快速机动目标跟踪算法研究

根据空间目标作匀速转向运动的特点，提出了一种基于航向变化的目标加速度实时估计方法，在此基础上采用采样卡尔曼滤波器对该机动目标进行跟踪。仿真结果表明，这种新的加速度估计方法不仅能检测出目标机动开始和终止时刻，而且还能估计出快速机动目标的加速度大小，与扩展卡尔曼滤波器相比，采样卡尔曼滤波器具有更好的跟踪精度。

Study of Fast Maneuvering Target Tracking Algorithm

According to the characteristic of uniformly bearing target in space,this paper proposes a new real time acceleration estimation method based on the target heading change,adopts the unscented Kalman filter to track the fast maneuvering target.Simulation results show that this new acceleration estimation method not only can detect the start and end time of target maneuver,but also can estimate the acceleration of maneuvering target.Compared with the extended Kalman filter,the unscented Kalman filter has better tracking accuray.
