Abstract: To solve the problem that the single Sine model algorithm cannot match the near space hypersonic slippage leap trajectory accurately, and the tracking effect of the existing interactive multiple model (IMM) algorithm is not ideal, an adaptive interactive multiple Sine model (Sine-AIMM) tracking algorithm based on multiple Bayesian criteria is proposed. In the algorithm, multiple Sine models are used to match the slippage leap trajectory, and multiple Bayesian criteria are used to adjust the weight of each model and the transition probability matrix of the model online. The simulation results show that the proposed Sine-AIMM algorithm can effectively track the near space hypersonic slippage leap maneuvering target, and the tracking performance is better than that of the single Sine model algorithm and the IMM algorithm.
