An IMM-based adaptive-update-rate target tracking algorithm for phased-array radar

This paper addresses the problem of adaptive-update-rate target tracking in the phased-array radar. A novel IMM- based adaptive-update-rate method is proposed. The update interval is proportional to the inverse square root of the position residual. A controllable parameter is introduced in the formulation of calculating the update interval which can be used to balance the tracking precision and the system load. Simulation results demonstrate the effectiveness of the proposed algorithm.
