Huber-Based Robust Tracking Method of Hypersonic Cruise Vehicle
摘要
In order to solve the tracking problem of hypersonic cruise vehicle (HCV) during high-speed flight, a robust tracking method (CHF) for hypersonic cruise vehicle is proposed. Firstly, the hypersonic cruise vehicle tracking model is established, including a vehicle motion model, a tracking model, a ground-based radar measurement model and a flicker noise model. On this basis, for the nonlinear problem of the system, the tracking method based on deterministic sampling is adopted. Aiming at the noise non-Gaussian problem caused by high-speed flight, a robust tracking method based on Huber-based hypersonic cruise vehicle is proposed. Finally, comparative simulations under various conditions are carried out to verify the effectiveness of the robust tracking method based on Huber. The simulation analysis of the tracking and positioning accuracy of hypersonic cruise aircraft was completed from the aspects of angle measurement accuracy and frame rate measurement. The comparison of CKF and CHF algorithms under different intensity flashes shows the superiority of CHF algorithm in hypersonic cruise vehicle tracking, and higher estimation accuracy and system robustness can be obtained.
