Visualization threat assessment for air combat based on interval-radar chart

Considering that the traditional air combat threat evaluating methods are difficult to intuitively reflect the situation and development trend of the target threat, a method of visualization threat assessment for air combat based on interval-radar chart is proposed. Firstly, the normalized decision matrix of target attribute is determined by the interval number and anti-trigonometric function. Then, the weight of target attribute is calculated by the methods of interval cross entropy and the group decision analytic hierarchy process, and the target threat is graded. Finally, the mathematical model of the visualization threat assessment for air combat is established with the improved radar chart method. The simulation results show that the method intuitively analyzes the situation and development trend of each target threat under the premise of the correct assessment results.
