Abstract:

The significance for integrated usage of prior dynamic character, system structure and measurement information is suggested. Then, three key steps for the tracking filter are reviewed, i.e. the maneuvering modeling, the nonlinear filter algorithm and the measurement error detection and calibration. Furthermore, designing method for real time tracking system is discussed according to the deficiencies of those existing systems. The method is aim to established an efficiently integrate data processing flow, and achieve an effective fusion of all available system information by hydride fusion strategies. Many actual tracking filter systems can draw lessons from here. Finally, the possible future researches for real time trajectory target tracking are also investigated according to the demand pull space applications.
