研究物体跟踪，利用kalman方法，编写matlab程序。

用于卡尔曼滤波器自由落体运动，完成对目标位置的观测，跟踪-Used for kalman filter free fall, complete the observations of the target location tracking

假设一物体围绕一圆周运动，角加速度是白噪声，观测噪声也是零均值的白噪声。编程使用卡尔曼滤波器实现运动物体的跟踪。-Suppose an object around a circular motion, the angular acceleration is white noise, measurement noise is zero mean white noise. Programming using a Kalman filter to achieve tracking moving obj

卡尔曼滤波对移动目标的定位与跟踪，效果明显，可以实时的对移动目标进行定位跟踪-Kalman filter positioning and tracking moving targets, the effect is obvious, can real-time location and tracking of moving targets

用卡尔曼滤波器实现PLL,能够作为同步中的跟踪部分-realize PLL by kalman filter
