A method of target tracking based on spatial trace matching principle

A new method called track smooth filter(TSF), which improves the tracking quality of target track, is presented for the situation that the measuring data rate is low, the system feature and the target movement is complicated. Based on the spatial trace matching principle that the track made by the target motion is continual and smooth, simple and robust estimation models can be constructed by the regression analysis for the target kinematics process with unknown behavior. The state estimations of the target are obtained by the smooth filter so as to establish the target track. In applications on the experimental data, it is shown that the adaptability and the stability of the track filter are well.
