Air combat threat assessment refers to how to judge and estimate the possibility of an enemy target to hit our success and may cause the extent of the damage. Air combat threat assessment is to improve the correctness of the decision, and to effectively improve their survival probability. It has important practical significance to research threat evaluation on the battlefield combat application.Traditional air combat threat evaluation method is to use some target-specific parameters and the modern analytical methods to evaluate the threat of the targets and the sort for all targets. If the evaluation results of many targets are similar or the same, decision-maker cannot make directly the attack sequence according to the evaluation results. In particular, lead to decision-makers is no intuitive understanding and master for the development trend of air combat.Thus, the model of air combat threat visual evaluation respectively under the situations of the perfect information, the imperfect information and based on intuitionistic fuzzy sets are established according to visual method in this paper. The sorting results of the air combat threat evaluation through the method are not only correct and reasonable, but the decision-makers can directly get the current threat situation and intuitively analyses the threat of development trend based on the results of evaluation. The main research contents are as follows:The objective weight of the target attribute determined by the cross entropy method, and the comprehensive weight determined by the combining the subjective weight determined by the group analytic hierarchy process method. At the same time, using angle bisector to drawn radar figure solved the defects of traditional methods. And the mathematical model of evaluating based on improved the radar chart is established.In the case of collect information is perfect, a visual evaluation method of air combat threat based on improved the improved radar chart is proposed. The model is established by the selected attributes factors of air combat threat evaluation. And the results of simulation and analysis show that the method is scientific.In view of the collection of air combat information is defect, a visual evaluation method of air combat threat based on the improved radar chart under incomplete information is proposed. By collecting the air combat information of the latest and continuous time, and the interval decision matrix is constructed by the interval value theory. And the model of air combat threat visual evaluation based on improved the radar chart under incomplete information is established. The simulation results show that the method can not only solve the problem of missing data, but intuitively see the development trend of target threat.According to the development trend of modern air combat, a visual evaluation method of air combat threat based on improved the radar chart of intuitionistic fuzzy sets aim at the uncertain information in the air combat. It employed the intuitionistic fuzzy sets to determine the decision matrix, and the comprehensive weight determined by the intuitionistic fuzzy entropy algorithm and the group analytic hierarchy process method. And the model of air combat threat visual evaluation based on the improved radar chart of intuitionistic fuzzy sets is established, and the radar graph draw by the radar map based on intuitionistic fuzzy sets, and the simulation results demonstrate that the method is feasible.
