Abstract: A two-layer Interactive Multiple Model（IMM） tracking algorithm is put forward for high speed and high maneuvering target, which includes complex maneuvering modes, especially turn maneuvering. The inner layer is composed of modified current statistical model. Turn angular velocity and angular acceleration can be attained by filtering the heading angle of target. The outer layer is composed by constant model and curvilinear model. Cross-track acceleration and turn angular velocity of curvilinear model parameter could be adjusted adaptively from inner layer model. The outer layer models are filtered by IMM. The simulations show that the algorithm has better tracking precision for high speed and high maneuvering target. The algorithm is easily implemented, and the algorithm has some practical application value.
