说明：  张小飞版阵列信号处理 matlab程序代码(Zhang Xiaofei's Array Signal Processing Matlab Program Code)

分析二维正方格子上的逾渗问题，通过编写程序，得到临界概率 P 及临界指数 (PS:程序功能简单介绍:yushen.m 中计算了 Pinf 和 p 的关系，yushenmain.m 调用 yushen.m 来 计算不同 p 下的 Pinf;yushenhuixuan.m 中计算了 Rs 和 p 的关系，yushenmain2.m 调用 yushenhuixuan.m 来计算不同 p 下的 Rs。具体的实现程序中均有注释。)(The percolation problem on two dimensional square lattice is analyzed, and the critical probability P and critical exponent are obtained by programming. (PS: program functions simply: the relationship between Pinf and P is calculated in yushen.m, yushenmain.m is called yushen.m to calculate Pinf under different p; the relationship between Rs and P is calculated in yushenhuixuan.m, and yushenmain2.m invokes to calculate the differences under different P. There are annotations in the specific implementation program. ))

说明：  可以用其计算信噪比，只需要输入原信号和带噪声信号即可。还有一段EMD分解程序(It can be used to calculate the signal-to-noise ratio, only need to input the original signal and the signal with noise.)

线性调频信号扩展目标回波，有关雷达发射波形并产生回波(Extended target echo of LFM signal)

说明：  dji mobile sdk搭建好的简单模型 方便直接下载使用(Simple model is easy to download and use directly.)
