  • Radar tracking for hypersonic glide vehicle based on aerodynamic model

    • 摘要:

      In order to achieve hit-to-kill in terms of intercepting the hypersonic glide vehicle, the first task is to accurately track the flight state and predict the trajectory. In this paper, a radar tracking approach for hypersonic glide vehicles is proposed based on a novel aerodynamic model. The extended motion equations are derived on basis of the established aerodynamic acceleration, and the measurement equations of radar are given. In view of the nonlinearities, the extended and unscented Kalman filters are adopted to estimate the extended state, respectively. To examine the proposed method, two types of standard trajectories are designed and then tracked. Simulation results indicate that it can precisely track the hypersonic glide vehicle, which provides a guarantee of the following trajectory prediction.
