Abstract: Air combat target threat assessment is the basis of target allocation and firepower allocation. When the weight of target threat assessment indexes is determined, the correlation between the assessment indexes is not considered. And the single grey relation analysis (GRA) method and the single technique for order preferenceby similarity to ideal solution (TOPSIS) cannot accurately reflect the threat degree of target, in which the different attitudes of a pilot towards the loss and gain in the decision-making are not considered. Based on GRA and TOPSIS methods, a prospect theory and GRA-TOPSIS target threat assessment model is proposed. A concept of grey correlation depth is presented, and the weight of assessment index is determined by combining maximum entropy. The variable weight gray correlation threshold method is used to adjust the weights of assessment indexes to avoid the index-relevance effect. Finally, GRA method is used to analyze the curve shape similarity of index series, and TOPSIS method is used to analyze the position similarity. Baesd on the prospect theory, and the attitudes of pilots towards gains and losses, the threat assessment results can reflect the traits of pilots. Simulated results show the effectiveness and rationality of the proposed methods. Key
