1．步进频率信号的压缩实验。编写Matlab程序，得到类似如下两图的结果。步进频率信号参数：（1）载频f0 = 5.321GHz, N=21（子脉冲的个数）, F = 20MHz （频率步进值）, 合成带宽B = 400MHz，（2）载频f0 = 5.321GHz, N=81（子脉冲的个数）, F = 5MHz（频率步进值） , 合成带宽B = 400MHz。目标参数：四个分别位于995，1000，1001和1005米处, 其反射系数为1, 1.5, 2.25, 3.375(Compression experiment of stepped frequency signal)

JS Tree树形菜单，确实是够经典的WEB版树形菜单特效，带有节点连接线的树状折叠菜单，点击的时候会展开子菜单，适合用于WEB版的信息管理系统、CMS后台系统中，你喜欢的话，你可以用在任意你想要的地方。

proteus仿真tm128×64oled 触摸屏，内仿真库，可以看看，虽然不是很完善，但可以说是个小创举，对于软件仿真的实际性有很有参考价值！(proteus simulation tm128 × 64oled touch screen, within the simulation library, you can see, although not perfect, but it can be said is a small undertaking, for the software simulation of the actual nature of a good reference!)
