用guide编的matlab界面,可以点击图像任意位置截取一小块(Guide prepared by the matlab interface, you can click the image anywhere on the interception of a small piece of)

you can see how the ball is tracking on the short movie

matlab的gscale函数功能是将强度图像等映射到别的值范围(Function of matlab gscale intensity image is mapped to a different range of values, etc.)

啁啾脉冲对传输特性的影响，用MATLAB实现可视化(chirp pulse)

用功率谱的方法求系统频率特性，采用MATLAB仿真，输入信号为Chirp信号和Multitone信号。(Using power spectrum method for frequency characteristics of the system using MATLAB simulation, the input signal for the Chirp signal and Multitone signal.)

使用PAST算法进行子空间分析，MUSIC算法进行频率估计，实现了对信号的频率跟踪(Using the PAST subspace analysis algorithm, MUSIC frequency estimation algorithm to achieve the signal frequency tracking)
