雷达对4个目标进行脉冲压缩和mti，mtd(Pulse compression and mti radar on the four goals, MTD)

说明：  通过时域转换为频域，在频域中截取低频部分，去掉高频部分将结果再转换到时域以实现低通滤波的功能。(Through the time domain is converted to frequency domain, in the frequency domain low-frequency part of the interception, to remove high-frequency part of the results and then switch to the time domain in order to achieve low-pass filter function.)

关于雷达系统仿真和分析，完整代码，值得学习(On the radar system simulation and analysis, the complete code, it is worth learning)

计算水准网的条件平差初级代码，可以酌情修改使用！！！(Conditions adjustment is calculated net primary level code can be modified to use discretion! ! !)

objective-c textfield 下拉菜单实现(objective-c textfield drop-down menu to achieve)

Fundamentals of Electromagnetic with Matlab very good book for EM via MATLAB for Electrical Engineering

fun with arrays and learning

matlab以及汇编语言实现的锅炉水位的控。(matlab as well as the assembly language to achieve the control of boiler water level.)

This program generate a GUI botton to stop any DAQ aquisition

基于坐标变换的电机模型，采用maltab/simulink建立的模型，三相交流电压型输入。(Motor model based on coordinate transformation maltab/simulink established model, three-phase AC voltage input.)
