摘　　要：文章基于麦克风阵列的声源定位技术,提出了交叉谱声源定位算法。该算法通过调整信号的加权系数,使得扫描方向的信号在接收端实现信号增强。基于MATLAB编写了定位算法的核心代码,通过时域延迟求和与向量求和的可视化,展示算法的物理意义。通过8*8阵元实验,验证了所提出方法的有效性,为实际应用中的声源定位提供了算法支持。A cross spectral sound source localization algorithm is proposed based on microphone array technology for sound source localization.This algorithm enhances the signal in the scanning direction at the receiving end by adjusting the weighting coefficients of the signal.The core code of the positioning algorithm was written based on MATLAB,and the physical significance of the algorithm was demonstrated through visualization of time-domain delay summation and vector summation.The effectiveness of the proposed method was verified through 8*8 array element experiments,providing algorithm support for sound source localization in practical applications.
