Description

System and method for screening priority target to be struck

The present invention relates to a system and method for selecting a priority target to hit, and more particularly, to a system and method for selecting a priority target to quickly and accurately select a priority target from a plurality of targets.

Conventionally, in order to identify a target to be hit, an optical searcher such as RF or IIR has been mainly used. The target is identified with these optical devices, and based on the identified target information, a specific object is identified as a target and hit.

However, the conventional technology using an optical device has a problem in that a lot of time and resources are consumed when there are a large number of targets. This is because the process of individually designating and launching a target for each of a plurality of targets in the process of confirming and striking a target must be repeatedly performed until all targets are processed.

In particular, in areas where there are many local provocations, there may be a case where the enemy provocations with a large number of weapons and resources, and the need to strike the enemy's weapons and resources quickly and accurately is more prominent.

Referring to FIG. 4 , first, image information 10 is acquired as a plurality of frames using the optical device 110 (S110).

Next, in order to identify a target in each image information 10, the number of clustered pixels is compared with the reference value th1 (S120).

As a result of the comparison, if the number of pixels is smaller than the reference value, the previous step (S120) is repeated for other clustered pixels.

As a result of the comparison, if the number of pixels is greater than the reference value, it is recognized that this clustered pixel is a target, and in the next step, it is determined whether the target is an enemy group or a friend group (S130).

Here, in order to distinguish whether the target is friendly or enemy, the enemy may be distinguished using, for example, a known Mode-4 or Mode-5 identification device (IFF).

Thereafter, a target platform analysis step (S140) and a target terrain analysis step (S150) are performed on the target recognized as an enemy group.

Here, the target platform analysis step (S140) is a step of analyzing whether the target platform recognized as an enemy is a ground, air, or sea platform, and the target terrain analysis step (S150) is a step of analyzing the location of the target or the type of terrain. , a detailed description of this will be given later.

After the platform analysis (S140) and terrain analysis (S150) for the target are completed, it is checked whether the acquired target and target information are all displayed on the tactical map (S160). As a result of the check, if all targets and target information are not displayed, the image information acquisition step (S110) of obtaining new image information (20) to this step (S160) are performed again. That is, taking the embodiment of FIG. 2 as an example, the above steps (S110 to S160) are performed a total of six times until the first target 20 and target information extracted from the six pieces of image information 20 are displayed through this step. ) is repeated.

In the embodiment of the present invention, all targets and target information are displayed on the tactical map, and then the target tactics are analyzed based on the results of the target platform analysis (S140) and the target terrain analysis (S150) (S170). Here, the target tactic may be an attack target of the target, a movement path, and the like.

Thereafter, information obtained through target platform analysis (S140), target terrain analysis (S150), and target tactics analysis (S170) is integrated and transmitted to the integrated entity (S180).

Thereafter, the threat level of the target is calculated based on the integrated information (S190), and a priority target is assigned based on the threat level (S210).

Referring to FIG. 6 , in the target terrain analysis step (S150), obtained image information (image_X _n ) may be input, and location point information of the target may be collected and output (S151). The position point information of the target that is output is, for example, contour line information (Point of Contour Line Information, P _{(CLI) n} ), coordinate information (Point of Coordinate Information, P _{(COI) n} ), distance information between the target and friendly forces ( Point of Distance Information, P _{(DI) n} ), and the like.

Next, ground type information (G _{(TYI) n} ) is estimated by FFT (Fast Fourier Transform) transform and filtering of image information (image_X _n ) (S153). Here, the terrain type information may be a highland, a lowland, etc., and since the risk level varies depending on the terrain type where the target is located, such information is extracted.

Next, after extracting a specific point of image information (image_X _n ), a feature vector value is generated from the center point to obtain ground vector information (G _{(VECI) n} ) (S155). Since the location of the target is relative, the location of the terrain is indicated as vector information based on the central point of the image information.

Next, location mapping data (MAP _n ) of image information (image_X _n ) is extracted using the formation information for each target unit (S157). A plurality of image information (image_X _n ) can be merged into one image information by using the mapping data (MAP _n ).

Referring to FIG. 9, in the target threat calculation step (S190), first, based on the integrated target information (TIC) obtained in the previous step, the target information integration step (S180), the location information of the current target (for example, the target's When terrain vector information (TG _(VECI)n [COORD. _Present ]) is input, the position information of the previous target (TG _(VECI)n [COORD. _old ]) and the updated position information of the new target after that point in time The movement information (TM _n ) of the target is calculated using the difference of (TG _{(VECI) n} [COORD. _new ]) (S191). This movement information is stored in real time.

Thereafter, the movement information (TM _n ) of the target is compared with the friendly threat evaluation information (oft) to evaluate whether the movement (ie, tactics) of the target poses a threat to the friendly army (S193).

As a result of the evaluation, if the threat level is lower than the alarm threshold value (alarm), that is, if it is determined that there is no threat, the previous step (S191) is performed for another target.

As a result of the evaluation, if the threat level is higher than the alarm threshold, it is determined that there is a threat and an alarm is generated to warn allies. At this time, the threat level may be derived as ranking of priority attack target.
