Non-cooperative maneuvering target tracking based on smoothers

This paper presents the problem of real-time tracking measurements of maneuvering target. discusses the optimal kalman smoother, introduced smooths methods, and compared the methods of Kalman filter and Kalman smoother, Unscented Kalman filter and Unscented Kalman smoother, Interacting Multiple Model Smoother(IMMF) based on the Multiple Model idea. Meanwhile, For the problem of nonliner based on the radar measurements and the target charicterristic, designed the classed scenes to teste the new methods, experiment results show the effectiveness.
