本程序主要针对卡尔曼滤波程序进行仿真，主要为目标运动的轨迹估计，相对于之前的程序这次在观测信号中含有距离、速度、加速度信息！
程序正确完整，适合了解卡尔曼的同事学习交流！(This program focuses on kalman filter simulation, mainly for the target motion trajectory estimation, relative to the program of the observation signals contain before distance, velocity and acceleration information!
The program is correct and complete, it is suitable for the colleague of kalman to learn to communicate!)
