Abstract:

The identification of staging and burnout for the boost phase object play an important role for the tracking system to determine the target’s flight mode transition and deploy the subsequent tracking. First, the dual-stage boost phase kinematic model and the coast phase kinematic model which associate with the staging and burnout are derived. Second, the interacting multiple model framework is introduced to solve the target track problem with the structural uncertainty, and the unscented Kalman filter is used to figure out the nonlinear estimation problem. Finally, the simulation in the condition of space-based observations is conducted, which is shown that the staging and burnout can be efficiently identified via the abnormal change of the mode probability and the overall covariance.
