Abstract： This paper studies the accurate tracking problem under the condition of unknown or changing turning rate, an adaptive coordinated turning tracking algorithm based on UKF is proposed. The algorithm makes full use of the dimensionality extension technology and the adaptive fading factor technology, continuously estimates the turning rate in real time and adjusts the process noise and its corresponding gain based on the fading factor. At the same time, adaptively adjusts the sampling range of the unscented Kalman filter algorithm to make the sampling points closer to the real state of the target. Simulation results show that the algorithm achieves good tracking performance when the turning rate changes, and effectively improves the accuracy and stability of tracking maneuvering target.
