频率步进信号在雷达成像等需要大带宽的场景十分有用，该文件为国外经典文献，值得参考(Stepped frequency radar imaging signal in scenes that require large bandwidth is useful, the document for foreign classic literature, it is also useful)

常规波束形成，一个期望信号，一个干扰，高斯白噪声(the CBF simulation)

考虑雨衰 阴影 和多径影响，使用拉亚普诺夫指数的公式，抑制载波型差分相位调制。( Consider shadow rain attenuation and multipath effects Raya Punuo Fu index using the formula, Suppressed carrier type differential phase modulation.)

hough变换的检测函数，调试成功的，可以用，对于圆检测很有帮助，大家可以学习一下(hough transform function testing, debugging successful, you can use, very helpful for circle detection, we can learn about)

this program is for bwfw power flow.

说明：  复杂网络BA模型matlab代码，返回网络图的邻接矩阵，代码中采用稀疏矩阵，极大地释放内存，提高效率。(BA model complex network matlab code, return to the network adjacency matrix, the code used in sparse matrix, which greatly release memory and improve efficiency.)
