The invention relates to a label particle multi-extension target tracking method based on an ellipse RHM, and the method comprises the steps: building an augmentation space, and initializing a label particle set; carrying out measurement division, supplementing new label particles according to a measurement division unit and the measurement in the measurement division unit, and combining the new label particles with a survival label particle set; predicting and updating the label particle set generated by merging according to a prediction equation and a likelihood equation; performing label processing on the updated label particle set to obtain multiple extended target number estimation, and associating multiple extended target state estimation with a track; and after the label particle subset after label processing is resampled, carrying out target mass center state extension and shape estimation at the next moment. The invention is high in operation speed and high in tracking precision, the mass center state and shape of the multiple extended targets can be accurately estimated, the target track can be obtained, and different targets can be distinguished.
