Description

[0001] METHOD AND APPARATUS FOR EVALUATING THREAT OF SURFACE TARGETS [0002]

The present invention relates to a technique for evaluating the threat of a land target, more particularly, to a threat of a land target capable of calculating the threat of each target based on the proximity of the target, armed assets, Evaluation method and apparatus thereof.

As is well known, in an environment where multiple armed assets are operated on multiple targets, it is very important to establish a fire plan to effectively defeat the target in a short time, and utilize the fire plan thus established in the operation.

In order to establish the shooting plan, it is essential to monitor and manage the targets and quantify the threats of the targets through various analyzes to prioritize the targets with high threats.

However, at present, there is only a threat assessment method for antiaircraft and anti-ship targets, and there is no threat evaluation method considering characteristics of land targets, especially plural target targets, There is a problem that it is not possible to apply the threat assessment method to the development of artillery weapons systems.

Here, in the threat evaluation method for existing antiaircraft targets, objects such as the position of the target, the movement speed of the target, the attack probability of the target derived based on the entry angle, the distance between the target and the asset, The threat assessment is performed based on the variables.

In addition, the threat evaluation method based on the existing antitank target evaluates the threat based on the object variables such as the position of the target, the speed of movement of the target, the distance to the nearest point of the target and the target, and the time of arrival.

However, the above-mentioned existing technology is a technique specialized in the air and the field, and thus it is not suitable to be applied to the threat detection of the earth target.

In other words, unlike the anti-aircraft and anti-aircraft fields, which consider the movement speed of the target and the arrival time of the target, the evaluation of the threat of the land target takes into account the inherent characteristics of the target range, the type of target, Though the threat evaluation method optimized for the land target is needed, at present, there is no model for evaluating the threat according to the characteristics of the land target.

Then, in the importance-based proximity calculator 114, the third proximity and the protection asset proximity calculator 113 calculated through the armed asset proximity calculator 112 using Equation (13) Also, the fifth proximity is calculated based on the relative importance of each armed asset and each protected asset (step 212).

Based on the fifth proximity computed by the importance-based proximity computation unit 114 and the weights according to the characteristics of each target, the threat level calculation unit 115 calculates the threat of each target using the equation (16) (Step 214).

Thereafter, in step 216, it is checked whether or not there is a target to be subjected to the threat calculation. If it is determined that there is a target to be calculated as a result of the check here, the process proceeds to steps 204 and 206 ), And repeat the subsequent steps.

For example, when it is assumed that there are N targets to be subjected to the threat evaluation, the processing of steps 204 to 214 is repeated N-1 times after starting the initial process.

As a result of the check in step 216, when it is judged that the target of the threat degree calculation does not exist (that is, it is judged that all the threats to the entire target to be subjected to the threat evaluation are calculated), the output unit 116 The threat level of each calculated target is calculated (quantified) as a quantitative value and visualized through the monitor 120 (step 218).

Although not shown in FIG. 2, the attack priority calculation unit 117 calculates the degree of threat to the entire target of the threat evaluation, and determines the attack priority for each target according to the calculated degree of threat of each target Ranking can be calculated, so that arbitrary armed assets are responded to, or the attack priority calculation result can be visually displayed through the monitor 120 so that the operator can recognize the attack priority.

In the embodiment of the present invention, when there are N targets, the threat level is sequentially calculated by one target. However, the present invention is not necessarily limited to this, , Computing the first and third proximities parallel to the overall target, computing the second and fourth proximities in parallel for the entire target, and calculating the fifth proximity for the entire target in parallel And it is also possible to design the threat to be calculated in parallel with respect to the entire target.
