Maneuvering Target Tracking with A-Prior Point's Constrained Information Based on Trajectory Function of Time

In this paper, we consider the maneuvering target tracking problem based on the framework of the trajectory function of time (T-FoT). We aim at the specific class of the target that its trajectory is smooth and we can know some important constrained points that the target's trajectory will pass in advance during the target motives. Reasonably using these a-prior points's constrained information (like the starting point, the destination and the maneuvering point) in the fitting process, we can improve the estimated accuracy. The maneuvering example has been used for demonstrating the advantage of our proposed approach in comparison with traditional filters.
