以下几个matlab程序对雷达常用的线性调频信号（lfm信号）进行脉冲压缩时的关键问题进行了仿真，其中包括旁瓣抑制影响（加窗与不加窗）、多卜勒频移影响，并对时域脉压与频域脉压结果进行了对比分析，供相关技术人员参考。(Matlab following procedures commonly used on the radar LFM signal (lfm signal) for pulse compression at the time of the key issues of simulation, including the impact of sidelobe suppression (plus a window with no window), the impact of Doppler frequency shift, time domain and frequency domain pulse pressure and pulse pressure results of comparative analysis of relevant technical personnel for reference.)

对matlab编程过程中常见的指令进行了总结，并按照字母顺序进行排序，我觉得还不错(Matlab programming on a common course of instruction were summarized, and sorted in alphabetical order, I feel pretty good)

matlib.h头文件是vc和matlab混合编程的接口头文件，主要是简化vc中的数学公式计算(matlib.h the first document is a mixed vc and matlab programming interface header file, mainly to simplify the mathematical formula vc calculation)

计算了沿CMPL厚度方向，可以看出，CMPL的界面从第一个网格移动了1/4个网格，这是为了保证，CMPL更新的电场和磁场的数目相同。(The thickness direction along CMPL is calculated.It can be seen that the interface of CMPL moves 1/4 of the grid from the first grid to ensure that the number of electric and magnetic fields updated by CMPL is the same.)

Matlab实现的cdma编程，初学者最容易理解和学习，有利于初涉cdma仿真的学习者很有帮助(Matlab realize the cdma programming, beginners learn the most easy to understand and help learners初涉simulation cdma helpful)

定步长ODE4、ODE5算法，用法和ode45相似 唯一不同的就是ode45是[t,y]=ode45(), 这个是y=ode4()，因为是定步长的(Fixed-step ODE4, ODE5 algorithms, usage, and the only difference is similar to ode45 ode45 is [t, y] = ode45 (), this is y = ode4 (), because the step length is fixed)
