对高速运动目标采用基于kalman filter进行预测。基于matlab的实现，来进行运动目标的轨迹预测。有卡尔曼算法，扩展卡尔曼滤波，数据拟合方法。(The high-speed moving target is predicted based on Kalman filter. Based on the realization of MATLAB, the trajectory prediction of moving objects is carried out. There are Kalman algorithm, extended Kalman filter, data fitting methods.)
