基于DTW距离的空天防御目标威胁评估OA

Aerospace defense operations are strategic,dynamic and uncertain,which poses great challenges to threat assessment.Aiming at the problem that traditional threat assessment methods are difficult to deal with the dynamic and time-unaligned characteristics of decision-making information,this paper optimally integrates the subjective weight obtained by the AHP method and the objective weight obtained by the entropy weight method.The TOPSIS algorithm is improved from the selection of ideal solutions and the calculation of relative closeness through time weighting,time series dominance,and dynamic time warping(DTW)distance,so as to achieve threat assessment for aerospace defense targets.The example shows that the proposed method can solve the problem of dynamic and time-unaligned decision-making information and effectively implement the threat assessment of aerospace defense targets.
