摘　　要：针对已有评估方法存在的不足,提出一种改进的灰色关联空袭目标威胁评估方法。构建了空袭目标威胁评估指标体系,借助组合权重理论,将主客观权重进行差异性赋权,有效提高评价指标的可靠性。在此基础上,利用灰色关联法建立了空袭目标威胁评估模型。最后通过实例分析验证,该方法评估结果准确,对指挥员科学决策具有一定的参考价值。Air target threat evaluation is an important component of air defense command decision-making.It ranks the threat levels of all air targets,distinguishes the priority of the targets,and provides a basis for firepower allocation.At present,in the research on threat assessment of air raid targets,the main approach is to obtain target attribute parameters through sensors.However,due to the complexity of the battlefield environment,the information obtained by sensors often has a certain degree of randomness and uncertainty,which can easily cause certain deviations in the evaluation results.Therefore,it is necessary to appropriately combine the commander’s combat experience in the evaluation process.In response to the shortcomings of existing evaluation methods,a threat assessment index system for air raid targets has been constructed.The threat assessment factors are generally the target state information obtained by sensors and the target attribute information obtained by information fusion.There are many factors that affect the threat assessment of air raid targets,including target type,target speed,target distance,flight altitude,interference ability,maneuvering status,target acceleration,number of targets,route shortcuts,target azimuth,target RCS,air raid style,remaining time,and so on.These attributes are not independent of each other and usually have a certain connection.Through analysis,we can divide the evaluation factors into two categories:Combat capability and attack intent.Combat capability is determined by the attributes of the target itself,while attack intent is mainly determined by the target’s flight actions.From this,a system of threat assessment indicators based on target type,target speed,route shortcut,flight altitude,maneuvering status,and arrival time can be obtained.With the help of combination weight theory,the objective information obtained from sensors is weighted differently from the subjective experience of the commander,greatly improving the accuracy of the evaluation process.The com
