Extended Information Filter for Tracking High-speed Target with Maneuver

Tracking High-speed targets accurately is increasing crucial for subsequent interception process. This paper proposes a novel extended information filter aided by dynamic model extension to realize accurate tracking. In this scheme, the target acceleration is estimated and compensated to accommodate for the unknown model perturbation. Additionally, the measurement equation introducing radar-based radial velocity is derived. Simulation results demonstrate that the effectiveness of the proposed method. Moreover, the proposed method has advantage over traditional method in filer convergence and stability.
