Cooperative tracking for Hypersonic Technology Vehicles based on EIF-IMM

This technical note considers the cooperative tracking problems for Hypersonic Technology Vehicles. Combined with the characteristics of the Hyersonic Vehicles' trajectories, this note builts a skip glide maneuvering model of which the accelerator is near periodic and the cycle is estimated from the historical data in real time. Two structures of cooperative tracking, centralized cooperative tracking and distributed consensus tracking, are proposed in this paper. A method of EIF-IMM is presented in the centralized cooperative tracking to improve the tracking accuracy. In order to solve the consensus problem in distributed tracking, a consensus EIF-IMM algorithm is put forward. Simulation results demonstrate that centralized cooperative tracking based on EIF-IMM and consensus EIF-IMM algorithm in distributed consensus tracking can improve the accuracy of tracking hypersonic vehicles compared to the tracking results by single agent.
