It is important to develop a robust and fast tracking algorithm for modern tracking system because the target moves more and more fast. Therefore, a novel algorithm named the iterative unbiased converted measurement Kalman filter (IUCMKF) is proposed based on the analysis and comparison of conventional target tracking methods. The new algorithm is developed from unbiased converted measurement Kalman filter, but it can obtain more accurate state and covariance estimation. Compared with the existi
