Abstract: To address the near space hypersonic jump gliding target tracking problem, an Adaptive Non-zero Mean Sine Wave (ANM-SW) model is proposed on the basis of modeling acceleration as a random process of Sine Wave (SW) autocorrelation. The core of the model is to compensate the mean SW and construct the ANM-SW model; in this process, the state equation of the model is derived. To further analyze the role of mean compensation with this model, the physical nature of adaptive non-zero mean value model is discussed from the perspective of time domain and frequency domain. Furthermore, the system dynamic errors of SW and ANM-SW models status update are deduced taking Kalman filter as the filtering algorithm. In this way, the superiority of ANM-SW model in maneuver adaptation is verified. Finally, the simulation experiments show that compared with SW model, ANM-SW model has certain advantages in tracking accuracy and maneuverability.
