Multi-parameter fusion missile state evaluation method based on improved evidence theory

The invention relates to a multi-parameter fusion missile state evaluation method based on an improved evidence theory, comprising the following steps of 1 establishing a missile state evaluation model; 2 carrying out state evaluation on each performance characteristic parameter of a certain missile, and obtaining a state membership degree of each performance characteristic parameter with normal test result belonging to a good, good, usable and quasi-fault state grade; 3 determining that weights of each performance characteristic paramete; 4 performing fusion treatment on that states of each performance characteristic parameter to obtain the state membership degree of a certain missile belonging to good, good, usable and pseudo-fault state grades; 5 making the corresponding state level decision for a certain missile, and determining the final state level of a certain missile. The evaluation result obtained by the invention is reasonable and effective, the current state of the missile can be well determined, t
