用Kalman滤波方法估计目标航迹的Matlab源程序(Kalman filtering method estimates the target track Matlab source)

实现低通，高通，带通的不同类型滤波器，并用几个基本的函数进行了验证(Low pass, high pass, the different types of band-pass filter, and a few basic functions were verified)

说明：  LMS自适应滤波器是使滤波器的输出信号与期望响应之间的误差的均方值为最小，因此称为最小均方（LMS）自适应滤波器。(LMS adaptive filter is to minimize the mean square value of the error between the output signal of the filter and the expected response, so it is called LMS adaptive filter.)
