New Algorithm for Hypersonic Target Tracking

In view of the problem that it is difficult to use a classic tracking model for describing accurately accurately the acceleration dynamic characteristics of maneuvering targets while the flight speed of hypersonic targets being fast and their maneuvering capacity strong, this paper puts forward a sort of improved interacting multiple model tracking algorithm. In this algorithm, the concept of reference acceleration is brought in, describing more accurately the moving characteristics of targets, and combining a priori information with dynamic information of target maneuvering. The simulation results demonstrate that the proposed method is of fast convergence, low RMSE, and high tracking accuracy when tracking hypersonic targets, and of stronger adaptability, compared to Singer-IMM algorithm.
