Aerial Target Threat Evaluation Method Based on Information Entropy and Subjective Preference Synthesis

Aimed at the problem existed in aerial target threat evaluation,a kind of aerial targets threat evaluation method based on interval-number combined information entropy with subjective preference was proposed.The weights of evaluation indexes were calculated by use of considering both objective situation and the decision makers' preference.The correlation coefficients of the positive ideal target were introduced and the assessment model was established.Finally,the practical applicability and the effectiveness of this method were verified with the aid of the simulation example.
