In order to make the midcourse recognition plan of ballistic missile more close to the actual combat sceneit is necessary to evaluate and analyze the plan.According to the actual combat scene and the existing detection capability levelan evaluation index system of the midcourse recognition plan for anti-missile early-warning is established,and the meaning of different indexes is explained.After thatexperts are invited to score the indexes of the plan to be evaluatedand the correlation degree between the indexes of the plan to be evaluated is calculated by using the method of matter-element theory.On this basisthe matter-element theory and the evidence theory are organically combined by using the normalized processing methodand the level to which the plan belongs is determined by using the formula of synthesis rules in the evidence theory.Experiments have proved that this method can effectively reduce the difficulty of obtaining mass functions in the evidence theory and their high subjectivitywhich makes the synthetic result more objective and accurateand the evaluation conclusion more convincing.
