Summary: | The invention discloses a maneuvering detection method based on model probability matching, and the method comprises the steps: analyzing different characteristic parameters when a hypersonic reentry vehicle has a maneuvering sudden change, constructing a maneuvering model description matrix, and determining a maneuvering model; defining an influence factor, and designing a model matching degree function; threshold values are set for feature parameters of different maneuvering models, and matching vectors of the current system and each preset model are calculated by integrating actual feature parameters of the current system; substituting the prior influence factor and the calculated matching vector into a model matching degree function, and calculating a model matching probability; calculating a model probability correction sequence according to the probability that different maneuvering models preset at the current moment conform to the real state, and finally correcting a model probability vector; and judg |
