Abstract

In order to track the moving target precisely on the airport surface, the Variable Structure Interacting Multiple Model Algorithm (VS-IMM) is applied to realize the Surface Movement Radar (SMR) tracking of target. 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 VS-IMM algorithm is applied to the airport surface movement target tracking. Finally, VS-IMM is compared with IMM. Simulation results show that VS-IMM algorithm is more reliable than IMM algorithm on tracking of moving target on airport surface
