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)

电力系统潮流计算体现在数学就上是多元非线性方程组的求解问题，求解的方法有很多种。牛顿—拉夫逊法是数学上解非线性方程式的有效方法，收敛性好、迭代次数少。将牛顿—拉夫逊法用于潮流计算是以导纳矩阵为基础的，由于利用了导纳矩阵的对称性、稀疏性及节点编号顺序优化等技巧，使牛顿—拉夫逊法解题规模和计算速度进一步提高，此算法至今仍是潮流计算中广泛采用的优秀算法。(Power flow calculation in power system is a problem of solving multivariate non-linear equations in mathematics. There are many methods to solve it. Newton-Raphson method is an effective method for solving nonlinear equations in mathematics. It has good convergence and fewer iterations. The application of Newton-Raphson method to power flow calculation is based on admittance matrix. Because of the use of symmetry, sparsity and optimization of node number sequence of admittance matrix, the scale and speed of Newton-Raphson method are further improved. So far, this algorithm is still an excellent one widely used in power flow calculation.)
