FIG. 1 is a diagram schematically illustrating a target generation operation according to an exemplary embodiment of the present invention, and FIG. 2 is a block diagram of a target processing apparatus using detection information of a pia identifier according to an exemplary embodiment of the present invention. Drawing.

As shown in FIG. 1, the method for generating a target according to the present invention sets a target moving speed, a direction-based current position prediction, and a target target range for each target over time, and generates a candidate target. The target is generated by accumulating the penalty for each candidate target and selecting a minimum penalty target at a predetermined time interval.

In other words, the target generation is generated by generating a plot list and a target list and then extracting tracking targets (minimum penalty targets) from the target list through collection, processing, and purification.

This operation will be described in detail with reference to FIGS. 2 to 4.

Referring to FIG. 2, a target processing apparatus using detection information of a PIA identifier according to an exemplary embodiment of the present invention may include a detection apparatus 100, a targeting apparatus 200, a engagement device 300, and an operator system 400. It may include. Here, the targeting device, which is a core technical idea of the present invention, may include a collecting unit 210, a processing unit 220, and a purification unit 230.

The detection apparatus 100 detects a target according to a set period using a radar or the like, and provides the detected detection information to the targeting apparatus 200. Here, the detection apparatus 100 is generally known in the art and will not be described in detail.

The targeting apparatus 200 collects plot information by using the detection information provided from the detection apparatus 100, processes the plot list by using the collected plot information, and then refines the processed plot list to obtain final Create a target list.

The targeting device 200 provides the finally generated target list to the engagement device 300 and the operator system 400 so as to utilize them in the engagement operation, and displays a reliable target list on the screen to the operator. It can be used for operation. Here, operations of the engagement device 300 and the operator system 400 are known in the art, and thus detailed description thereof will be omitted.

Hereinafter, the specific operation of the targeting device 200 which can be referred to as a core technical feature of the present invention will be described.

First, the collection unit 210 of the targeting apparatus 200 collects detection information (Plot information) provided from the detection apparatus 100. Here, the plot information provided from the detection apparatus 100 includes location information of each plot. That is, the collection unit 210 performs latitude and longitude coordinate transformation on the position information of each plot received from the detection apparatus 100, generates a list for each plot, and then stores the generated plot list. The generated plot list is provided to the processor 220. In this case, the operation is performed periodically according to the radar detection cycle to update the plot list.

The processor 220 may be largely composed of three steps, and the first operation may be divided into an operation of generating a target candidate group, a second operation of generating a new target, and a third operation of deleting an inactive target. .

Looking at the operation of generating the target candidate group, which is the first operation in the processor 220, first predicts and analyzes the current position range of each target in the previously generated target list, and each plot of the plot list is the predicted and analyzed current. Determine if it is within the location range.

As a result of determination, when the plot is within the predicted current position range, the processor 220 generates a candidate target by adding a plot to the target.

When the candidate target is generated, the processor 220 calculates a penalty for the targets (candidate group targets). In this case, the penalty may be calculated using a distance to the target, a moving direction, a speed, and the like.

As described above, when a penalty is calculated for each candidate target, the second operation of the processor 220 is performed to generate a new target. That is, it is determined whether a new plot is added as a target, and if a new plot is not added as a target, the corresponding plot is determined as the final target and added to the target list.

Subsequently, the processor 220 performs an operation of deleting the inactive target. First, in the state where a new target is generated and updated in the target list, it is determined whether information on the target is updated. That is, if the target information is not updated because the change in the moving speed, direction, and distance of the target does not occur, it is determined whether the corresponding non-update time exceeds the set time.

If the target is not updated within the preset time, the processor 220 deletes the target from the target list.

When the target list is generated through the processing of the plot list as described above, the target list information is provided to the refiner 230. Here, the target list information may include at least one or more information of ID information, distance information, speed information, moving direction information, and current location information of the corresponding target. In addition, since the information is updated regardless of whether the target is activated in the target list, a target having the same ID may exist in the updated list, and thus, a purification process of the target is required. That is, the target list may include both the start target and the stop target list.

The refiner 230 refines the target list at a predetermined cycle, and first, determines whether the preset purification cycle has been reached.

When the purification cycle is reached, the purification unit 230 selects the same ID target from the target list, calculates the penalty of the targets having the same ID selected, and selects the target having the minimum penalty.

Then, the final target list is generated by purifying the target list by deleting the targets except for the target having the least penalty.

When the final target list is generated as described above, the generated final target list is provided to the engagement device 300 and the operator system 400.

The engagement device 300 utilizes the target list provided from the targeting device 200 for engagement operation, and the operator system 400 displays the target list provided from the targeting device 200 on the display device to the operator. It provides reliable target information.

Here, the steps S312 to S313 are periodically performed according to the radar detection cycle to update the plot list (S320).

As such, when the plot list is generated and stored, the plot list processing step S330 is performed.

Referring to FIG. 4 with respect to the plot list processing step S330, first, the plot list processing step may be divided into generating a target candidate group, generating a new target, and deleting an inactive target. have.

First, referring to the operation of generating the target candidate group, the current position range of each target is predicted and analyzed in the previously generated target list (S331).

Next, it is determined whether each plot of the plot list is located within the analyzed predicted range (S332).

As a result of the determination, when the plot is within the analyzed range, the candidate target is generated by adding plot (p) to the target t (S333).

When the candidate target is generated, a penalty is calculated for the targets (candidate group targets) (S334). In this case, the penalty may be calculated using a distance to the target, a moving direction, a speed, and the like.

When the penalty is calculated for each of the candidate targets as described above, the operation of generating a new target is performed.

First, it is determined whether a new plot has been added as a target (S335).

As a result of determination, when a new plot is not added as a target, the plot is determined as a final target and added to the target list (S336).

Thereafter, the step of deleting the inactive target is performed. First, in the state in which a new target is generated and updated in the target list, it is determined whether information on the target is updated (S337). That is, when the target information is not updated because the change in the moving speed, the direction, and the distance of the target does not occur, it is determined whether the corresponding non-update time exceeds the set time (S338).

If the target is not updated for a predetermined time, the target is deleted from the target list (S339).

When the target list is generated through the processing of the plot list as described above, an operation of purifying the target list is performed. Here, the target list information may include at least one or more information of ID information, distance information, speed information, moving direction information, and current location information of the corresponding target. In addition, since the information is updated regardless of whether the target is activated in the target list, a target having the same ID may exist in the updated list, and thus, a purification process of the target is required. That is, the target list may include both the start target and the stop target list.

Referring to the operation of the purification step of the target list, as shown in FIG. 3, first, by refining the target list at a predetermined cycle, first, it is determined whether the preset purification cycle has been reached (S340).

When the purification cycle is reached, the same ID target is selected from the target list (S351), the penalty of the targets having the selected same ID is calculated, and the target having the minimum penalty is selected (S352).

Thereafter, by deleting the targets other than the target having the minimum penalty (S353), the final target list is generated through the refinement of the target list, and then the penalty calculation is initialized (S354).

When the final target list is generated as described above, the generated final target list is provided to the engagement device and the operator system.

The engagement device utilizes the target list provided from the targeting device for engagement operation, and the operator system displays the target list provided from the targeting device on the display device to provide reliable target information to the operator.
