This script will attempt to find the band gaps in a phononic crystal by carrying out a Plane Wave Expansion of the various quantities using square array method. There are 2 programs, one for short and the other one is for acoustic long

众多恒虚警检测（CFAR）算法都是基于单元平均（CA:Cell Avarage）的方法，该算法需要较大的运算量。本程序给出了基于有序统计（OS:Order Statistic）的CFAR检测算法，弥补了CA_CFAR检测算法的不足，同时还配有本人硕士毕业论文中的检测图像以及实验结果，具有一定的参考价值。(CA_CFAR algorithm often requires large computational complexity. OS_CFAR algorithm is presented, which can make up the disadvantages in CA_CFAR. In the meantime, some processed images are given, which has a high value of reference.)
