Abstract

The invention discloses a target tracking method based on interactive multiple models. The target tracking method comprises the following five steps of 1, according to the target dynamic condition, setting five groups of Singer model parameters, and building five Singer models; 2, performing interactive multiple model nonlinear filtering on the five Singer models, and evaluating the movement speed, acceleration and position information of a target; 3, by using the movement speed and acceleration of the target, calculating the turning angle rate of the target; 4, comparing the turning angle rate of the target and a set threshold value, and judging whether the turning movement occurs or not; when the turning movement does not occur, using the position information obtained in step 2 as a target tracking result; 5, when the turning movement occurs, selecting turning angle rates of three adjacent moments to build three turning models, and performing the interactive multiple model nonlinear filtering, so as to obtain the target position as the target tracking result. The target tracking method has the advantages that the implementation is easy, the target tracking accuracy is improved, and the reliability and accuracy of the target tracking are guaranteed.

Description

technical field [0001] The invention relates to an interactive multi-model based target tracking method, which belongs to the field of target tracking. Background technique [0002] In the field of target tracking, the interactive multi-model (IMM) algorithm has become a widely used target tracking algorithm due to its excellent performance. Dynamic tracking results. In the interactive multi-model algorithm, the accuracy of the model has a great influence on the tracking result. [0003] Turning motion is a common form of maneuvering in target tracking. Scholars at home and abroad often use turning models to test maneuvering target tracking algorithms. The turning model is mainly modeled by the turning angular rate, and the accuracy of the turning angular rate of the target motion directly affects the modeling accuracy of the turning model. Therefore, to effectively use the turning model to track the target's turning maneuver, it is necessary to be able to estimate the tu...
