NPG power system data

解常微分方程的Matlab程序 字符串ypfun是用以表示f(t, y)的M文件名, tspan=[t0, tfinal]表示自变量初值t0和终值tf y0表示初值向量y0，可选参数options为用odeset设置精度等参数。 输出列向量tout表示节点，输出矩阵yout 表示数值解，每一列对应y的一个分量。若无输出参数，则作出图形。(Solution of ordinary differential equations of the Matlab program is used to indicate ypfun string f (t, y) M-file name, tspan = [t0, tfinal] said that since the variable t0 initial and final values of tf y0, said initial vector y0 , optional parameters to set options for the use of odeset accuracy and other parameters. The output column vector tout that node, the output matrix yout that of numerical analysis, each column corresponds to y of a component. If there are no output parameters, then make a graph.)

本文从理论上对LFM-CW 雷达进行了信号分析，并对LFM-CW 雷达的信号 处理方法进行了简单研究，最后通过仿真程序验证了该信号处理方法（距离/多普勒处理） 在计算运动目标距离和速度时的正确性，为LFM-CW 雷达信号处理提供了理论依据。(This paper analyze the signal of LFM-CW radar by theory, and research the signal process method of LFM-CW radar. In the end, this paper validate the signal process method’s correctness to calculate the moving target’s distance and speed by emulate program. This paper offer the theory for the signal process method of LFM-CW radar.)
