中文说明：在空间DOA估计中，需要面型的阵元排布才可以，此程序设为8+8的麦克风L型分布，利用几何关系也可以恢复出DOA估计
English Description：
In the spatial DOA estimation, the array element arrangement of the surface type is needed. This program is set as the L-shape distribution of 8 + 8 microphone, and the DOA estimation can be recovered by using the geometric relationship
