Threat assessment method based on three-way decision

Abstract

The invention provides a threat assessment method based on a three-way decision. The threat assessment method comprises the steps: determining target feature information detected by a radar, obtaininga target information matrix, obtaining a target assessment function in the three-way decision according to the target information, employing a simulated annealing algorithm to select the optimal threshold of the three-way decision, and carrying out three-way decision on the threat degree according to the optimal threshold. According to the threat assessment invention, three decision theories areintroduced into target threat assessment; targets are successfully divided into high threats; and in the three domains, namely the low threat domain, the low threat domain and the boundary domain, a decision maker can make a targeted decision on the target according to the divided three domains, and compared with a traditional method which only sorts the threat degrees of the target, the decisionmaker makes a command and decision, and the decision maker can make a command and judgment more conveniently and rapidly through system classification of the target. Compared with the traditional two-way decision, the introduction of the boundary domain in the three-way decision also reduces the possibility of making an error decision only for the high threat domain and the low threat domain to acertain extent.

Description

technical field [0001] The invention relates to the field of threat assessment, in particular to a threat assessment method. Background technique [0002] Threat assessment is to evaluate the combat capability and threat of the opponent's forces based on the current battlefield situation. The threat assessment process involves many uncertain factors: the uncertainty of the target type, the uncertainty of the attack method, the environment of the battlefield combat area, and the uncertainty of the weather. Therefore, threat assessment is an online tactical decision-making problem under the conditions of incomplete information, uncertain information, and vague information. In air defense warfare, threat assessment is an important prerequisite for our firepower strike deployment and command decision-making. The more accurate the threat assessment of the target, the more targeted the subsequent decision-making command will be, and the better the combat effect will be. Therefor...

Problems solved by technology

[0004] In order to overcome the deficiencies of the prior art, the present invention provides a threat assessment method based on three-way decision-making, aiming at solving the problem of uncertain target information in threat assessment

The invention establishes a three-way decision-making model, which can solve the problem of information uncertainty in threat assessment, and divides the target into three domains according to the classification threshold of the three-way decision-making: positive domain (high threat), negative domain (low threat), boundary area
