最近和一位研友交流时谈到Matlab时频分析,了解到Matlab并不提供直接的绘制时间-频率分布图的命令,而是以时间-尺度图代之。不过很多时候我们要用到时间-频率图来分析信号,这两天集中搜集了相关的资料,其中在 MathWorks.com 的 Fileexchange 中心找到一个不错的Matlab时频分析工具,使用 Matlab GUI 界面开发,内核用C编写,感觉使用方便,分析和作图速度快,而且有多种图形表达方式选择。-Friends of the recent research and a

1.本程序拟已知驻波比系数ρ,波节点的距离l_m_i_n,和频率f的情况下,求解归一化阻抗Z~,
所以在本程序运行时,要首先输入正确的驻波比系数ρ,波节点的距离l_m_i_n,和频率f;
2.本程序由于视野有限,课本后面的那个圆图并未全部显示出来,只是显示了本程序有用的部分
3.编制本程序的小组成员为微波技术实验分组,倪庆等;
4.由于时间原因,未能打成exe可执行文件包;
5.由于圆图信息量大,所以运行后要把窗口最大化才能正常显示;
6.红色的圆点即为阻抗
