Abstract In order to achieve highprecision tracking of highspeed glide vehicle, a tracking algorithm for hypersonic jump-gliding maneuvering targets in the near space is proposed. Its core is based on the SW (Sine Wave) model, which combines the digraph switching principle with the interactive multi-model algorithm to achieve the adaptation of the model set. In order to cover the change of the periodic maneuvering angular velocity, the cubature Kalman filtering method is used to design the filter. The simulation experiment is compared with SW single model and SW interactive multi-model to verify the superiority of the proposed algorithm when tracking the hypersonic jump-gliding maneuvering target in near space and the effectiveness of model set switching.
