Aiming at the tracking problem of small infrared target doing non-linear action,a tracking method is designed based on IMM.Firstly,multi-motion-model is introduced;then the state estimate of each model is calculated by using unscented Kalman filter;finally the total state estimate value is got through certain probability.By means of mathematic simulation and physical experiment,the eliminating yawp and forecast function is tested,and the results shows that this system is effective to track small infrared target in complex context.
