IMM algorithm for a 3D high maneuvering target tracking

摘要

A major challenge posed by target tracking problems is the target flying at high speeds and performing "high-g" turns in the 3D space. In this situation, horizontally or decoupled models may lead to an unacceptable accuracy. To address this problem an IMM algorithm that includes a 3D constant velocity model (CV), a 3D "current" statistic model (CSM), and 3D constant speed coordinated turn model (3DCSCT)with the kinematic constant for constant speed targets is proposed. The tracking performance of the proposed IMM algorithm is compared with that of an IMM algorithm utilizing CV, 3DCSCT, and constant acceleration model (CA) or singer model. Simulation results that demonstrate the algorithm is feasible and practical for a 3D high maneuvering target tracking.
