overlapping mission may be delivered to the multifunction radar 100 before the preceding mission.

If it is determined that the preceding mission is more important than the overlapping mission, the order in which the overlapping mission and the preceding mission are waiting may not be changed. Accordingly, the preceding mission may be delivered to the multifunction radar 100 prior to the overlapping mission. Therefore, even if the overlapping task and the time during which the preceding task are performed overlap, a task having high importance can be stably performed.

9 is a view showing a resource management method according to another embodiment of the present invention, Figure 10 is a view showing a process of maintaining a duplicate mission in the standby module according to an embodiment of the present invention. Hereinafter, a resource management method according to another embodiment of the present invention will be described.

The resource management method according to another embodiment of the present invention is a resource management method for managing a task of a multi-function radar device having a plurality of multi-function radars that are arranged to be connected in the same direction with different wavelength bands. Referring to FIG. 9, the resource management method is a process of classifying tasks to be performed by each of the multi-function radars and waiting them in different resource management units (S210 ), and overlapping duplicate tasks among tasks waiting for different resource management units (S220) to determine whether the occurrence of a duplicate mission occurs, when determining the importance of the duplicate mission (S230), and according to the importance of the duplicate mission, overlapping missions in some of the resource management units with duplicate missions It includes a process of deleting (S240).

At this time, the resource management method according to another embodiment of the present invention may be performed by being applied to the multifunction radar device 1000 according to another embodiment of the present invention of FIG. 5. In the resource management method according to an embodiment of the present invention, and the resource management method according to another embodiment of the present invention, a process of classifying tasks to be performed by each of the multi-function radars and waiting them in different resource management units, and different resources The process of checking whether duplicate overlapping tasks have occurred among the tasks waiting for the management departments may be performed in the same manner. Therefore, descriptions of the two processes will be omitted.

Meanwhile, resources such as radio resources (frequency, time), antenna resources (sub-array), system resources (power), and processing resources (CPU, memory, etc.) are physically distributed and operated in order to perform the task. Accordingly, since the mission includes information for operating various resources, the mission may be a resource.

When the occurrence of the overlapping mission is confirmed, the importance of the overlapping mission can be determined. The importance of the overlapping mission may be determined according to the type of target of the overlapping mission. When the type of the target is confirmed using information such as the size and speed of the target, the importance of the overlapping mission may be determined up or down depending on the type of the target. It can be judged that the overlapping mission for a relatively high-priority target has a higher importance, and the overlapping mission for a relatively low-priority target can be judged to have a lower importance. Therefore, a duplicate mission with high importance may be judged as high, and a duplicate mission with low importance may be judged as low. At this time, the criteria for determining the importance according to the type of target may be set in advance by the operator.

Then, depending on the importance of the duplicated task, the duplicated task may be maintained in all of the resource management units having the duplicated task, or the duplicated task may be deleted in part. Accordingly, a plurality of multi-function radars may perform the overlapping task together depending on the importance of the overlapping task, or only one selected multi-function radar may perform the overlapping task.

For example, if it is determined that the importance of the overlapping mission is different, the overlapping mission may be maintained in all resource management units having the overlapping mission. When a duplicate mission occurs in the resource management unit 1 connected to the multifunctional radar 1 and the resource management unit 2 connected to the multifunctional radar 2, the standby module 230a of the resource management unit 1, as shown in FIG. It is possible to maintain the overlapping mission P waiting at each of the second waiting module 230b of the second resource management unit.

At this time, in the first waiting module 230a, the overlapping mission P may wait first, and the subsequent mission T may wait a second time. In the second waiting module 230b, the preceding mission S may wait first, and the duplicate mission P may wait second. Accordingly, the overlapping mission P waiting in the standby module 230a may be performed before the overlapping mission P waiting in the waiting module 230b, and the two overlapping missions P are different. Can be done in time. Accordingly, a plurality of multi-function radars 100 perform a high-priority overlapping mission together at different times, so that it is possible to obtain location information for a high-priority target in more detail.

On the other hand, if the importance of the duplicated task is determined to be low, some of the resource management units having the duplicated task may delete the duplicated task. When a duplicate mission occurs in the resource management unit 1 connected to the multifunctional radar 1 and the resource management unit 2 connected to the multifunctional radar 2, the standby module No. 1 of the resource management unit 1 and the resource management unit 2 of the resource management unit 2 You can compare the number of waiting tasks in each waiting module. If the total number of missions including duplicate missions in standby module 1 is two, and the total number of missions including duplicate missions in standby module 2 is three, the number of missions in standby module 1 is the number of standby modules in standby module 2. It can be judged to be less than the number of missions.

Then, the overlapping mission of the resource management unit having the smallest number of tasks among the selected resource management units may be maintained, and the overlapping mission of other resource management units may be deleted. When the number of tasks of the standby module 1 is less than the number of tasks of the standby module 2, the overlapping task of the standby module 1 can be stably performed because the execution time does not overlap with other preceding tasks, and the standby module #2 The overlapping task of the first preceding task or the second preceding task may not be performed because the execution time overlaps. Therefore, the duplicated mission of the standby module 1 can be maintained, and the duplicated mission of the standby module 2 can be deleted. However, the method for selecting a standby module to which a duplicate mission is to be deleted is not limited to this and may be varied.

On the other hand, after selecting the resource management unit to maintain the duplicate mission, it is also possible to adjust the order of the tasks in the resource management unit where the duplicate mission is maintained. That is, when several missions are waiting in the resource management unit, the importance of the missions can be compared. Accordingly, if it is determined that the overlapping mission has a higher importance than other missions, the order of the overlapping missions may be changed in front of other missions having low importance. Therefore, even if the overlapping mission and the time when other tasks are performed overlap, the overlapping mission can be stably performed.

As described above, although specific embodiments have been described in the detailed description of the present invention, various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the claims to be described below, but also by the claims and equivalents.
