这是非常好的滤波算法，一般在做雷达或导航时，求速度或位置时用，比卡尔曼滤波好用-This is a very good filtering algorithm, usually in the radar or navigation, seeking speed or position when used, better than Kalman filtering

基于卡尔曼滤波的目标跟踪和轨迹预测，广泛应用于雷达信号，MATLAB实现-Kalman filter based target tracking and trajectory prediction, widely used in radar signal, MATLAB realization

本文对卡尔曼滤波的原理进行了研究，然后将其应用到雷达跟踪预测领域。-In this paper, the principle of Kalman filter is studied, and then applied to radar tracking and prediction.
