To improve the tracking accuracy of hypersonic jumping gliding target in near space

a new type of maneuvering tracking model with second order time correlation is put forward based on the characteristic analysis of near space hypersonic vehicle target motion

the key of the model is to model target's acceleration as a zero mean random process with attenuation oscillation autocorrelation

and the state equation of tracking the near space hypersonic jumping gliding target is built; in order to further analyze the adaptability of the model

the system dynamic error steady state value of the model is deduced by combining the Kalman filtering algorithm

and the adaptability of the model is discussed from the point of the model parameters; then the relationship between the two parameters in the model is analyzed to improve the rationality of the model parameters

and the approximate reference interval of the parameters are given. The theoretical analysis shows that the model has the unity of periodicity and attenuation

which is mainly expressed as periodic in a short time

and mainly expressed as exponential decay in a long time

these feature improves the rationality of the description of the motion of near space hypersonic jumping gliding target

in addition

the model has a low system dynamic error steady state value when the theoretical value of the model parameters in tracking the near space hypersonic jumping gliding target are obtained. Simulation results show that the model has a higher tracking accuracy when compared with the existing single noise maneuvering model of the near space hypersonic target; and the rationality of the method of parameterization is explained by comparing the simulation results under different parameters.
