Abstract:

To track the moving targets precisely on the airport surface, the interacting multiple model (IMM) algorithm is applied to realize the surface movement radar (SMR) tracking of targets. Firstly, according to the actual movement of aircraft, the paper establishes a constant acceleration motion model, constant turn motion model and constant velocity motion model. Then, the UKF-IMM filter algorithm (IMM based on the unscented Kalman filter) is applied to the airport surface movement target tracking. Finally, UKF-IMM is compared with the IMM algorithm based on the extended Kalmam filter (EKF) and the single model tracking algorithm based on current statistical model. Simulation results show that UKF-IMM algorithm is more reliable than the other two algorithms on tracking of moving targets on airport surface.
