Abstract: In order to improve tracking precision of strongly maneuvering targets and realize better target tracking, an improved method is put forward based on current statistic model and Kalman filtering algorithm. Current statistic model is analyzed, and then the advantages and shortcomings are separately concluded while targets are in weakly and strongly maneuvering state. The measuring of maneuvering status is conducted to judge the maneuvering standard, a lessening factor is introduced in Kalman filter, which weakens the effects of former data and reflects current status, and each parameter is identified on line, and adjusted adaptively in accordance with maneuvering level. The simulation indicates the improved method maintains the usual properties, and gains better tracking precision in strongly maneuvering state.
