The invention belongs to the field of maneuvering object tracking, and discloses a weight-modifying variable structure multi-model maneuvering object tracking method. The method comprises the steps: initializing a radar observation value, and obtaining an initial state vector and an initial covariance matrix; selecting an initial angular velocity, and determining a state transition matrix of a motion model; carrying out multi-model filtering, obtaining a state estimation vector and an estimation covariance matrix, and obtaining multi-model weights; employing a variable structure and the idea of the graph theory, and carrying out the adjustment of the angular velocity (the multi-model structure) through the multi-model weights till the tracking is completed. The method is good in tracking performance, is small in calculation amount, and can be used for the tracking of a high-speed strong maneuvering target.
