Description

Target damage assessment apparatus, method, computer-readable recording medium and computer program

The present invention relates to a target damage assessment apparatus, method, computer-readable recording medium and computer program.

Computer-based M&S (Modeling & Simulation) is being used in a variety of ways in the defense field, such as weapon system development process, military policy analysis, future battlefield environment prediction, and scientific training.

At this time, the M&S used in the defense field is called the national defense M&S system, and the defense M&S system is a system between a weapon system (eg, munition, target) that properly reflects the properties of a weapon system used on the battlefield. It requires a damage assessment that defines how to deal with conflicts when they occur.

As a method for such damage evaluation, a method using the weapon effect index was used. Here, the weapon effect index quantifies the degree of damage that a specific weapon inflicts on a specific function of a specific target, and the killing probability, which is one of the weapon effectiveness indices, indicates the degree of damage (damage potential) that a specific weapon inflicts on a specific function of a specific target. is shown as

Because the existing killing probability calculation process calculates the delivery accuracy, which is the probability that the bullet will hit the target, only considering the circular error probability (CEP) at the center of the target, environmental factors that occur during actual engagement, e.g. For example, consideration of conditions such as wind strength, direction, and temperature and shielding by obstacles was limited.

Therefore, when using the weapon effectiveness index method in the defense M&S system, users or experts had to use a method such as adjusting the index by experience and consensus in order to consider the environmental conditions in which the engagement takes place.

However, even if the user or experts consider the environmental conditions in a way such as adjusting the index by experience and consensus, it was not possible to accurately reflect the environmental conditions that occur during actual engagement. There was a problem in that the accuracy of the desired level of damage (probability) data was lowered.

Including instructions for causing the processor to perform a method including calculating the damage of the target due to the simulated bullet based on the position of the simulated bullet impacted on the reference damage evaluation plane
computer readable recording medium. As a computer program stored in a computer-readable recording medium,
