Considering that the near space hypersonic target has the moving characteristics of rapid flight speed, high maneuverability, and periodic sliding jump, we proposed a near space target tracking algorithm based on interaction of different Sine models. First, in view of the periodic sliding jump trajectory of the near space target, a sine model based on low angular rate is adopted to improve the accuracy of near space target tracking. Then, in view of the unknown parameters and moving characteristics of the sliding trajectory, Sine models with different angular rates are interacted, to further improve the matching degree of the model with periodic sliding jump trajectory of near space target. The simulation experiments show that, compared with the existing near space target tracking algorithms, this algorithm has higher tracking precision.
