针对现有空战态势显示结果不直观、不便于飞行员使用的问题, 基于三维威力场, 提出一种基于九宫格的态势显示与辅助决策方法。该方法使用威力势公式计算态势平面上的威力势分布, 使用改进下采样法对态势平面求均值, 使用TOPSIS法与可拓K近邻算法计算相对威胁等级, 并给出建议飞行方向。仿真算例验证了方法的有效性。研究结果表明使用九宫格进行态势显示与辅助决策对作战决策能够满足作战需要。

In view of the problem that the display result of air combat situation is not intuitional and not convenient for use, a method for situation display and assistant decision-making based on Sudoku and the three-dimensional combat power field is given.This method uses combat power formula to calculate the power distribution on the situation plane, the improved down-sampling to calculate the average of the situation plane, and the TOPSIS and K nearest neighbor algorithm to calculate the relative threat level.Then, the recommended flight direction is given.Simulation result proved the validity of the method.The result of research shows that using Sudoku is helpful for situation display and assistant decision-making.
