摘　　要：针对弹道导弹的变轨问题,给出了基于模糊隶属度的多目标关联算法,在此基础上建立了预测弹道的单目标变轨识别以及变轨时间确定方法,掌握了导弹目标变轨过程中轨道变化的规律,为平时导弹机动能力搜集以及战时导弹预警和拦截提供了支持,给出了相应的仿真算例.结果表明,该方法可以较好地判断目标何时进行了机动变轨,具有一定的实用价值.In order to deal with missile maneuver identification, a multi-objective connection algorithm was given based on fuzzy membership degree. The missile maneuver recognition algorithm was established, and the maneuver time was also given by this algorithm. The law of missile maneuver was known. The law offers reference for collecting the cases of missile maneuver ability at peacetime, missile warning and interception at wartime. The simulation example was presented. The result shows that the time of missile maneuver can be identified by this method, and the method is feasible.
